What You'll Need

Before you start building your computer, you'll need to gather some basic tools and components. Here's what you'll need:


  • Screwdriver set (Phillips and flathead)
  • Pliers
  • Anti-static wrist strap


  • Motherboard
  • CPU (Central Processing Unit)
  • RAM (Random Access Memory)
  • Storage (SSD or HDD)
  • Power Supply Unit (PSU)
  • Case
  • Cooling (fans or liquid cooling system)

Step-by-Step Guide

Now that you have all the necessary tools and components, you're ready to start building your computer. Here's a step-by-step guide:

Step 1: Prepare the Case

Start by removing the case panels and finding a suitable space to work. Make sure to ground yourself by wearing an anti-static wrist strap or touching a grounded object to prevent damage from static electricity. Install the standoffs in the case and screw in the motherboard.

Step 2: Install the CPU

Open the CPU socket on the motherboard and gently place the CPU inside. Make sure the notches on the CPU line up with the notches on the socket. Secure the CPU with the latch or retention mechanism.

Step 3: Install the Cooling System

If you're using a liquid cooling system, follow the manufacturer's instructions to install it. If you're using air cooling, install the fans on the case and attach them to the motherboard.

Step 4: Install RAM

Insert the RAM sticks into the corresponding slots on the motherboard. Make sure the notches on the RAM line up with the notches on the slots and press down until it clicks into place.

Step 5: Install Storage

Attach the storage device (SSD or HDD) to the case and connect it to the motherboard and power supply using the appropriate cables.

Step 6: Install the PSU

Attach the PSU to the case and connect the cables to the motherboard, CPU, GPU, and storage device.

Step 7: Connect Peripherals

Attach the monitor, keyboard, mouse, and any other peripherals to the appropriate ports on the motherboard.

Step 8: Power Up

Connect the power cable to the PSU and turn on the computer. If everything is connected properly, you should see the BIOS screen and be able to install your operating system.
