STEPS IN BUILDING A COMPUTER PART 1

 NOTE: Assemble the motherboard before placing it into the case

1. Align the CPU pin 1 with the socket pin 1. Look for a dot on the CPU and a triangle on the socket to indicate pin 1. Check the CPU and motherboard documentation to ensure alignment. Place the CPU gently into the socket. Never force the CPU into its socket, as excessive force can easily damage the CPU and the socket. Stop if you encounter any resistance and make sure that you have aligned the CPU properly.
2. Secure the CPU to the socket on the motherboard with a latch plate. Close the CPU latch plate.
3. Secure the latch plate in place by closing the load lever
4. Secure the load lever under the load lever retention tab
5. Apply thermal compound to the CPU. Thermal compound helps to conduct heat away from the CPU. In most cases, only a very small amount of thermal compound is required. The compound spreads out evenly under the weight and pressure of the heatsink and fan assembly. Follow the application instructions provided by the manufacturer of the thermal compound. Use no more than a grain of rice.
6. Align the heatsink and fan assembly retainers with the holes on the motherboard and place assembly onto the CPU socket,. Avoid pinching the CPU fan wires
7. Tighten the assembly retainers to secure the assembly in place. Follow the instructions from the heatsink and fan assembly manufacturer carefully.
