Install the motherboard and CPU

Clearly, a motherboard is the brain of your computer. So, before you install other parts of the PC, firstly you will have to deal with the motherboard. First of all, pick the right motherboard that you need to install. Even you have to find the right shape and size that must fit in the case. Find some handy tools like Philips screwdriver, empty case, Motherboard along with compatible CPU.

First and foremost, open the case and look at the interior carefully. Now, lay the motherboard and ensure that all the corresponding holes are aligned perfectly. Now secure the motherboard with the screws that comes to the case.

To install the CPU, unlock the socket first. With a little push, you can do it. Now just place the CPU inside the socket. For this, you have to find the corresponding corner in the socket. If it is correctly aligned, then it should simply fall.

Install the RAM

In every motherboard, there is an empty slot you will find where you can place a RAM. This step is much easier to be done. There are two slots you will find. Firstly, find the empty slot. For a new motherboard, there is no RAM you will find. But placing RAM in any empty slot is not the solution.

RAM must be installed according to the particular order. Because some motherboard has this manual to install a RAM. Otherwise, you can install a RAM in any empty slot. There is are some clips that need to open up. Now take the RAM and place it following the edge.

At this time, press the RAM gently and until it is seated. Next, you have to snap back the clip by pressing down.

Install the video card

Now you need a PCI card that needs to be installed. If there are any active connection with your Motherboard, then turn it off. It should be noted that it is dangerous to install a PCI Card in an active power connection. In every motherboard, there is a PCI card slot. But there is no fixed number for the slot. It depends on the model of the motherboard.

But keep it in mind, leaving someplace between the slots will help to keep things cool enough. There is some screw you will find in the slot cover. Take the PCI card out from the wrapping. In every PCI card, there is some metal bracket. This is the best place to hold the card. On the mounting bracket just push the card gently into the open slot. Without a doubt, secure it perfectly with the screw.
