How to build my own computer

A significant percentage of computer users eventually reach the point where, instead of buying a new machine, they ask: How do I build my own computer? This is especially true of gaming computers, and to a lesser extent, gaming laptops. Below is a short guide to help users to build their first computer.

What you need

Tools While it is usually possible to assemble a computer with no more tools that a small Phillips screwdriver and a bit of thermal paste, having a flat-bladed variation, and a pair of needle-nosed pliers available makes the job easier. Parts Deciding which parts to use is actually far more difficult and important than the assembly, simply because of the variety of options, and all parts should be decided on before making any purchases.
First, decide what the machine will be used for, then choose a motherboard, processor, and video card that will do the job. Be sure to verify that these parts, along with the RAM (Random Access Memory) and power supply unit will all work together.
Even though it may seem intimidating at first, it's easy to do once you understand the different options.
Next, you will need to consider the peripheral parts you will need, both inside and outside the computer.
Wireless cards, sound cards, hard drives, disk drives, and the case that you will be using should all be decided on with available space in mind. Many motherboards now come with on-board sound processing, and a USB wieless card can be plugged into the outside of the case, saving space inside, if necessary.
Cooling fans also come in different varieties, so be sure to choose fans that will fit in the spaces provided and are compatible with the availible outlets in your motherboard or power supply.
Finally, choose any monitors, printers, or other exterior hardware that you will be using.

Assembly

This isn't as difficult as most people assume. As long as you did the necessary research, it is simply a matter of plugging parts into the appropriate slots on the motherboard.
One very important note is to remember to use a small amount of thermal paste when connecting the processor's heat sink. Forgetting to do so can result in your CPU overheating. This can destroy not only your CPU, but also other parts of your computer.
Also note that the contact portions of the components should not be touched, as contamination can be detrimental to their function.
Finally, don't plug the machine in until fully assembled. Electronics are very sensitive to static and power fluctuation.

Operating System

Installing an operating system is as easy as plugging a CD into the disk drive and following the instructions.
