Tips on how to Build a Desktop PC


The perfect computer is very different for a lot of people. Some may be interested in running heavy multimedia software for graphic designing, image editing and video rendering while others may want a computer to simply browse the web and work on documents and spreadsheets, there are also those who like to stick to hardcore gaming and others who want a bit of everything, so need a well rounded PC that can handle basic office work, play a little and crunch some basic software. Before buying a PC, you must first know what you want in it. There is just no point in picking out a ready made PC and settling for whatever it can or cannot do.

The basics

Every computer has three major parts- The display monitor, the input devices like the keyboard, mouse, touch pads and gaming controllers and the CPU. For a build, you will be concentrating on the CPU as the monitor and input devices can be anything you want as long as it is compatible.

The parts

The CPU or Central Processing Unit is the brain and the most important part of the computer as all the data crunching happens here. The CPU’s main components are:

  • Mother board
  • Memory (RAM)
  • Hard drive
  • Power supply
  • CD/DVD drive
  • Video and graphics cards (GPU)
  • Chassis and case


All of these items can be bought separately and from different brands. Just speak to any of your friends or the guy at the counter or just look it up online before you buy your stuff. Just make sure that all your parts match your motherboard and the motherboard sits as it should in the case. These are all the parts that go into most PCs anything else is only an optional add on.

The build

After you get the parts, it pretty much comes down to plugging in the right sockets in the right slots. First up, the CPU chip has to be mounted in. See the instructions given for direction and position. If it does not sit perfectly in place, you are doing it wrong. The heat sink and cooling fans normally come with the processor, so place those on the processing chip and screw in the diagonal, opposite sides. Again, they should all sit in perfectly. There is no pushing and prying needed. The RAM goes in next push straight down and clip both the ends, it goes in only one direction.

The PCI and GPU are next, slide them smoothly into place, finally the power supply, hard disk and the DVD drives have to be plugged in and wired. Look for the slots that are marked on the motherboard for each of them, including the tape wires and SATA connections. They are all marked and shaped individually and cannot be mixed up. Finally attach the back plate, the keyboard, mouse and monitor. Turn it on and install your OS of choice.
