Check for bad caps on the motherboard. These are the usually blue or
black plastic covered post like things that stick up vertically from the
motherboard. The tops should be flat, if any of them have bulged or
have leaked, those are the bad caps and are the cause of the problem.

It isnt generally practical to do anything more than
replace the motherboard if that is the problem.
