Alright, I can't figure out what's going on here. When I came home the other night (I'd left my computer on), there was no video signal to the monitor. I restarted manually and the CPU fan spun loud and very fast for a few seconds before reverting to a normal speed, but there was still no video output (tried both DVI ports plus S-video). I heard the Windows music, though, so I knew the computer booted. I switched from my video card to the integrated VGA hookup and got a working signal from that.

This made me thought the video card was fried, but considering the issue with the CPU fan, I'm not so sure. I'm not too techy, so I don't know what else to check/try. Please help!

Specs (let me know if I'm excluding anything important) -

Dell Dimension 4700 running XP
CPU: Intel Pentium 4 530 3.0Ghz
RAM: 2GB DDRII
GPU: Nvidia Geforce 6800GT PCI-E
Mobo: Dell 0M3918
PSU: Antec Truepower 2.0 550W (dual fan version)

try the card in another computer to check it
if it's ok then your psu is probably no longer supplying enough power on the 12v+ to run it
see wha the bios lists it's output at

thanks for the suggestions! unfortunately, the bios doesn't list voltages/temps (thanks, dell) and i had no luck with a couple different diagnostic programs (speedfan, etc.). any other way to check psu output, short of getting a volt meter? and since i don't have another machine to try the video card in, i'll probably have to take it to a store and pay for a quick test. ah well...hopefully i can just replace one of the two and i'll be back up and running.

any other suggestions are very welcome!
