Came home for spring break, tried turning on my desktop and the lights light up, then shut off. The fans begin to spin, then shut down. Pause for a second. Then lights go back on, fans spin up, only to shut down. Repeat ad nauseum.

Opened case, no burning smell, motherboard looks ok, PSU looks OK (warranty already passed so I opened it up), all connections are set but the thing won't boot. PSU was a crappy 430W (says that on the sticker, but yeah right...) mini atx thing that came with the case. Most reviews said the included PSU was poor, but it's lasted me a good 2 years so I don't think I can really complain much.

I'm thinking 99% it's the PSU that's gone, but if you can think of any reasons before I go and buy a new PSU tomorrow, I'd like to hear them.

got another desktop to borrow a PSU from to verify it? how long are you on break for? i get home on wed-ish, i could help you if you want.

There's one more desktop upstairs but it's our only other one and I don't want to be responsible for an accident that kills the remaining computer left in the house.

Do some research on the web. There is a way to get the power supply to power on by jumpering two of the contacts and then use a multimeter to test the voltage on each pin.

its the one green wire to any black wire. then test each pin with any black and what ever color.

Uh, well a new PSU is on its way already, so if it ends up not working, I'll be out $22.

Anyway, the new PSU arrived, I swapped it in (with a little difficulty as the old PSU was specially designed for this case) and voila, I'm back in business.
