Power Mac G4 Quicksilver Power light only flashes when you press it.

My Quicksilver worked a few hours ago. I needed to shut it off to go to a party. When I plugged it back in, it would no longer start up and the power light would turn on when I held the button and turned off when released. The fans rattle and that is it. I tried resetting the PMU, reseating the CPU, reseating the RAM and PSU cables, unplugging everything except for the board and the monitor. Nothing worked.
I hope it isn't the power supply because it costs over $100 on eBay which is more than I paid for the computer. If I have to sell an arm and a leg, I would gladly. Any help would be appreciated.

i had the same issue with my QS, turned out one of the hard drives kicked the bucket and was causing the machine to fail to boot. i would say, try unplugging the hard drive power from the hard drives first and see if that makes the mac boot.
