I've been running my system for about 6 months now without issue, but yesterday the peripherals froze for no apparent reason, and when I rebooted it, I couldn't even get a post to show; all the fans and lights would turn on, but nothing would appear on the screen.
Here's the system:
P4 3.0GHz HT (Northwood)
ASUS P4P800 SE
ATI Radeon 9800 Pro 256
WD 200GB SATA
Soundblaster Audigy ZS
420W PSU
As I mentioned, there were zero problems with this system before, and between the last time it last worked and when it died, I changed and touched nothing. When it didn't boot up, I hooked up the monitor to another computer, it ran fine. Took out the video card, put in a radeon 9200 (which worked fine on the computer I took it from) and no change. Put my video card in the other computer and it worked fine. Moved the sound card over - worked fine. Changed PSU and hooked my PSU up to other computer - changed nothing on mine, worked fine on the other. Disconnected everything except the video card, monitor, CPU, and PSU and still nothing when I start it up. So I've pretty much eliminated everything but the mobo and perhaps CPU, but even if the CPU were shot, I should get a startup post, but still nothing. The light on the monitor remains orange, as in the case where it's connected but getting no information. Additionally, my keyboard doesn't work (hooked up to USB on mobo). The fans all activate, and the power button works, so what could be the problem? I searched the forum for similar issues and I tried removing the battery (I think that's equivalent to a CMOS reset?) and I'm not sure what a "lazy" screw is, but the mobo seems firmly attached to the case, as it always has been...
At this point I'm at a loss as to what the problem could be. I'm fully prepared to accept a dead mobo and just get another, but I don't really believe such a new mobo would just die spontaneously, so if there's a possible fix I'd like to try it. Any help is appreciated!
