BEFORE WE BEGIN….
The very first step in any instruction is to know and understand the parts you’re working with. When constructing a PC, the components you must handle are:
- A Motherboard
- The CPU
- RAM sticks
- A Graphics Card
- The Power Supply
- Computer Case
To get you started, these parts are available for purchase in a variety of stores and on their sites. Some common retailers of PC components are:

What is the Motherboard?
A motherboard is an essential part of a PC. It holds many things including the CPU, RAM, and a graphics card. A motherboard is absolutely necessary when it comes to building your own pc. Always make sure when buying parts, everything is compatible with the motherboard! A great website to use is https://pcpartpicker.com/list/, which eliminates incompatible items.
What is a CPU?
This is the computers “brain” so to speak. CPU stands for central processing unit. The CPU plugs into the motherboard, which is why it is important for both of these things to be compatible.
What is RAM?
Many of us have heard the word before, but wondered, what on earth are people talking about?! Well RAM is an acronym for random-access memory. They allow computers to run faster without lagging. We would recommend at least 4GB of RAM. Now where does the RAM go? Just like the CPU, it fits into the motherboard. Make sure you check the motherboard to see how many RAM slots are on it.
What is a Graphics Card?
This is a microprocessor specialized for taking information and turning it into images. It allows the computer to run at full speed by letting the CPU do its job. If you are planning to use your computer for gaming purposes, this is a necessity. Again, just like the CPU and RAM, a graphics card is installed onto the motherboard. 
What is a Power Supply?
A power supply is a very important part of a pc, and without it, your pc won’t work. When you plug your computer in, the power is high voltage (AC). However, a computer need low voltage power (DC). That’s where the power supply comes in. It converts AC power to DC power so that your computer can work. 
What is a Computer Case?
When you look at a typical pc, you see a rectangular frame with all this “stuff” inside. The computer case is the rectangular frame. It contains most of the parts of the computer. 
Now for the Actual Process…..
Step 1- Unscrew both side covers so you can have easy access to the insides of the computer.
Step 2- Disconnect all of the wires and remove them.
Step 3– Remove the Graphics Card from the Motherboard.
Step 4- Remove all cables attached to the motherboard and slowly unscrew it to take it out.
Step 5– (If you took your computer apart)… Unscrew the cooler and remove any existing thermal paste with a bit of rubbing alcohol.
CONGRATULATIONS! You have now taken apart your entire pc, and can now put it back together. The following presents how to do it.
Step 6- Time to apply the thermal paste! Insert the CPU onto the motherboard and then put a dot of thermal paste onto the center of the CPU. Put the cool on top and press straight down. Screw in the cooler. Make sure no thermal paste is leaking out of the sides.
**Thermal paste is a heat transferring agent. It is used to fill in a tiny gap that occurs when your CPU presses against your cooler.
Step 7: Now it is time to screw everything back into the case! Install the power supply, screw in the motherboard, install the graphics card, insert RAM, mount storage, and then wire everything.
Step 8: Once you have inserted everything and double checked it, you can close up the case and plug in the extras. Now you’re done, and it’s time to start up your computer!
