Step-by-Step Guide to Build A PC

Building a computer is not at all a hectic task as people think it is. You can do it on your own without any prior knowledge about computers whatsoever. In this article we will try to show you how you can build a Office PC for basic use. All you need are the following components and a bit of patience.

Components Needed

  • CPU (Processor).
  • Motherboard.
  • RAM.
  • Hard Disk (HDD).
  • PSU (Power Supply Unit).
  • Cabinet.


This is the main heart of the computer. All the processing will be done through the CPU. Make sure to pick a CPU that will cater your needs accordingly. They range from single cores to all the way to octa cores. A dual core Intel i3 will probably be best fit for everything. Also another thing to note is the socket of the CPU as this will come very handy in the motherboard section.

The motherboard is where all the components of the computer sits on to make it functional. The CPU, RAM and GPU will be installed on the motherboard which will then be made to fit inside the chassis or cabinet.


Make sure to choose a motherboard that has the same socket as the CPU.


The RAM is the memory of the computer. The RAM will be installed on the motherboard along with CPU and GPU. There are tons of variations of RAM that are available to choose from. A minimum of 4GB of RAM will be required to be able to run Windows.


Make sure that the RAM is in range of the compatibility of the CPU memory support.

Hard Disk Drive

Hard Disk Drive is the storage container of all the files in the computer. A 1TB HDD will more than suffice for a computer.


PSUs are the power suppliers in the computer. They are responsible for powering up all the components in a computer. You can choose a 500 watts supplier with a good rating and that will be it. It is installed in the cabinet.


These make the chassis of the computer that we are going to build and all the components are going to be installed inside the cabinet.

Lets Get Building

1. Get all the parts you need

Getting all the parts before hand, unboxed and ready to be installed is a real time saver. Make sure to recheck the checklist to make sure that you don’t forget anything.

2. Start with the mobo

Start first with the motherboard. Keep all the screws and the wires ready from the box of the motherboard.

3. Install the CPU

First of all check the socket of the CPU that you are going to install then align it with the CPU socket in the motherboard. Place the CPU gently over the socket of the motherboard and let it rest on it keeping in mind that the pins are all placed in the holes of the socket. Apply the thermal paste on top of the CPU and place the heatsink atop the CPU followed by installing the fan over the heatsink. Plug the fan in the motherboard and you’re done.

4. Time for the RAM

Installing the RAM is very simple compared to the CPU so it is a no-brainer. All you have to do is find the DIMM slot on the motherboard and plug it in. It will make a click sound when it sets in place.

5. Setting all in the Cabinet

Set the motherboard installed with CPU and RAM down the cabinet and align it with the screw holes in the cabinet. Screw all the holes in the motherboard with the cabinet nice and tight. Install the Hard Disk Drive and the PSU in their respective places and screw them in as well.

6. Wiring Up

Now comes the tricky part wiring the computer accurately is a bit tricky and frustrating. You might fail to connect every wire accurately at the first go but don’t lose heart as even experienced PC enthusiasts also mess this up pretty often. Wire the PSU, Hard Disk and the Cabinet with the motherboard and give it a go!

7. Starting Up and loading Windows

Turn on the power and give it a go let it start up. If it does not start then make sure that the wires of the cabinet are connected properly and try again. If it does start then congrats you just made your first PC. All that is left is to just load up windows which deserves an in-depth article on its own (it will be soon uploaded).

Have a great day!
