    Very likely could be motherboard though but I have had the same thing solved by replacing PSU.
  2. in your opinion, would a bad PSU continue to function properly while actively using the computer? am trying to eliminate possible causes: faulty start button, mobo, or psu. thanks.

    Yes, it was the power supply, though when I explained it, they thought it was something else. Had a new PS installed since way too complicated for me to install. Was told will lengthen life of power supply if I power off computer every night instead of leaving it in Hibernation mode...
