As computers become more reliable, the need for major hardware repairs becomes less likely. However, power surges, lightning strikes and overheating can still cause component failure in desktop computers, which could lead to motherboard replacement. Airflow is important to keep the interior of the case cool as well, and the build-up of dust on the computer's motherboard can decrease the case fan's ability to keep things cool and lead to component failure. The need to improve a computer's performance can also be a reason for upgrading a motherboard, and the steps are the same as replacing one that has failed.
Instructions
1. Disconnect the cables and connectors from the computer and lay them on a flat work surface. Remove the side of the case that allows access to the inside of the computer. Inspect the inside of the case to make note of the cable connections and placement. Attach the anti-static wrist strap to your wrist and the metal frame of the computer's case. Use canned air to blow out any dust build-up from the inside of the case.
2. Remove the power supply connectors from the motherboard and other components such as the hard drives and CD drives. Lay the cables out of the way of the case opening. Remove any fan shrouds and the memory from the old motherboard. Disconnect any case fan connectors, case-mounted USB connectors or card reader connector cables. Carefully remove the fan and heat sink from the top of the processor. Remove the processor very carefully by releasing the retainer and lifting it free by the edges. Avoid touching the pins on the underside of the processor.
3. Make detailed notes on the placement, order and color of the computer's front panel connectors, which feed the power switch, power and hard drive lights, and reset switch. Note which color was installed to which pins and which order the colored wires were in. Remove the front panel connectors from the motherboard.
4. Remove the retaining screws around the outside edge of the motherboard. Remove any additional screws from the interior of the board as well. Gently lift the inner edge of the board and pull it away from the rear of the case to free the keyboard, mouse and monitor connectors from the back panel. Set the board aside and clean any dust or debris from the empty case.
5. Reinstall the motherboard into the case and reinstall the retaining screws. Install the processor, heat sink and fan into the new motherboard. Reinstall the memory, case fan and power supply connectors. Reconnect any USB and card reader connections. Reinstall the front panel connectors using your notes to ensure the placement and order are correct.
6. Reinstall the side panel, and reconnect the computer to your monitor, keyboard and mouse. Start the computer and verify the new board functions correctly. Install any needed driver and program updates from the computer or motherboard manufacturer's website, or from any CDs provided with the new motherboard.
