Computer won't POST

[BornStar]

We had a power failure yesterday but my UPS carried me through it. After about 5 minutes I decided to shut down my computer (my monitor was on a different UPS and had already lost power) so I pushed the power button to initiate the shutdown sequence in XP and then I shut off power to the UPS to stop the beeping after the computer had shut off. Anyway, I forgot about my computer until today so I turned the power on to the UPS and then turned the computer on and walked away. Ten minutes later I came back to it and and found the monitor off and nothing happening with the system so I pushed the power button to turn it off again but nothing happened this time. Then I held the power button for at least ten seconds and it still didn't shut the computer off so I had to switch the PSU off. I've tried disconnecting the drives, clearing the CMOS, and changing the PSU but nothing fixes it. The computer turns on, the fans, HDDs, and optical drives spin up and then nothing happens.

Athlon 64 3200+
Gigabyte 6100/430
1GB OCZ PC3200
36GB Raptor
Samsung and NEC opticals
Antec TPII 380W and Aspire 410W
using integrated video

Does anyone have any ideas?

your monitor that was on the other ups, what became of that? did you ever turn that ups on and see if that monitor's power light came on?

Have you tried bypassing the UPS's?

Yes. When I unplug the monitor from the computer it kicks on and says it can't find a connection.

Yes. I had the computer in the kitchen to work on and had it plugged directly into the wall.

edit: a little tired when I wrote that.

Well, I looked around on Newegg and it appears that everyone is having problems with Gigabyte nForce 430 boards not booting after a power loss. Looks like I'm going to be going with a different board. I might RMA this one but just as a backup for the future.
