Here are the steps required to install a motherboard properly:
Step 1: First thing to do is to install the faceplate. The faceplate or I/O shield is a metal plate that comes with the computer case and fits over the ports to create a well-fitting enclosure for them. A case might have several faceplates designed for several types of motherboards. Select the correct one and discard the others. Insert the faceplate in the hole at the back of the case.
Step 2: Install the standoffs. Standoffs, also called Spacers, are round plastic or metal pegs that separate the motherboard form the case, so that components on the back of the motherboard do not touch the case. Make sure the locations of the standoffs match the screw holes on the motherboard. If you need to remove a standoff to move it to a new slot, needle-nose pliers work well to unscrew or unplug the standoff. The case will have more holes than you need to support several types of motherboards.
Step 3: Place the motherboard inside the case and use screws to attach it to the case. There should be at least six standoff/screw sets, and there might be as many as nine. Use as many screws as there are holes in the motherboard.
Step 4: Connect the power cord from the power supply to the p1 power connection on the motherboard.
Step 5: Connect the 4-pin auxiliary power cord coming from the power supply to the motherboard.
Step 6: Connect the wire leads from the front panel of the case to the motherboard. These are the wires for the switches and lights on the front of the computer. Because your case and your motherboard might not have been made by the same manufacturer, you need to pay close attention to the source of the wires to determine where they connect on the motherboard.
Step 7: To know which wire connects to which pins, see the motherboard documentation or look for cryptic labels imprinted on the motherboard near the banks of pins. Sometimes the motherboard
