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.
