If you have tried all of the troubleshooting steps above and you are still having problems, then it is likely that your motherboard is dying and you will need to replace it.

Here are some specific things you can look for when trying to diagnose a dying motherboard:

Burn marks or discoloration. These can be a sign of overheating or electrical damage.

Loose or damaged components. Make sure all of the components on the motherboard are properly seated and not damaged.

Corrosion or rust. This can be a sign of water damage.

Bad capacitors. Capacitors are small cylindrical devices that store electrical charge. If they go bad, they can cause a variety of problems with the motherboard.

Bent or broken pins. The pins on the motherboard are used to connect it to other components. If they are bent or broken, it can cause problems with communication between the motherboard and other components.
