Is it necessary to always buy brand new computer hardware products? What is wrong in purchasing used computer hardware devices? Well, there is no harm in opting for used devices as long as you know the extent to which the device has been used and the extent of wear and tear.

If the hard disk under consideration belonged to your friend and if you know that it was maintained well, then you can definitely give it a try. If you know that the computer was dusted regularly and kept in good condition, you can buy the disk and install the same in your computer. Of course, risk of failure of hard disk due to excessive usage will definitely be present. However, this does not mean that brand new hard disk do not fail. Even that happens.

As long as they prepared to take regular backups and not get stranded, you are free to purchase computer hardware that has been used before. Of course, there is no point in buying a used keyboard or used mouse because these devices are cheap that you probably will have to get free used devices to even think of buying it. Further, the keyboard and mouse happen to be used very often.

In fact, it is impossible to carry out any command on the computer without the help of the keyboard or the mouse. Hence, there is no point in trying to save money on these accessories.

As far as used a computer chips are concerned, you should not have any problem installing the same provided you find compatible devices. Finding RAM, hard disk, motherboard and other accessories compatible with the chip under consideration will be the most difficult task. There is no harm in going in for used products as long as you get a good deal with good value for money and do not expect the used device to function like a brand new one.

What precautions and should you take if you are trying to repair computer hardware on your own? This is a high risk job. You can end up with a huge repair bill if you mess this task. However, it is not impossible either. Just keep the following precautions in mind when trying to repair the computer on your own.

Firstly, prevent static buildup on your body. A small jolt of static electricity is more than sufficient to destroy the component. Want your RAM to work well even after you repair the computer? Prevent static.

Secondly, begin by cleaning the inside of the computer before starting the repairs. Do this even if it is not essential to carry out the repairs. It is only when you clean the computer can you proceed to find out what the problem is. In many cases, the fact that the computer was not dusted properly is the root cause of the problem.

Avoid opening and tinkering with hardware still covered by the warranty period. If you intend to still go on, make sure you use the web to know what you ought to do. That is to say, you should know the solution and not just think you know the probable solution. If you open the computer when it is under warranty, you will have to pay money to get the job done by the professional. The only way to avoid this is to repair the computer on your own.

There is no point in sacrificing year warranty only to take a look inside the computer. That would mean you would have lost warranty for absolutely no benefit whatsoever.

Before proceeding further, make it a point to memorize how the wiring and the parts are placed on the circuit board. Use a digital camera to take a few snaps so that you can set the device back properly once it is fixed.

Hardware for your Cyberspace Odyssey

Exploded view of a personal computer

The physical components of a personal computer are known as computer hardware. Some of these are the monitor, the motherboard, the disc drives, the keyboard and the mouse. There is also a case, or chassis that contains the internal components. All of these, plus an operating system and many software applications are what make up your friend the computer.
Most people would recognize the monitor, or the screen which displays the information output; the keyboard, upon which you type your input; and the mouse, that cute little pointing device that sits by the keyboard with the long wire tail. But not everyone is as familiar with the internal components.
The main one of these is the motherboard. With a name straight out of  science fiction, the motherboard is a large rectangle with integrated circuitry that, like Hal, from 2001 Space Odyssey, is the hub of all activity in your personal computer. It is the Great Connector. Hmmmm…because this is the motherboard, let’s call her Henrietta.
One of the components that Henrietta connects is the CPU, or the Central Processing Unit, which you could say is the ‘brains’ of the operation. The CPU does the calculations that allow the computer to function.  Maybe this is the part that we should name Hal.  And maybe, just like Hal, when your computer seems to have a mind of its own, this is the part you should try to reason with. But good luck with that. They didn’t have much luck with Hal in the movie either.
Perhaps this would be a job for Chip, the Chip Set, that does all the talking between Hal (the CPU) and the other components of the system. There is RAM, the Random Access Memory that stores all the applications and the current Operating System. There are also disk drives, expansion cards, power suppliers and so much more. Like all the passengers on Hal’s space ship, each piece of computer hardware has a specific job to do to keep your computer running so you can continue on your own Cyberspace Odyssey here in 2010.
