Just a thought, good luck!

Good advice. I had an old system whose PSU blew, and took the
motherboard, two hard drive and a bunch of PCI cards with it. The caps
in the PSU were all "pregnant," except the one that blew up.

In many cases that "pregnant" caps are what killed the PSU. The pregnant
caps are often the result of a bad formula that was used to fill them, and
it causes them to swell and/or burst, and they often short out when they
do this.

The first thing I look at, and not just with computers, is the CAPS, and
if they are "pregnant" I don't even go any further - it's just time for a
new board at that point.
