Do you know anybody who might have a spare power supply you could use for testing? If not, I'd call some local PC shops and see if they'll run a quick bench test on it with a known good power supply. Shouldn't take more than a couple minutes. Tell them you'll buy a power supply from them if that turns out to be the source of your problems.
