Last night everything was working fine, but I noticed the video card fan was flying, which it almost never does, especially when I wasn't even doing anything. It's an EVGA 8800GT. This morning, I went to turn it on, and it popped on, then off real fast twice. (it's done this before when an overclock wasn't stable) Then it stayed on, but there was no display at all, no POST display, boot display...nothing. And the video card's fan never went back to normal speed, usually it spins all the way up for a second, then kicks down to normal, but now it just wizzes away at full speed until I turn everything off. I've tried reseating the video card, RAM, took the CMOS battery out for a few minutes, tried a different monitor...nothing. I'm waiting for my brother to get home to ask if I can cannibalize his video card to see if that's the problem. Mobo does not have on-board video, so I can't test it that way. I also get no beeps or anything. Hard drive does spin up with no apparent problems. Ummm, I think that's everything, lol. Any one have any ideas?
