Repairing a motherboard is beyond the skill of most technicians. In most cases, it is cheaper and faster to purchase a new motherboard. You might also need to replace your motherboard to add new features or when you upgrade the processor. Use the following process to install a motherboard:

  1. If you are replacing an existing motherboard, document the current BIOS settings. You might need these settings to configure the new motherboard.
  2. Install the CPU, fan, heatsink, and memory before installing the motherboard in the system case. If necessary, set jumpers and DIP switches to configure devices or enable features.
  3. Add riser screws (also called standoffs) to the system case to match the hole pattern on the motherboard. The standoffs prevent the motherboard circuits from touching the system case.
  4. Insert the faceplate into the case.
  5. Install the motherboard, securing it to the riser screws with plastic washers and screws.
  6. Connect the power and accessory cables.
    • Connect the main motherboard power cable and the CPU power cable.
    • Connect the CPU fan power cable.
    • Consult the motherboard documentation to identify the location for the power switch, hard disk activity light, and other accessory cables.
    • Connect any case fan cables.
  7. If necessary, configure voltage and clock multipliers in the CMOS.
  8. Connect drives to PATA or SATA connectors.
  9. Install additional devices in bus slots.
  10. Connect devices (such as USB or Firewire) to motherboard header pins.
  11. Document the settings of the new motherboard.

Note: When selecting a motherboard, make sure the motherboard and system case use the same form factor.
