The motherboard serves as the heart of a computer.
Building and upgrading a computer is something that many people learn do on their own. Motherboards are one of the most important and complicated parts of the computer. Trying to repair any individual part in a computer, especially within the motherboard itself, is far beyond even the average computer technician. Because of the relatively low cost of motherboards and their complexity, the best method of fixing a bad motherboard is to replace it.
Instructions
1. Open your computer case by unscrewing the access door from the back of the case. Check to make sure all of the cables are tight to be sure the problem is with the motherboard.
2. Disconnect all of the cables that are connected to the motherboard. This will include power cables, drive cables and case cables. The power cables should have a tab that needs to be pushed to release the cables. The other cables should pull straight up.
3. Unscrew any cards that are connected to the motherboard and screwed into the back of the case. Lift the cards out. Remove the RAM by pushing the side tabs down lifting it out. Unscrew the CPU fan and heat sink. Disconnect the power from the CPU fan to the motherboard. The heat sink may have to be pinched or removed with pliers. Lift the CPU socket bar up and remove the CPU.
4. Unscrew the motherboard from the case and lift it out. Put the new motherboard in place matching the holes on the board with the case. Put the CPU back in the CPU socket. Match the CPU and the socket holes and pins. One corner will be missing a pin and pinhole.
5. Put the CPU fan and heat sink back in place. Add the memory sticks back in their sockets until they click in place. Reconnect all of the cables.
