Step 1: Mount Motherboard

Mount motherboard on standoffs so it isn't touching the case. Make sure that your standoffs are in the right place so you can mount the motherboard on them.

Step 2: Insert Processor

Install the processor onto the motherboard by unlocking the socket, lining up the triangle on the processor to the triangle on the motherboard, gently placing the processor in the socket without bending any pins, and locking it in place.

Step 3: Install CPU Fan

Apply a pea sized amount of thermal pase on to your CPU. Rotate pins on CPU fan counter clockwise. Place fan pins in the holes around the CPU. Press firmly on pins in opposite corners until you hear a click.

Step 4: Install RAM

Install the RAM sticks into their respective slots on the motherboard. Make sure the notches on the RAM stick are aligned with the notches on the slot and press firmly until you hear a click.

Step 5: Mount Power Supply

Mount the power supply in the case and connect the necessary cables to the motherboard, storage, and other components.

Step 6: Install Other Components

Install any additional components such as a graphics card, wireless card, or sound card into the appropriate slots on the motherboard.

Step 7: Connect Cables

Connect all necessary cables to the motherboard, including the power switch, reset switch, and LED cables.

Step 8: Test System

Turn on the power supply and test your system. If everything is working properly, you should see the BIOS screen appear. If it doesn't the PC will make a beep. 1 beep: running properly, 2 beeps: parity error, 3 beeps: memory read error. These beep codes will change depending on the manufacturer of the motherboard and motherboard types.
