Have another PC somewhere that you can swap power supplies with? That will tell you. Intermittents are the worst things to diagnose. It could be something shorting out somewhere, but probably the power supply. I'm an EE and I design power supplies, but I don't fix PC ones. I hate to tell you this, but a 13 year old PC doesn't owe you anything, just sayin'. Get a new motherboard and power supply and stick it in that cool case.
