How to Fix a Computer Crash

If your computer crashes unexpectedly, everything comes to a halt. Prior to crashing your computer will likely start freezing up. This is an indication that your computer has to be fixed before it gives up completely. Fixing the computer does not need to involve replacement of the computer with a new one. Your current computer likely just needs a little attention.

Identifying the reason for crashing is essential prior to fixing the computer. The initial step is to reboot your computer. If the rebooting goes smoothly, it is apparent that you are facing a problem with your registry. If you cannot reboot instantly, then rebooting your computer in safe mode and locating a registry cleaner to fix your problem is essential.

Every file present in your registry contains a command or direction for every program and application on your computer. Registry files are the files that give your computer the instructions for what to do next. If these registry files get corrupt or misplaced, your computer fails to understand what to do. In these instances, your computer loses control, eventually leading to a crash.

At this stage the priority is to fix these registry files. In such situations it is suggested that you do not try to fix the registry yourself. Immediately find registry cleaner software and scan your computer to locate any errors. This software will identify all the missing entries or errors, restoring them right away. In many cases, your computer will be back to normal. It is recommended that you run this software once a month for best results.

Another cause of crashes is when new software is installed. If you have recently installed a new program or file, this could also be the source of the problem. You should locate the program and uninstall it. In case you are incapable of booting up your computer in normal mode, you are advised to try booting in safe mode first. If the new program is at fault, removing it should solve the problem. Obviously you would not re-install that program later on.

Most computer crashes occur due to a problem with the computer's registry files. This is the core reason for any crash. So, running registry cleaning software and eliminating all errors is essential to avoid computer crashes in the future. Subsequently, fixing the registry files will keep you from having to ask the question 'how do I fix a computer crash' again.

Computer Eyeglasses - What Are They?

As computers become a more integral part of today's lifestyle and practices, new medical conditions are developing as a result of their usage. The most common to date is computer vision syndrome (CVS), with symptoms that include double vision, itching eyes, headaches, blurred vision, eye pain and irritation, tired and burning eyes, watering or dry eyes, eye fatigue, eye strain and soreness. One would never imagine that such a useful and innovative tool could cause so much physical discomfort! As a result of CVS, science professionals seized the opportunity to create computer eyeglasses to alleviate these common conditions and make computer usage less painful and more comfortable.

The symptoms of CVS affect adults as well as children. Although children normally have different requirements for near and distance vision glasses,computer eyeglasses can be used universally for both groups. Please note that near and distance vision glasses should not be used as replacements for computer glasses. They do not serve the same purpose, and in some cases will cause more harm than good. If you are experiencing other vision problems not related to computer usage, please see a specialist to get your eyes tested.

Computer eyeglasses can be purchased in most pharmacies and drug stores and are usually inexpensive. However, beware! Some manufacturers use inexpensive tinted lenses and market them as computer eyeglasses, so your best bet would be to get a pair of prescription glasses from your doctor. That way, you can get a pair of glasses tailored for computer usage, as well as for any other secondary need like reading or driving.

Getting computer eyeglasses with a light tint would also prove beneficial for your eyes. Although the main reason for symptoms of CVS is the fact that the eyes are constantly re-focusing, spending a lot of time in brightly lit offices also produces some of the same symptoms. By using lightly tinted computer glasses, your eyes will be better able to focus, while the lighting in the room is being adjusted to the correct level.

Not every computer user needs computer eyeglasses, but most people who use the computer frequently throughout the day will stand the chance of experiencing negative symptoms. We still recommend that you invest in a pair in case you fall into that category! Besides, computer eyeglasses can be beneficial in the long run by reducing excessive focusing demands on your eyes. They may also be useful in preventing or retarding development of any eye conditions that could result from computer usage.

Investing in a good pair of computer eyeglasses is using the proactive approach. Although the problems may not yet start to show their ugly heads, getting the eyeglasses will fix them before they actually start. After all, everybody wants to be able to witness the constant evolution of one of modern man's most impressive technological advancements to date.

Computer Graphics Introduction - How Can I Use Them?

Images are all around us. They can be found in magazines, books, on television, and in movies. Once upon a time, these images had to be created by hand. But advances in technology, especially in the last 20 years, have made computer graphics easy to make.

First of all, what is a computer graphic? Put simply, a computer graphic is any image that has been created or modified using a computer. Some techniques used in computer graphics have been around for a long time, and are simply a computerized way of doing things that have been done by hand. Other techniques are fairly complicated to do by hand, but a computer makes them much easier to do.

One of the most common uses for computer graphics today is retouching photographs. Using a computer, you can do any number of things, from removing blemishes to taking things out of a picture that you don't want in there. With computer graphics, you can cut out part of one image to stand alone or to put in another image. Don't like the color of a shirt? You can change it. Another fun trick is to make the photo a black and white, but with one part of the image in full color. With a good program, you are only limited by your imagination in changing a photo.

As fun as changing photos is, you can do so much more with computer graphics. You can use computer graphics to create headlines that stand out. You can create titles for books, magazines, or even web pages with ease on the computer. Computer graphics allows you to do a lot of things with text, including making them appear 3 dimensional.

Some people like to use computer graphics to "paint" a picture. Computer graphics can be used to make any kind of picture you want, including cartoons and various kinds of art. Using the computer can allow the digital painter to blend colors in ways that are difficult, if not impossible, to do in real life.

One of the most exciting areas of computer graphics in the last decade has to be that of 3D graphics. Now, I'm not talking about making images appear to be 3D like you can with some paint tools. In 3D graphics, you create a 3 dimensional model of the object you want to make, give it texture and color, and render it into an image. Rendering is taking a 3D model and turning it into a graphic image that can be used in various ways.

Why is 3d computer graphics so exciting right now? If you've been to a movie in the last couple of years, particularly a blockbuster, chances are that you've seen computer graphics in action. The images are getting more realistic. That's making it harder to tell what is computer generated and what isn't.

With computer graphics today, you can do just about anything. It takes a lot of time and training to get good, but it can be worth the effort. The great thing is that even learning just the basics you can start impressing your friends. Using computer graphics can make your web pages, posters, and presentations more exciting and visually stimulating.

Securing Your Computer

The moment your computer connects to the Internet, you're leaving your computer to be exploited by viruses, hackers, and all sorts of malware, even if the computer is unattended! For any computer connected to the Internet, security is a must to defend against online threats.

A good first step is protecting your surfing experience by upgrading or switching your web browser. Always check to see if your web browser has a new version available. A newer version of a browser usually protects fixes the security flaws of a previous version and can add new functionality to increase your web experience. Sometimes, switching to another web browser can offer a better return in security than upgrading it. Switching from Internet Explorer to Firefox is an example. Internet explorer is an extremely popular web browser: over 80% of computer users run this software to browse the Internet. Internet Explorer's popularity is what makes the browser an also popular target for malicious websites and programs to exploit. What makes Internet Explorer and Firefox so different if both just browse the net? Their differences lie all "under the hood" of how the software runs and how tight the code is from flaws and bugs. This is why a security hole can apply in one browser but not in another. Download Firefox free at firefox.com and secure you web surfing. Firefox will take minute or two to download depending on your connection and setting it up is a breeze!

A web browser is a makes up the first level of defense when you're online browsing but what about when you're not browsing? Windows has hundreds of communication ports that deal with internet traffic. You're web browser only deals with a few when its in use. Whats watching over the other ports? Hopefully, you have a firewall because an unprotected port is vulnerable to outside attacks. The reality of this happening to you is very high: a person, without much hacking know-how, can easily sweep a small country for unprotected computers in a few days using special programs and steal and corrupt you data. A firewall closes communication ports not in use; and, for all other open ports, the firewall uses logic to reject traffic from a questionable source. Windows XP comes with its own built-in firewall to protect you from inbound attacks but not from outbound from inside your computer if its already compromised by malware. Luckily you can prevent the latter by simply avoiding websites and downloads known for packing malware. You can complement or even replace your Windows firewall with another dedicated commercial firewall that can protect you from both inbound and outbound attacks.You can research a bit on what each firewall provides and their licenses they give to the end-user to see what appeals to you. With a computer protected by a secure web browser, a powerful firewall, and a careful user, the need for an anti-virus is optional. Just remember a firewall can prevent online attacks, but can't stop infections.

After a web browser and a firewall, an anti-virus program can make up your third layer of defense in fighting an online threat before it can infect your computer. Modern anti-virus programs come with real-time scanning engines to delete a virus once it enters your computer's memory. If you've been using a computer for a while and never ran an anti-virus scan, you may be infected and don't even know it. Some commercial anti-virus companies offer a free diagnoses of your computer through their website and remedies. Its important to know if you're computer is "clean" before trying any computer-safety practices mentioned in this article, or what ever you do won't go as planned. If your computer comes out clean, just have a firewall on and be careful on how you surf the web; you don't have to have a anti-virus and save on computer resources unless you want to! If you're computer is always exposed to questionable files or used by people who aren't as security-savvy as you, then an anti-virus is another must. Take for example if a person is ferrying their work with a flash drive from your computer to a computer at school and back again. School computers are notorious for being virus-ridden because of the many students that recklessly use the computer. If you have people sharing the computer, you should put up an anti-virus to protect the computer from the possibly unsafe surfing habits.Remember though that no anti-virus software can possible catch every virus created. Hundreds are made every month and anti-virus programs can only catch the most common ones. In last ditch efforts in dealing with a virus not detected by an anti-virus, you'll need to back up and scan your important files, reformat your hard drive, and reinstall your operating system. This fact about viruses doesn't put you in immediate danger yet; your computer's chances of catching a rare or a brand-new virus is proportionally small. Follow safe computer practices!

Finally, your last defense is your operating system. Generally, it is the weakest and pretty much the target of hackers and malware but it does give some protection that is well complemented with firewall and anti-virus protection. For example, Windows XP prevents important system files from being changed or deleted to an extent and can disable permissions of regular accounts to edit system settings. Such features can only be found in new versions of Windows. Older versions such as Windows 98 and Windows ME don't benefit from the same security features as Windows 2000, XP, and Vista. Upgrading to a new stable version of Windows is a good thing.

Computer Forensics Files - The Little Dame That Wouldn't - Real CSI Cases from Burgess Forensics #14

The stories are true; the names and places have been changed to protect the potentially guilty.

A dame, a rich guy, and an email account: what more do you need for a story?

I was in my office one fine spring day in Marin studying the benefits of Eastern philosophy, engaged in my special snoring meditation, when the buzzing of the telephone dragged me back to the present. It was Sam & Dave - not the Soul Men, but the lawyers in the Valley. They had a situation. A computer expert was heading over to their offices to make a copy of their client's computer - the dame's laptop - to try to prove that she sent endearing emails to a scorned male - the rich guy...Mr. Silicon Valley.

See, rich guy had not been so rich until some computer hardware of his design had been snapped up by a big player in the computer world for a hefty sum. Newly rich Mr. Silicon decided to try his hand at picture books - picture books of natural looking young ladies in their native birthday attire. The hook was that they would be all natural - no silicone for Mr. Silicon.

One day, Mr. S was driving through the Rockies when he espied a liberated young lady. Liberated in the sense that she was 17, but living on her own. S offered to liberate her from a deadend waitress job if she would come live in his Valley mansion. It would all be very Platonic - they'd each have their own end of the mansion - and she would work with the picture book office staff.

But as our young lady reached adulthood, Mr. S became enamored enough to make our lovely waif a bit uncomfortable. She thought he was acting like a creep. She wanted out - out of the office and out of the mansion. The word "harassment" strikes fear into the heart of many an employer, and Sam & Dave were looking for a settlement to enrich all involved. But Mr. S was not to give up so easily. He maintained that the lovely Miss had been sending him endearing loveletters from her America OnLine account. Sure enough, her account had sent those letters - but had she been the one to send them? AOL has a setting that allows a user to sign in automatically - that is, to sign in without having to type in a password. This setting is nearly always a mistake, unless no one else is ever near your computer. I always recommend to my clients that they take the extra 5 seconds out of their busy schedules to type an actual password. You might have guessed that her AOL was set to automatically login.

But the letters had been sent after she had already left the office. That meant that if she had sent them, she must have drafted them on her laptop from home. A deal was made. Mr. S hired a computer expert to do some digital discovery. He'd make an identical copy of the hard disk from her laptop, while sitting in Sam & Dave's conference room. This is where I entered the picture. S & D wanted me to make sure that the hired thugs … er, experts … would not pull any funny stuff. I went to observe on the day of the copying.

Just a short half hour or so after their scheduled arrival, the other experts arrived. They were decked out in full company regalia. Their bright jackets, hats, and business cards announced their offices in New York, Tokyo, London, Hong Kong, and Los Angeles. These guys were apparently internationally jetting big shots. As it turned out, only one was the bigshot - the other guy was the gofer. Bigshot sat in a chair and bragged about his exploits while Gofer unloaded their equipment. A large, high-powered desktop computer, with external drives hooked up through an Adaptec SCSI host adapter appeared on the tabletop. A briefcase full of secret computer forensic software was opened to reveal its treasures. The golden floppy disk was removed from the briefcase. Bigshot examined the laptop, and announced, "We can't do this copy - there's no floppy drive."

I was a little dumbfounded. Surely these guys had all of the computer forensic equipment known to mankind. "I have EnCase and ByteBack," he said, "but I need to boot from a floppy drive to make a copy." This was at least half accurate. Whenever a drive is operated in a Windows environment, Windows writes bits and pieces of data to the drive. Under such circumstances, the data is changed and is not a true identical, "bit-for-bit" copy. It's not a forensic image. But when the system is booted from a DOS diskette, nothing gets written to the hard disks. This is what the fellow was looking to do.

I suggested he remove the hard disk from the laptop, and hook it up through a write-blocker to his desktop computer. "What's a write-blocker?" he asked. "Gofer, do we have any write blockers?" Gofer's look of befuddlement answered for him. I explained to Bigshot International that a write blocker is a device that can be hooked up between the hard disk and the cable it is attached to, or between an external enclosure holding the hard disk and the USB cable leading to the computer. The MyKey NoWrite FPU is one of my favorites. The Tableau works well. The Disk Jockey Forensic wasn't around then. The DriveDock & others would have been fine. But he didn't have any by anyone.

Still, removing the hard disk, attaching it to his system and booting the system from his floppy diskette should have been fine. I suggested as much. "How do you take out the hard disk?" he asked. Apparently laptops are different in London and Hong Kong and those other places he had offices.

I asked S & D's secretary for a little Phillips screwdriver, and removed the hard disk for Our Man. "It doesn't hook up to my IDE cable," he said. You see, laptop IDE hard disks and desktop IDE hard disks are different sizes. Most in laptops are 2.5" and most in desktops are 3.5" and never the twain shall meet - at least, not on the same cable. The 40-pin connector on the laptop is, unsurprisingly, smaller in size. "How about an adapter?" I said. "Have you a 2.5" to 3.5" adapter?"

"Have we got one, Gofer?" Befuddlement answered wordlessly again. I suggested a quick run to the local computer store. I even volunteered to go, for the Mensa-level technical skill was getting to me a little at that point.

Twenty minutes later, we had an adapter from a local Mom & Pop computer shop. Some adapters for laptop drives hook up the opposite way from what is intuitive. Once I warned against hooking the laptop drive up backwards, Bigshot got everything set up right, the computer booted, and a good copy seemed like it was only minutes away. That is, until I heard, "My target disk drive isn't big enough." Well, I didn't want him to have to go all the way to Tokyo or New York for another. I suggested hooking up additional drives from his special briefcase to the SCSI bus, then changing the image size. Many computer forensic programs allow one to acquire a large drive as several or many contiguous images of a smaller size. By changing his configuration, Mr. B could make many successive CD-sized images of about 650 MB each, instead of one giant one that wouldn't fit in the available space in any one of his hard drives.

With the copy proceeding apace, I asked S&D what I should do next. We saw the estimated time of completion was about five hours away! I wondered if sitting waiting for electrons to move was the best use of my time and their money, and they seemed to think it was not. I explained what to look out for - any cables being unplugged, any keyboards being typed on, any utterances of "oops" or "oh no!" from the Dynamic Duo making the copies. The job should be mostly babysitting until the copy was completed. I headed back to the airport, and to my office at Burgess Forensics to finish my interrupted meditation.

How did it all turn out? There were no loving emails drafted on the laptop. The computer she had used at the office was being used to send bogus emails from her auto logon AOL account. Mr. S was ready to settle… after just one more meeting.

As part of the settlement, Mr. S & our lovely Miss had one last lunch together. They met at an outdoor café. It might have been romantic, but Miss sat well out of reach, her lawyer sat just out of earshot a couple of tables to the West. The attorney for S sat just out of earshot a couple of tables to the North. Everybody ate lunch. S paid the bill - three bills, actually - one for lunches, one for the lawyers, and one settlement for the lovely lady. She then walked away and never looked back.

While I never met the lady, I was alerted to look for her on a fashion show. There she was, on the TV, looking like the waif models are apparently supposed to resemble. I couldn't tell if she looked any richer, but I hoped she would spend some of the settlement on a few more lunches - she could have filled out a little and looked a bit more…natural. But that's outside my area of expertise. A nutritionist I'm not - I do computers.

This is just one of the many "CSI* - Computer Forensics Files: Real Cases from Burgess Forensics" cases in the file. Stay tuned for more stories of deceit uncovered by science.

Why Is My Computer Slow?

Why is my computer slow? I bet you have asked yourself that very question time and time again. And for the most part, you probably just can not figure it out. Ask the guy next to you, and they probably don’t have the foggiest idea either. I mean, you may get the “spyware” answer, but this most likely is not the case.

The first place I check when my computer starts to run slower is the registry. Yes, the registry. Most people don’t even know what, or where the registry is, and especially don’t understand how this can slow a computer down. Let me explain.

Basically, the registry files contain information and settings for all of the software, hardware, operating system software, and anything else running on your computer. Mess any of these files up, and the computer does not know how to function. The computer goes to start up the software, looks for the registry files, and either can not find it or finds something that does not look like it is suppose to look like. It then just sits there: it does not know what to do next. This is where the “hanging” or “locking up” of your computer comes from. These files will need to be fixed.

To fix the registry files, find a good quality registry repair software and run it on your computer. This is not something you can just do by yourself without any software. You can really mess some stuff up. So, use a registry repair software, and it will tell you how many files are corrupted and need to be fixed. Just tell the software to fix it and it restores all of the registry files to their correct configuration. It is really that simple. It may take only about 10 minutes to perform this check. And then as a maintenance item for your computer, I would recommend performing this registry fix at least once a week. This will always ensure your registry files are good, and keep your computer running with no freezing. So if you find yourself asking why is my computer slow, I would check the registry files first.

E-Commerce Supporting Technologies - Computer, Computer Networking, Internet, Internet Connectivity

E-Commerce as the word suggests means doing business on the internet or on-line. The scope of business may involve:
• selling hard goods on-line such as a phone, computer or shoes

• Electronic goods such as e-books, mp3 music, software, graphics or pictures

• selling ideas or services

To sell the goods the merchant has to have a website or a virtual store on the internet for him to sell the goods on line. A prospective customer finds that site, buys goods on it, pays owner using a credit card or via other mode. Merchant receives payment and deliver the goods and supports the customer. Practically, that’s e-commerce in its simplest sense.

In between those e-commerce transaction a lot technology are involve to complete the sale. For instance, the merchant has to design and build a website developed using a complex programming language called HTML. Merchant has to register a domain name to identity his business on the internet. All information and products from his on-line store or business are encoded and stored on the merchant’s computer server or hosted by a third-party web hosting company. In order for the customer to find the merchant’s site, he needs a computer that is in turn connected to a system popularly known as the internet, for him to be able to visit the merchant’s site.

The Personal Computer in relation to E-Commerce

A PC or Personal Computer is a computing device or tool built around a microprocessor. It has lots of different parts -- memory, a hard disk, a modem, etc...That work together. It is also called general purpose equipment. General purpose means that you can do many different things with a computer. You can use it to type documents, send e-mail, browse the Web and play games.

On each own, the computer can be used to expedite the processing and storing of information such as word processing. It can also be made to transmit and receive information from other computers. These computers can talk and exchange information from each other thru a common computer language or protocol. The PC is the most valuable and core-technology needed to drive E-Commerce and Internet Business.

Computer Network in relation to E-Commerce

Two or several computers can be physically linked and made to communicate with other computers with in a local network (LAN). The term use to describe this interconnection is called networking. Networking of computers can be made using either a wired (cable) or wireless (radio) type of connection. Usually, networking or the linking of computers is subject to the range or distance limitation because the signal and quality of communication will degrade as distance increases. Computer Networking is applied for most on-line internet business for an efficient and productive E-Commerce business.

The Internet in relation to E-Commerce

The internet is a system that connects computer networks. The system of internet enables the interconnection of computers all over the world. It allows your computer to get stored information from other computers far away.

The protocol (TCP/IP) or language when computer communicate in a network is similar to the one used on the internet. That is why computers around the world understand each other despite different maker and place of manufacture.

Lots of computers all over the world are stored with lots and lots of information. The internet system hooked them together. If you have access to the Internet, you can read, hear and view all this information from your own computer. The Internet is all the reason behind the existence of E-Commerce and without internet connectivity virtual on-line business will totally cease to exist.

Telecommunication in relation to E-Commerce

A different type of technology is needed to transmit information from one computer to another over long distances. Telecommunication companies come into the picture to service the requirement of connecting one computer network to another computer network using different kinds of transmission technology.
Telecommunication is a broad term as it also covers not only data communication such as the internet but includes voice telephony as well.

Telecommunication companies are driving internet businesses to achieve internet connectivity. Without them one could never put their business on-line as only telecom companies are able to link networks over very vast geographical distances.

Connectivity in relation to E-Commerce

Connectivity is a broader term than networking. Networking refers to the physical (wired) or virtual (wireless) connection between computers. Connectivity refers to the state of being connected. For instance, a computer can be sync to a phone, music player and other devices. Internet access or the state of being connected to the internet information super-highway is a classic example of connectivity.
Internet Connectivity is important both in urban and rural-remote regions of the world.

Some regions are suffering from lack of telecommunication infrastructure thus internet access service is very limited. In order to achieve internet connectivity, remote villages either use satellite link, wireless radio systems and long-range phone extenders. Some communities have established telecentres which serve as a communication hub and outside link to the rest of the world. All forms of connectivity including internet connectivity are helping push the envelope of internet business as a whole.

So you've read about e-commerce overview and its supporting technologies. Try to imagine and picture out how e-commerce is being practice and how important are those technologies to making it possible.

Choosing The Right Notebook Computer

Notebook computers have incresed in popularity over the last few years. This buldging market for notebook computers gives you more choice than ever before. The flipside is that the wide range makes it that much more difficult to choose the right notebook computer without a little knowledge.

The most important questions is always: What will I use my notebook computer for?

This driving question should lead all purchases. No amount of techno-babble should make you get something that you just don't need. Stay informed and you will get the best results from you notebook computer.

Notebook computers are, by nature, designed to be moved around easily. More than likely you will use it for work, this is the place where the most commuting takes place and the place you will most likely transport your computer to during the day.

Smaller notebook computers are never quite as fast as their slightly bigger counterparts. The small sizes don't allow for the latest and fastest parts that need a lot of breathing room as they can become very hot. Lot's of time away from a power source necessitates getting a good battery and having a computer than uses the battery efficiently. In the digital age, the internet is very important for many people, so wireless connectivity is essential. Applications on a notebook computer will probably consist of software like the Microsoft Office Suite or similar and a few other programs. Small monitors and limited processing power will rule out most serious gaming, but for a notebook computer it is hardly necessary considering what it is intended for. Fancy graphics cards are an option, but are hardly worth it as everything else plays against it, except if you get a huge, powerful laptop computer, which is very cumbersome. Let's look at these in a little more detail.

Consider carefully the size of notebook computer that you need. There are a lot of different sizes with notebook computers. Browsing around your local computer store will give you a much clearer picture of the sizes, even if you buy online, checking a real one out first is highly recommended. The size is pretty much dictated by the screen size, with sizes running past 15 inches in some cases. A notebook computer with a smaller screen makes it more portable. An option for a smaller notebook comptuer is a wider screen. WXGA and other wide screen formats give a little extra width, allowing a much more roomy desktop. They are usually in a 16:9 width to height ratio, while 4:3 is the desktop standard. This extra width is perfect as it allows you to keep two programs open side-by-side without closing them all the time.

The processor is the next major consideration when choosing your notebook computer. In a general sense they are usually toned down version of their desktop counterparts. They are clocked lower, meaning they run slower than intended, but the upside is much reduced power consumption which is good for battery life. Any processor should have enough clout for office type software. AMD and Intel are the major names for notebook computer processors, although Intel has the lion's share of the mobile computing market.

After these two major items, the other bits are really just extras. There is room to choose and pick with most of these other parts on your notebook computer.

Essential extras include USB ports, wireless networking capabilities, network port and modem port. USB is the standard for peripherals that connect to the notebook computer. Another one that is sometimes used for video and others is FireWire, it's useful to have, but not essential. Wireless networking is becoming standard, but make sure. There should be a convenient way to turn off the wireless card as they suck a lot of battery power when in use and can be turned off when not in use. A network port is so standard that there must be one, modem ports are so common they should not be missing.

Your DVD might be external or built-in, if it's external you could be choosy about which kind and brand you get, perhaps even a DVD writer. A DVD is not essential. If you notebook computer is a second computer and you have a main one at home, then you could forgo the DVD writer or the DVD drive altogether if you really need a compact notebook computer.

The mouse pad on the notebook should be easy to use and responsive. It should be out of the way enough not to interfere when typing. Keyboard layout needs to be good, even if it is smaller than standard.

Finally you might feel a little safer choosing a notebook computer from companies like Sony, Gateway, Dell, eMachines, Gateway, HP, Toshiba, Thinkpad, Acer or Fujitsu. They are all major notebook computer makers and will be able to back up their products with guarantees that they will deliver on.

Avoid disaster and anguish by making sure you visit our computer buying guide before buying ANYTHING for your computer.

With So Many Online Computer Repair Services Out There How Do You Chose The One To Fit Your Needs?

Popular belief among IT professionals is that people should tune-up their computers every 90 days like they would change the oil in their cars. Although most computer companies would like everyone to believe that they need a new computer 90% of computer users only need to have their system tuned up and their computer will be running like new, if not better. For example, when your car starts acting up do you just get rid of it, or do you take it to the local mechanic? After the mechanic tunes it up it runs smoothly again. Well you can think of the technicians who do computer repair as the mechanics. Once a tech diagnoses and repairs the problem your computer can run smoothly again.

Concentration on managing systems by preventing problems instead of reacting to problems after they have done possible damage is a new way of thinking. Since computers are not just for business anymore it is even more important that problems are prevented as often as possible. More and more people use their computers everyday for everything ranging from preschool learning activities to seniors ordering their prescriptions online. Not to mention how much time so many of us save by paying our bills and doing our shopping online. Wouldn't it be nice if a computer repair service would provide you with 150 gb free backup space to safeguard your invaluable documents and engineers would install and configure backup software for you to ensure your computers always have a backup. If your hard drive crashes or you delete a file, there would be no need to worry they could help you restore any files you need. Almost every PC user has encountered the nightmare of computer problems.

Often they start gradually: The computer starts running slower, or develops a minor problem that can easily be ignored. Before you know it, that minor problem has escalated to an in-your-face sort of thing. And then the real fun starts: You get to decide whether you would prefer to haul your computer in to a service center, where it may disappear for weeks on end, or deal with a service person's intrusion into your home. The only thing more frustrating than computer problems is talking to someone who only speaks in jargon or "computer-ese." Computer support specialists that explain technical issues clearly in plain English and are as patient, friendly and helpful as they are skilled at fixing your computer are very hard to find. We also understand that computer problems don't keep regular hours, so shouldn't computer repair services be available at all hours and have REAL LIVE PEOPLE available 24/7 to help you with all your computer needs. There is no longer any need to wait around for hours for a tech to make a costly house call when so many companies out there can connect remotely to your computer and basically offer you an instant solution as long as you can still connect to the internet through a high speed connection. Family owned and operated companies who are focused on treating customers the way they want to be treated and know how valuable your time is are few and farther between.

The revolutionary new way is to make services available all hours of the day or night from the convenience of your own home through Remote Support. It's hard enough to find quality time to spend with our families without adding the hassle of unplugging all those cords that we had so carefully childproofed just to haul the computer to someone so they can tell you to drop a chunk of your savings into a new one. Computer Life Support is one of these new computer repair companies and was started by two brothers in the IT field. They grew tired of the horror stories of people who have received computer support from some geek. Only to be ripped off in the end and still having computer problems. Wouldn't it be nice to put an end to these horror stories. There are other companies out there that provide a similar service such as 3geeksandamouse, gurus2go, hiwired just to name a few. So go out and compare services and see what's out there to keep your computer running at it's highest capacity.

Increase Computer Security With Biometrics

Computer security is high on the list of priorities for most people today. Because computers have recently become very mobile, there is a very distinct danger that the personal data that a person keeps in their mobile computer can very well end up in the hands of the wrong kind of people.

There has been a lot of technology focused on providing the necessary security features in computers so that the data that is stored in them is kept safe. However, there is always one thing that typically undermines whatever security feature has been implemented on the computer. A personal computer or laptop is principally a private piece of property. As such, while the data that is stored in it is also very personal, the person using the computer is often prone to disregarding whatever security protocol is used to protect the data and computer. This is simply because he or she is assuming that the computer will remain personal and safe from other hands.

Unfortunately, time and again, that belief has been proven false, which is why computer security needs to be developed around the idea of security being second nature to the user. To organically merge security with the individual, a lot of people and organizations aim to increase computer security with biometrics.

Essentially, biometrics consists of a fingerprint scan that serves as a security barrier for the computer. Once installed in a computer, no potential computer user can access the computer unless he or she is specifically identified as a legitimate user of that computer.

As a device, the biometric reader scans the information from the fingerprints of a person. This acts as a key to opening up the computer. Unless the person has the right fingerprints to match those stored in the biometric device, the computer remains inaccessible. Thus, the computer is well protected from illegitimate users.

There are several advantages when people increase computer security with biometrics. For one thing, it is a very natural and quick way to register the person with the intended computer he or she is supposed to use. Accessing a laptop, for example, only takes putting a finger against the biometric scanner and having it check whether the scanned fingerprint matches with the fingerprint on file for the biometrics device. Once a match is confirmed, the computer becomes fully usable. Thus, security with biometrics is quick and easy.

What's more, the fingerprints of a person are unique to each individual. Fingerprints do not match between different people. Thus, there is no chance that two individuals can open a computer that is keyed only for one person’s fingerprint.

Thus, for companies and individuals who are looking to ensure their data, one of the best things that they can do is to increase computer security with biometrics. Not only is biometrics one of the safest ways to secure a computer, it is also one of the most natural and convenient. Every personal computer that stores confidential and personal data — and what personal computer does not — should use biometrics to increase security.

Computer Hackers Wanted For Organized Cyber Crime

Low Risk - High Return - Work Your Own Hours
The Ultimate Get Rich Quick Scheme

Wow! Can you imagine a help wanted ad like that in your local newspaper or pay-per-click ad in your favorite search engine?

Yet, organized cyber crime has become the most profitable - low risk - high return crime of our age. Hundreds of thousands of hackers are quietly using the Internet, hiding behind thousands of captured computers, stealing identities and money from innocent people like you and me. Sadly, there is little chance the hacker will ever get caught.

Organized cyber crime has become a big-time profession. Professional hackers make it their daily job to take advantage of current computer security trends and send out threats like Spam, phishing e-mails, Trojan horses containing key loggers, hijackers and more, all targeted to steal your identity and ultimately your money.

These cyber criminals can work alone or in groups. Either way, their first goal is to capture computers and turn them into zombies or bots. These are computers that the hacker controls without the owners knowledge.

As more and more computers are captured, the hacker develops an Army of computers or botnet that can be used for any number of criminal activities. The botnet may send out Spam e-mails, and Trojan horses. A botnet can cause denial-of-service attacks on web sites extorting money from the web site owners. This whole time the hacker is hiding behind a string of computers under his control. Tracing back to the hacker is nearly impossible.

Hacker Tools For Sale

Anyone can take advantage of the computer security trends and become a part of the organized cyber crime world. The tools of the trade are everywhere. You can find web sites that promote the use of these tools. What do you want? Here's a partial list of items you can find on the Internet:

· Remote Access Tools - known as RATs. These tools allow remote access to a computer. They were originally developed for white hat hackers to remotely repair computers. Now, this is a major tool in a cyber criminal's toolbox.

· Key logger Tools - Corporations and even parents find these tools necessary to keep everyone in line on the Internet. Unfortunately, hackers have learned how to use these tools to steal your private information.

· Video And Audio Systems - Hackers have tools that will penetrate your computer systems and watch your every move through the camera mounted on your computer or microphone that came with your computer.

· Voip And Broadband Phone Services - you can easily find tools such as web dialer worms to break into computers and listen to conversations or even dial and use the phone service. How hard is it for a criminal to place drug purchases or conduct terrorist activities with your computer?

· Computer Memory Storage - hackers can acquire tools to section off your computer and store anything they want like child pornography, criminal records and more.

· Spamming Tools - want to send e-mail out of someone else's computer? Just purchase this easy to use software and you can make that happen. Hackers send millions of Spam e-mails every day making up over 90 percent of all e-mail sent out worldwide.

· Create Your Own Virus - Yes, it's true. There are many web sites offering to mutate a current virus to your needs. Lately, virus attacks have been more targeted. That's why you haven't heard about massive virus attacks lately.

· Drive By Spyware - There are some web sites that promote that they will pay you to allow them to place a tool on your web site that puts spyware on every computer that visits the site. The more computers infected the more money you make.

· Computer Scrambling Devices - you can purchase tools that will scramble all or some of the information on a computer. Simply invade a computer, scramble important information, leave a message telling the victim to pay a few hundred dollars ransom to an overseas account and they will send the code to unscramble the information.

This list could go on and on. Organized cyber crime uses every tool they can find or devise to take advantage of the current computer trends and enhance their threats.

The headline reads: Computer Hackers Wanted For Organized Cyber Crime! The sub headline should say, "The general public is indifferent and isn't doing much to protect themselves. The Timing couldn't be better."

Organized cyber crime has moved, for the most part, from targeting large businesses to individuals and small business. Criminals know that this targeted group has little knowledge of computer security and a small amount of money to invest in their protection. They view this group as easy prey. So far, they are right on target.

The sad truth is that most people either don't seem to care or don't know what to do. Most of those that don't know what to do don't do anything about it, either. That's the current computer security trend. As a result, organized cyber crime and computer security threats continue to grow at an accelerating pace. Over $67 billion was stolen last year. Over eight million identities have been stolen every year for years and years back.

What Can We Do To Fight Organized Cyber Crime And Turn These Computer Security Trends Around?

For the most part, criminals are lazy. They are looking for the low road - not the high road. Making yourself a hard target to attack is your first defense against organized cyber crime and computer security threats.

The old saying, "knowledge is power," is most important. Make sure everyone in your home or business understands the threats and is careful not to allow these on a computer. However, even with the best knowledge there can be accidental leaks from opening Spam e-mail, drive-by-hacking from a web site, downloading infected cds and more.

Here are some tips to protect your home and business:

· Make sure you keep up with the latest most up-to-date Microsoft Windows patches
· Use an industrial grade bi-directional firewall. Most over-the-counter and products offered by Internet services don't offer this quality technology
· Make sure you have up-to-date antivirus protection
· Make sure you have best-of-breed anitspyware protection. Antispyware and antiviruses are different computer security threats and require different protection technologies.
· Avoid web sites that may have spyware including gambling and pornography.

The best protection is using the same computer security solutions used by major corporations around the world. A solution that uses overlapping technologies to prevent antiviruses, spyware and other computer security threats.

Keeping your computer's software and operating system clean is essential to have an optimal running computer. If you have a computer that is bogged down by incompatible software, viruses and spyware, your computer will suffer from performance issues and can crash repeatedly.

A Small Business Approach To Computer Downtime

The muscle of a modern small business
If it’s true that the backbone of any small business is its employees, then I believe it’s fair to say that the muscle of many small businesses would have to be their computers. Plain and simple, business today is performed electronically. Whether it’s a day-trader trading stocks over the internet, a lawyer, physician or other professional looking up data, or a shopkeeper tracking prices and sales, computers are often an essential “tool of their trades”.

In fact, in the majority of professions where a computer is used, it is often not possible to effectively perform the job role without it. Sure the day-trader could continuously call their broker every five minutes for stock quotes, but in practical terms their business is reduced to a standstill. An analogy would be a carpenter trying to work without his hammer.

However, when you consider complexity, comparing a PC to a hammer is kind of like comparing a space shuttle to a bicycle. The average computer is a marvel of complexity. In fact, when we break it down, we’re not even talking about a single device. Computer systems are made up of a collection of hardware and software components, usually made by different manufacturers, working together for a common purpose. And it follows simple logic; the more complex the system, the more that can go wrong. All it often takes for a business to come grinding to a halt is for one of those components to malfunction.

Computer downtime can result from numerous circumstances. Viruses and spyware are waiting to infect your PC through the internet, email and even commonly used applications. Internet hacking, identity theft and other cyber crimes are all on the rise. Compatibility issues and missing or corrupt drivers plague both hardware and software alike. And problems with the installation and use of everyday programs can cause no end of headaches.

While the above points can raise a number of questions in the average small businesspersons mind around the costs associated with these downtimes and what can be done to minimize them, straight answers are often not easily found. In this article, we will attempt to analyze these questions and determine the best approach for professionals and small businesses to take in dealing with computer downtime.

Options for dealing with downtime
Questions surrounding downtime related costs have become such a hot topic on the Internet that an online calculator has been developed by NTA Monitor Ltd. to assist individuals and companies in determining the cost of computer downtime (You can try it out at http://www.nta-monitor.com/services/downtimecalc.htm). While this calculator can be quite handy, it is often not readily apparent what numbers to use for “total downtime” or “labor costs”. So lets just do some calculations of our own to determine the total overall costs that a professional or small business faces due to downtime and see if we can determine the best approach to resolving downtime related incidents.

The first and hardest question to answer is “how long is an average downtime incident for a small business?” Well, I’m afraid that there is no easy answer to this. While the average time is completely dependant on the nature of the problem, for this example we can piece together a typical scenario of events to create our timeframe.

When a typical computer issue or problem arises, there are a number of avenues that a small business owner can take to see it resolved. As most small businesses can obviously not afford to pay for a full or even part-time IT staff, the “do it yourself” method is often first employed. Resources such as friends, family and the internet are consulted for answers and some trial and error approaches, such as using generic “fix all” programs, are tried. That failing, a local computer service shops can be called for on-site or drop-off support. Or as a new and increasingly popular alternative, a remote service provider can be used.

Depending on the user’s knowledge of computers, the “do it yourself” approach can sometimes work and considering the time spent doing research, trial and error fixes, etc. the average issue can be resolved in as little a an hour or two. But sadly, more often than not, the time spent does not result in a solution and it is added to the overall incident time. So to make our calculations simpler, let’s deduce that on average the amount of self help time spent saves as much time as it looses and instead we will focus on three remaining options; on-site, drop-off and remote support. We will base our calculations on an eight hour work day.

While being a more expensive option, on-site services can often result in a quicker resolution time than drop-off service. Usually a technician can be scheduled for “same day” or “next day” service. On average this results in a total downtime of around eight hours.

A small business can save some money on the hourly rate it is charged by choosing to drop off their PC for service instead of having a technician come to them. While some service depots have longer waiting lists that result in the business owner losing their PC for numerous days or even weeks, shopping around for service usually results in an average turn around time of two to three days. Factoring in the time spent disconnecting and reconnecting your system, as well as the time spent dropping it off and picking it up, it’s reasonable to say that the average downtime for drop-off service is in the neighborhood of 24 business hours.

Finally, there is a lesser known option for small businesses that has grown out of advances in “desktop sharing” technologies. Professional remote computer service and support technicians can access computers directly through their internet connections to resolve computer issues.

Michael Hovila, the owner of AdvanceServe Remote PC Services (http://www.remotepcservices.com) informs us that “remote computer repair and support services are available to any computer that is connected to the Internet, anywhere in North America; It can be from home or business, a hotel suite or while telecommuting, or even through local wireless 'hotspots'. We can even connect though your home or corporate firewall... Then just sit back and watch as our remote technician controls your mouse and keyboard to diagnose and fix your computer problems or to demonstrate how to use or configure common applications.”

The hourly rate for remote support usually falls somewhere between that of local drop off and onsite service rates, while the downtime is reduced to an average of two hours per incident as a result of not having to wait for service. However, not all issues can be resolved remotely. Physical problems such as hardware failures still need to be dealt with by a “hands on” technician.

Calculating the costs
So which option is best for the small business owner? Let’s do some quick and simple math to find out. Based on average “resolution time” claims from numerous sources, I have decided to use two hours as the mean resolution time for these calculations.

For onsite service, rates are charged either on a “per hour” or “per incident” basis. Since we are calculating “per hour”, I compared the rates of four leading national on-site service providers and worked out an average of $100 US/hour for onsite support. So the total cost for a two hour service call ends up being $200.

Next we examine the cost of the drop-off service option. Prices in this category vary a little more depending on the service provider but a comparison of two national providers and two “mom and pop” local service depots resulted in an average hourly rate of $60 US per hour. Based on our two hour resolution time the labor cost for this option is $120.

Finally there is the remote support option. An average comparison of four trusted national providers resulted in a rate of $80 per hour. For a two hour resolution time the total cost is $160.

But we’re not done yet. Now we have to factor in the loss of wages that has resulted from the down time. 2003 Bureau of Labor statistics suggest that individuals who use computers for a living make an average of $36.20 an hour in wages and benefits. So using that figure as the “per hour” loss due to downtime for a single computer, we can calculate and compare the total cost of downtime for each of our three timelines.

Option One – Onsite Service

Total Downtime: 8 hours

Lost wages: $36.20x8=$289.60

Cost of Service: $200

Total Cost of Downtime: $489.60 per PC

Option Two – Drop Off Service

Total Downtime: 20 hours

Lost Wages: $36.20x20=$724

Cost of Service: $120

Total Cost of Downtime: $844 per PC

Option Three – Remote Service

Total Downtime: 2 hours

Lost Wages: $36.20x2=$72.40

Cost of Service: $160

Total Cost of Downtime: $232.40 per PC

Well, based on total costs the hands down choice appears to be “Remote Computer Support”. However, there are a couple additional factors that should be examined a little closer before making a final decision. As mentioned earlier, remote support has its limitations. The primary two being, the issue cannot be fixed remotely if it is a result of a physical problem with a component, and the computer being serviced must have working internet access.

To determine how the first limitation factors in, we need to determine what percentage of computer problems are hardware vs. software related. Vendor data shows that software issues are actually 40 times more common than hardware issues. Therefore, in theory, when the computer can still boot up and access the internet, around 97% of problems can be solved remotely.

The best approach

I now believe we have enough data to make a well rounded decision regarding the best approach for professionals and small businesses when dealing with computer downtime.

Step Zero: The reason I’ve added a “step zero” is that an age old saying still applies to modern problems; an ounce of prevention is worth a pound of cure. Take the time to have routine computer maintenance performed on your PC. There are a number of great “self help” guides to keeping your PC running smoothly. Or consider signing up for a routine maintenance plan by a professional remote provider if you are either not comfortable with, or do not have the time to maintain your own computers. But no amount of maintenance can prevent the inevitable, so when downtime does occure…

Step one: If you are reasonably knowledgeable in computers and you can still access the internet, it can’t hurt to take a few minutes to search online or with your peers for answers. If the answer is not apparent within fifteen minutes of searching, there is a good chance the solution is not simple enough for the average computer user to solve and professional assistance should be considered.

Step two: To save time and money, your next best step is to try a remote service provider. They can often resolve your issue quickly and get you back to making money instead of spending it. Even though they cannot resolve physical problems, you will still come out much farther ahead on average by trying a remote technician first.

Step three: In the few cases where the issue ends up being hardware related, your next best choice would be the onsite provider. Many remote providers have local affiliates who they can recommend you to and can provide you with diagnostic information to pass on to the local technician, which may reduce the required support time.

Addendum: Since this article was first published, I have received a number of emails asking for my recommendations on the best choice for computer support providers in each of the areas I covered. So as requested, here are my choices for the top national providers. Please note that the following choices are simply based on my own research and experience:

From downtime to uptime

Computers are an essential part of most modern small businesses but when problems occur, the costs associated with them can quickly spiral out of control. However, a quick and well thought out response to computer downtime can save a small business hundreds or even thousands of dollars. I hope this guide will help you to be better prepared when your downtime comes because it’s not a matter of if; it’s a matter of when.

Computer Basics

A computer is not just one thing but is consisted of many parts that work together. A desktop computer is a computer intended for use at a single location only. It is usually bulky and consisted of many parts connected together by wires. Here are some of the basic parts of a desktop computer.

The CPU or Central Processing Unit. This is considered as the brain of the computer. This is what processed all the information and carries out the commands in your computer. This is regarded as the most important computer part because without this, your computer will cease to function.

The RAM or Random Access Memory. This is considered to be the short-term memory of the computer. The bigger memory capacity of your computer's RAM, the more files you will be able to store and more often, the faster your computer would work.

The motherboard. This is the main board in the computer. It contains many chips and circuitry. This is where the CPU and RAM are located.

The hard drive. This is where all the computer programs and information are stored.

The floppy/CD/DVD drive. Floppy drives are used less and less. This is where floppy disks are put in. CD/DVD drives are prominent today because of the high us of CD's and DVD's. Aside from reading CD's and DVD's, computers now have the ability to store information on them through a process called "burning."

The monitor. This is the computer screen that displays whatever you are doing on the computer. Today, computer monitors come in different shapes and sizes.

The keyboard. This looks like a typewriter and is what you use to type on the computer. This also serves as a control of whatever you are doing on your computer.

The mouse. This is used to control the pointer on the computer screen. It has two buttons, left and right, that is used to click and choose things on the computer screen.

A sound card found inside a computer allows for the output of audio through a computer's speakers or headphone. A video card on the other hand allows for the output of video that is displayed in the computer. Using both of these is usually helpful when using your computer for games or for viewing videos.

The power supply. This is connected to all computer parts and is what supplies power to all parts of the computer.

Aside from the basic computer parts, there are still many other parts that can be found on a desktop computer. You can add a printer to put into hard copy the files on your computer. A speaker, to hear the computer's audio. A scanner, to put in images into the computer. A webcam, to serve as a computer camera. A modem, used to connect your computer to the internet.

You may already know the parts mentioned or may have been familiar with them only now but whichever it may be, you are now ready to get yourself a new computer.

Guide to Choosing a Computer System for Your Child

Before going further into choosing computers for children, I believe that you would like to know the answer to the following question:

Why do children need computers?

The easiest answer for this one is: “A child needs a computer so that he can play computer games”. Everybody agrees. Nevertheless, let’s not just limit on the short term use of the computer… Let’s analyze a little the world we live in and see what can acomputer do for children.

Computers are starting to have more and more importance in our daily life. Almost everywhere you go, you find computers. At office or at home, a computer is almost indispensable.

Not knowing to use a computer, you find many difficulties. Moreover, things will not get easier in the future, because the world is getting more and more computerized. That is why your child should get accustomed and work with computers from an early age. If your child does this, it will be much easier for him to adapt to the ever-changing technology.

Educational products are nowadays released mostly on computer CD's.

More and more educational products for children are now released in the form of programs and electronic encyclopedias and can only be viewed with a computer, somehow forcing you to buy a computer for your child. Unlike the traditional learning methods, learning with a computer has the advantage of interactivity. Children love to learn with computers, because they can control the way they learn and what they learn.

Of course, a child will use a computer mainly to play computer games. At first, the computer will be for your child like a more expensive toy. The computer will be his favorite toy. Your child will play computer games the entire day. However, after a while, the child will settle down and start exploring the other sides of the computer.

At first, the only thing I was doing at my computer was playing. Then, as time passed, I started being interested in how computers work, the internet, 3D modeling and so on. Now I can say that I know a lot about computers.

The disadvantage of computers as toys is that it is a lot more expensive than other toys for children, but on the long term, the money you spend will come back multiplied many times in the form of knowledge for your child. That is why I do believe that a computer is a very good investment on the long run for you and your child.

Which computers for children to buy?

Since the main use of the computer for your child will be to play games, you should choose a fast system on which modern games will run smooth. Also, because modern computer games use lot’s of space, a high capacity hard drive is recommended. The computer you choose for your child should be equipped with a DVD, because DVD’s are starting to replace CD’s as main data transport medium.

Now that you have chosen a computer system for your child, all you need is a monitor. You can choose from two types of computer monitors: CRT and LCD. LCD monitors are the ones you usually find in a office. They are flat and do not produce radiations. However, they are not recommended for the purpose your child will use it, because of the slow reaction time. CRT computer monitors are bigger and cheaper. They are more indicated for children who like to play computer games a lot.

Top 5 Common Computer Problems and Solutions

If you own a computer, then you have probably encountered these computer problems before. Once you buy a computer, you must accept that sooner or later it will eventually crash due to a virus or some other massive error. If someone told you that your computer will last more than a decade, don't believe it because it is just a myth or another sales pitch. But of course, you should take care of it if you want it to last for its third year without any defects.

However, there are many people that would prefer to buy a new computer than spend some time trying to fix or figure out the problem with their laptop or desktop. Usually after the first two years, you will need some kind of maintenance because your computer will tend to lose its original speed and performance. Well, here are some if the common problems that a computer user usually experience.

You may ask why your computer has problems. To tell you frankly, most of the time the biggest problem that your computer has is YOU - the owner or the user. There are many people that neglect the first signs of computer problems. You shouldn't neglect those simple maintenance tasks that can enhance or prolong the life of your computer.

1. Computer speed or performance has slowed.

One of the things that computer owners usually notice is this. There are several reasons why this happens to your computer. Lack of maintenance, fragmented data, corrupted registry, spyware, and unnecessary loading of computer programs and services can surely affect your PC speed and performance. Managing your programs and cleaning your registry can easily boost your computer's performance speed up to 30%.

2. Computer system freezes and blue screens of death.

You need to do some serious diagnostic procedures to effectively know the problem with your computer. Computer virus or spyware are maybe some of the reasons why this is happening to your computer. Update your anti-spyware immediately to avoid this kind of problem and thoroughly scan your computer to see if it has any viruses or spywares. If you find that your computer is free from spyware then updating your hardware drive is the next step. Hardware drives makes it easier for your computer to effectively communicate with other hardware components. Without an updated driver the CPU locks up and may cause problems when you are using your computer. If that doesn't work try to increase your Computer RAM to help avoid computer freezes. By increasing the RAM you get more use out your computer's computing power.

3. The computer keeps on rebooting again and again.

This kind of problem is usually associated with hardware issue. Faulty power supply is usually the cause of this problem. Dirty or defective cooling fan is another reason why your computer is rebooting spontaneously. When your computer is trying to cool itself when the fan is defective it automatically switches off. Dust that accumulated in your computer can trap the heat inside which makes it hotter. What you should do is to clean the fan and make sure that it is running properly. Do not forget to check your power supply.

4. Noises and vibrations.

This one is almost certainly that your have hardware issue. High pitched noises can be caused by electronic components. Whatever the reason, you conduct a small investigation. Unplug your computer and remove the case and run the computer to discover the origin of noise. If a loose wire or faulty fan is not the one that is making the noise then it may be time to call a computer tech to help you with your problem.

5. Your browser home page changed itself.

It is known as "high-jacking" which is also caused by a Spyware installed on your system. The spyware in your computer installed a java script into your web browser that tells your browser to change settings hence changing the default home page of your browser. What you can do is to run an anti-virus or spyware program to remove the spyware from your computer.

All of the problems stated in this article can be avoided easily by simply maintaining your computer. Do not panic when you are experiencing a computer problem with your PC because the key to fixing that problem is to properly diagnose to identify what's happening to your computer. Take a few minutes to run some diagnostic test or seek help in computer forums before you rush out to computer technical center.

Buying a Used Computer Online - What to Look For Step by Step Before You Make Your Purchase

There's one reason and one reason only to buy a used computer online, lack of money which is a good reason. For the purpose of this article, the term computer shall include laptops. This article will tell you what to look for and what not to look for in a used computer, step by step.

I would only consider buying a used computer if you can't afford to buy the computer you want new and can't afford a new computer at a level below that computer provided its features still have what you want. IE, if you can't afford to spend $750 for a new Core 2 Duo computer but can afford to spend $500 on a new Core Duo computer or $500 on a used Core 2 Duo, I would probably get the new Core Duo Computer unless the features on the used Core 2 Duo you found you couldn't do without. The main advantage of buying a computer used is the warranty and the ability to extend it, free technical help from the computer company and the fact that you know there is no spyware, adware and viruses on it and in all likelihood no pre-existing problems on the computer waiting to be discovered.

Once you decide you can only afford to get the computer you want used then the first thing I would do is look to to see if it's available online from a large company that sells refurbished computers with at least a 45-90 day warranty. Refurbished computers include computers whose boxes were opened and never used as well as returned computers with no problems and returned computers with problems. These companies usually buy refurbished computers in mass and test, repair and restore them as applicable to their original factory setting before they are resold, so you're not likely to get a stiff. If you are, you will be covered by their warranty. You usually can extend your warranty for a few years beyond the original 45-90 days, as long as it's before your original warranty expires.

The next step below that is buying your computer used online. Usually when you are buying a computer used online, there is no warranty. If you are not sure if a computer includes a certain feature on it, you need to contact the seller and have him confirm by email if it does or doesn't have that feature before you purchase it. Sellers are notorious for being deliberately vague on used computers. For instance, a few years ago I purchased a computer which the seller confirmed to me by email that it included an operating system and when I got it, of course it didn't but because I had this in writing he replaced it with one that had an operating system. If I didn't get him to confirm this, chances are he would have stated that nowhere in his sales description did he say an operating system was included and therefore he won't replace it. If you don't have a basic general knowledge of computers and you have a friend that does, I would have the friend check out the description before you make your purchase. Whatever you do, if you see the words "Sold as Is"- do not buy as that is the sellers way of saying you are stuck with it, once you receive it.

I would not purchase any computer that is not at least described as being in very good condition as most sellers have a tendency to describe the condition one level better then what it is. I also would not buy any computer that mentions any kind of problem in its sales listing even its been fixed as you're asking for trouble. You should make sure the memory, hard drive, operating system, size and CPU is listed and what you're looking for. Assuming everything is in order, I would insist that the seller cleans the computer of all spyware, adware and viruses, if applicable before they send it out. I once got a used laptop that I had to spend 5 hours cleaning that junk off it. Once you get the computer, run any security programs on it and if you see that the seller hasn't sent you a clean computer, either tell them to refund you for the the whole computer or tell him you'll keep it but you want a rebate for sending you an unclean computer.

One last thing before you make your purchase is to see what software is already on the computer and if there's something you don't want, ask the seller to uninstall it and if there's something you want kept on, tell the seller to leave it on. I would have the seller send you the computer UPS ground as its likelier to be damaged if sent by air, insured for the full purchase amount and requiring you to sign for it when delivered.

Once you get your computer I would as I said earlier, run any security programs you have to make sure there's no junk on it. I then would test the computer for its basic functions and once you have an internet connection established, download Belarc Advisor online which is a free download that reads what's exactly on your computer in detail to make sure everything you were told was on the computer is on the computer in terms of software, system, RAM, hardware, etc. I also would make sure you have an anti-virus program operational before you start surfing the web.

Web and Computer Security

Well, if that would have been said to me by my father when I was 2 years of age, I would have understood. But when today, my own computer tells me that when I am 34, I wonder why I spent $1500 on my computer hardware and software just to enjoy the (un-realized) benefits of this great and revolutionary information technology?

Today’s cyberspace is hazardous. None of today’s PC users can claim that they never had a computer virus issue or a PC security breach. Now, if you count today’s number of PC users worldwide, they will soon be 1 billion by 2010 according to analysts. When I see all the computer viruses, infections, trojans, and what not around me, and compare it with the 1 billion innocent computer users around the world, I simply feel sorry not only for those billion users but for myself too. But again, as a common user myself, I must admit it was not all doomsday for the whole industry since 1987 when I started to use computers. So, as a responsible member of this great IT revolution, I must share some of the best tips and tricks that I learned to use to make the minimum room for productivity on my computer.

Please note this is a tutorial for someone who has basic know-how of computer usage. For those who are newbies, I would recommend asking a local expert’s help before trying anything out mentioned in this tutorial. In that case, make room for payment from deep pocket. For your own convenience, print this tutorial for step-by-step instructions.

Whenever my computer is infected, I act on any of the following options;

1. FORMAT HARD DISK: I back up all of my data on a CD-Writer if it is still accessible. And then format the whole hard disk drive and re-install each and every application.

2. USE SOFTWARE: I exhaust all anti-virus and other software options. This is usually my first priority as compared to formatting the whole computer hard disk drives.

Now, let me explain both options in detail;

PRE-REQUISITES: Make sure you have a CD-Drive (Writer), empty writable CDs, Windows OS CD (bootable) that contains files such as Format.exe, Scandisk.exe, FDisk.exe, and Attrib.exe files. Microsoft Office CD, Anti-Virus CD, GoldenHawk CD Writing Software in DOS (copy2cd.exe and cdtools.exe), Serial Numbers of your License, Driver CDs of Motherboard, VGA, Network, Sound and Modem devices. Optionally, download (using www.download.com or www.tucows.com) these software from any Internet Café when your own computer is inaccessible and save it on a CD so that you can use it anytime for security purposes;

Golden Hawk DOS based CD Writing Software

HTech Fireman Windows based CD Writing Software

Driver Genius Pro

Partition Magic

AVG AntiVirus

SpywareBlaster & SpywareGuard

Spybot Search & Destroy

Ad-Aware

IE-SpyAd

ZoneAlarm

HiJackThis & CWShredder

I have intentionally avoided mention of many commercially good and more friendly software’s mention here as I wanted everything to do FREE without any additional costs apart from the usual OS licenses. For your own convenience, you can research Google or Yahoo search engines find further information about such commercial software and their availability / pricing.

1. FORMAT HARD DISK

I know it is painful and surgical type of solution, but sometimes, it is the ONLY solution left after exhausting all of our efforts to revive our computer machine after a virus attack. Follow this procedure;

Booting Up: Try booting your computer normally first and see if you can login easily. If you can’t or your computer hangs up, try holding F8 key when starting Windows and you will get the Safe Mode. Even if you don’t get the Safe Mode, don’t worry.

Power up your computer and press DEL key or F2 key to login your CMOS. In CMOS, go to Boot Preferences and make CD Drive as boot drive as your first boot drive and change the hard disk drive as the second boot drive. If you don’t see your CD Drive in the boot-up options, your CD Drive is not properly installed. Check the connectors or ask your CD Drive provider for instructions to install the CD Drive. Now, when your CD Drive is ready, insert your Windows OS CD in the CD Drive and restart your computer machine. When prompted, select the option “Boot from CD with CD Option”. When you get the prompt, Notice the CD Drive letter that was allocated to your CD Drive when it installed the CD Driver. It is usually D: drive or the last drive letter depending on the number of your partitions. Note it down as it is the actual drive letter where you will have to type a DOS command like d:

You should now be able to run all software utilities such as Format, Scandisk, FDisk or Windows Installation Setup.exe files. Right now, simply make sure they exist by typing a DOS command dir at the CD drive letter. If you don’t find it with this simple directory command, use dir/s filename to search the file. For example, to search fdisk.exe file, type dir/s fdisk.exe.

BACKING UP YOUR DATA: Before formatting your hard disk drive, please make sure you have proper back up of your critical data files such as Microsoft Word, Excel, Powerpoint, etc files on a CD or any other media for backup that you have access to. In this tutorial, we assume you have a CD-Writer installed for taking backups on Writeable CDs. Their capacity is usually 700MB or less. Here, you should seriously consider using Zipping software like WinZip or WinRAR.

VIA WINDOWS: If you can luckily login to your Windows OS, you should run the CD-Writer software such as HTech Fireman to back up all of your data on an empty CD. If you don’t know how to do it, read their user manual for detailed instruction set. If you can’t access your Windows OS, read on.

VIA DOS: Some of the files that you wish to make back-up, may be hidden. To un-hide them, use attrib *.* +r +s +h.

Now, use the software from Golden Hawk file named as copy2cd.exe to backup your data files or directories on a writeable CD. Before using this command, make sure you are in an appropriate path on the computer such as E:/ where the actual file copy2cd.exe file resides;

Copy2cd c:data*.* f:

Here we assumed that f: is a CD Writer drive. Now, repeat the same for all of your files to back up. When finished, run cdtools.exe command i.e. cdtools f: to finish by selecting option “Disc Finalization”.

If you can’t back up your data using the above-mentioned procedure, either ask an outside expert’s help personally or via internet. If all fails, forget your data forever and carry on installing a new OS as mentioned in this tutorial.

Backing up Your Drivers: An interesting tool to mentioned here is a software that automatically backs up all of your drivers of CD, modem, sound card, vga, usb, printer or just about anything that is currently installed on your system. But this software works only in an operational windows OS, and not in DOS. It is a good and time-saving practice to keep a backup of all of your drivers on a CD by using such a software. Its name is Driver Genius Pro and it is commercial software, not a freeware.

USING FDISK: You may skip this option and go straight to Formatting Hard Disk option, if you wish to use other useful partitions that may contain your data. Before going ahead with this option, Make sure there is no useful data left on your computer to be backed up. This option will delete all of the computer partitions and create new ones.

i) Boot up your computer using Windows OS CD.

ii) Run this command
fdisk

iii) Press option 3 to delete all current partitions.

iv) To create a new partition, select option 1 and select Y to answer the maximum size question by the program.

v) Next, select option 2

vi) Press Esc key to quit and restart your computer to

See the URL http://www.compguystechweb.com/troubleshooting/fdisk/fdisk_scr.html for detailed instructions alongwith screenshots. Now, that you have created the primary partition, you can continue to format the newly created partition. There is a very user-friendly but commercial software called Partition Magic by PowerQuest to manage your partitions easily after installation of Windows.

FORMATTING HARD DISK: Now that you have created new partitions, It is time to format them so that you can start installing Windows. This is how you make your C: drive usable by your Windows OS for installation. Boot up your computer with Windows CD and type format c: command at the prompt. When prompted for maximum size, press, YES. After complete processing you will be presented with the successful report about the formatting of the C: drive. Select your new drive name and press ENTER to finish.

INSTALLING WINDOWS: Microsoft has made it very easy for a newbie to install a completely new OS on a newly formatted partition. It is all wizard based and you simply have to click NEXT each time whenever asked a question. Boot up your computer from the Windows CD and select Start with CD Option. When on DOS prompt, change to the CD Drive that it just created which is usually d: if you have only one partition C. Now type command setup.exe to start the windows installation process.

During installation, make sure you properly name your PC as per your preferences and select your regions and Time zone. When finished, the computer will re-boot and during next re-boot it may ask some drivers of your Sound Card, VGA, Network, or other devices attached. Provide the requisite driver CDs and locate the paths of the appropriate drivers. If you are not sure, leave it like that and press NEXT to ignore. When your windows installation is complete, you can install Microsoft Office, setup internet connection and start using it as normally as you would. Please make sure you install all the security software such as anti-virus, anti-spyware, adware, and other software as mentioned in the next section.

2. USE SOFTWARE

Installing Anti-Virus: Download free AVG Antivirus software and install it. Make sure you get its free key from their website by registering. This software is not auto-updated for critical viruses and for an auto-update version, you will have to pay. If you wish to pay, we would recommend world’s most popular brands Symantec, McAfee and Trend Micros instead. No matter what Anti-Virus software you install, make sure you enable its Auto-Protect feature for automatic protection of your computer’s resources and in-coming or out-going emails from any virus attack. Some software even allow you to setup silent detection and destruction without any disturbance to your work. Further, they are auto-updated via internet at the regular interval that you setup. Hence, you can rest assured that whenever a security threat is spread all over the world, your software will automatically download the requisite updated version and install its defense on your computer.

BROWSER SECURITY: To setup your browser (Internet Explorer on Windows) for maximum security against the usual threats, follow this procedure;

i) Start up your browser

ii) Go to IE > Tools > Windows Update > Product Updates, and selected Security Updates to be automatically updated. Microsoft releases patches and security patches from time to time to make sure your system's security is up-to-date.

iii) Now, go to Internet Options/Security/Internet, press 'default level', then OK. Now press "Custom Level." In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to 'prompt', and 'Initialize and Script ActiveX controls not marked as safe" to 'disable'. Now you will be asked whether you want ActiveX objects to be executed and whether you want software to be installed. Sites that you know for sure are above suspicion can be moved to the Trusted Zone in Internet Option/security.

If you use another browser such as Firefox or Netscape, see their documentation on how to securely set it up against any such internet threats.

Installing Anti-Spyware: Spyware, adware, browser hijackers, and dialers are some of the fastest-growing threats on the Internet today. By simply browsing to a web page, your computer may become a victim. You can install SpywareBlaster and SpywareGuard to effectively guard your computer from such internet threats.

It includes Fast Real-Time Scanning engine for known spyware and heuristic/generic detection capabilities to catch new / mutated spyware and Download Protection along with Browser Hijacking Protection in real-time.

Simply download the software (free) from their website and install it on your system. Make sure you download its latest update too or enable its Auto-Update feature to be updated automatically in the background. Now, when you are ready, run the software to check the spyware on your computer. When spyware are found, it reports accordingly. Press "select all", then press option "kill all checked". Although it won't protect you from 100% spyware, But it is a very important extra layer of protection.

Next, install another software that is called Spybot Search & Destroy. It works exactly like SpywareBlaster, but it never hurts to have a double layer of spyware detection alongwith Spybot R&D.

Installing Anti-Adware: Adware is a common term used to describe potentially dangerous websites and scripts that do data-mining, aggressive advertising, Parasites, Scumware, selected traditional Trojans, Dialers, Malware, Browser hijackers, and tracking components. There is a very good software called Ad-Aware available to scan and remove such nuisances from your system.

To start using it, simply visit Lavasoft USA website and download its free non-commercial version of Ad-Aware Personal Edition. Run its setup program and install it. When prompted, ask it to scan your computer. If there are any adware found, it is detected and removed automatically by Ad-Aware. Run this software on a weekly or daily basis, if possible to keep your system clean.

In addition to the Ad-Aware, Internet Explorer comes with a very handy tool that allows you to block specific sites that may carry well-known advertisers, marketers, crapware pushers to the Restricted sites Zone. If you had to input 50000+ of such sites manually yourself, it would takes years. Luckily, there is a software that does it all automatically and it is called IE-SPYAD. Once you merge this list of sites and domains into the Registry, the web sites for these companies will not be able to use cookies, ActiveX controls, Java applets, or scripting to compromise your privacy or your PC while you surf the Net. Nor will they be able to use your browser to push unwanted pop-ups, cookies, or auto-installing programs on your PC. It is not an ad blocker. It will stop top unwanted crapware from being installed behind your back via "drive-by-downloads"; prevent the hijacking of your home page.

This Restricted sites list is based in part on info from: discussions in the SpywareInfo Forums and other forums that specialize in crapware removal major crapware reference sites: doxdesk, cexx.org, Kephyr.com, PestPatrol and SpywareGuide.

To start using it, simply download it from their website and run its install.bat file. Make sure you run its update as well soon after its installation.

INSTALLING FIREWALL: A firewall software acts as a defense shield against hackers, intruders, and blocks access attempts to your computer. ZoneAlarm is a professional firewall software that works in a stealth mode automatically and makes your computer invisible to anyone on the Internet.

Download it from ZoneLabs website and run its setup for installation. I recommend you use its Express Settings which automatically configures your most commonly used software like browser, chat messengers, ftp software to access internet, while blocks every other internet traffic in real-time. If any software or service tries to upload or download any data, it pops up an alert whereby you can allow or disallow such internet traffic.

Computer Slow Down: It is very common to see many complaining about their computer slow-down. The fastest and easiest cure is using Windows’ built-in Defragmenter utitlity that you can find in Startà Programs à Accessories à System Utitlities à Disk Defragmantor and run thorough defragmantation. It will take a while before it ends.

If your system’s performance does not improve after running defragmantation utility, consider scanning your computer via a software utility called HiJackThis which you can download and install on your system. Use this tool carefully as it is intended for advanced users only. HijackThis is a tool, that lists all installed browser add-on, buttons, startup items and allows you to inspect, and optionally remove selected items. The program can create a backup of your original settings and also ignore selected items. Additional features include a simple list of all startup items, default start page, online updates and more.

CWShredder is a utility for removing CoolWebSearch (aka CoolWwwSearch, YouFindAll, White-Pages.ws and a dozen other names). This tool will find and destroy all traces of the CoolWebSearch (CWS) hijacker on your system including redirections, IE slowdowns, start page changes, un-authorized addition of sites in IE Trusted Zone, and blocking access to IE options or setup.

Download CWShredder from their official website only as there is a similar named virus/trojan on the loose at various websites which you may accidently download and install, hence become more infected than being cured instead. When it is installed successfully, run the software to scan your local machine. Select the fix button & it will get rid of everything related to CoolWebSearch. Close ALL other programs & windows, including IE, before running CWShredder. Reboot after doing this.

I know there is still a lot left, but as I wanted to keep this tutorial as brief as possible, hence I covered only the critical elements here. I am sure you will have fewer breakdowns (if not ZERO0 and more productive hours on your computer. I would recommend you to setup all the software’s auto update and auto-check options to free your time for more productive things than just playing hide and seek with spywares, adwares or viruses. Happy and safe computing!
