@ROCkY460 -- the three most-likely points of failure are:

1. power supply
2. motherboard
3. processor

It is really expensive to try to replace the motherboard or the processor, and doing so might not fix your computer.

Do you have access to a "multi-meter", to measure the power-outputs from the power-supply, to ensure that it is working correctly?

Take your computer to a computer-store, and have them temporarily connect a different power-supply,, to see if that fixes your problem.
