My suggestion is to carefully check all the capacitors on the
Motherboard to make sure there are no burst one.

The Motherboard I just replaced was flakey. It would work then it
wouldn't. I could boot windows, then I couldn't. It would run for
hours then reboot after only a minute or two of use.

Turns out the MoBo had 11 or 12 burst or bulging capacitors. I guess
it took a power spike somewhere even though it was on UPS with power
conditioning.
