Sounds like a shorting or power-good issue to me. Try pulling your system out of its case and running it barebones with only what you need to power up. If it's still happening, then it'd probably be a powergood signal issue. Dunno much about how that is determined by the supply itself, however, so you're best bet would be to get a new supply. Hey Gee, do you have any insight into how powergood is determined and signaled by the supply and how the motherboard uses that info?
