I've had a couple desktop psu's fail. symptoms have been intermittent hard-locks, out-of-spec voltages, difficulty when rebooting (such as power leds come on, but no POST) etc. Nothing definitive, but the problems have gone away with a new power supply. My understanding is that psu's are the most failure prone item in a computer. I always consider them first if I'm having any sort of difficult-to-diagnose problem. .02 A
