I turned my computer off the other night and the next day when I tried to turn it in, the monitor was showing that it had no signal coming from the computer. Normally when that happens, one would assume the video card or the cable to the monitor. I tried another cable to the monitor and tried a different monitor and neither of them showed any video. I went and bought a new video card today, popped that bad boy in and still am not receiving any video. Anyone have any clue on what else it could be other than the motherboard being the problem?

No signal issues are rarely the graphics card, cable or monitor.

Does the PC power on at all?

First thing to try would be another PSU, then another mobo.

ya computer turns on fine. I didn't notice before now, but when I turn it on the HD light stays red for a minute then just turns off completely, no green light at all... so it might be that.

but as far as the actual computer goes, it stays on the whole time.

Either PSU or mobo IMO.

PSU being the cheapest to try first.

try clearing the CMOS manually (using jumpers) go to your mobs manufactorers website to find out how. It maybe trying to boot into an onboard video output that isnt there or not plugged in. also make sure that it is powered properly some motherboards has reserve power intakes for their PCI-E slots. (usually just a molex). I take it you didnt try to overclock anything before you turned your PC off.

To be honest, I think I'm going to second Dave on his diag. If no major changes have been done to the system and all of a sudden there is a problem like that occuring, than it smells like some hadware failure. In this case, it sounds like the PSU is simply not supplying enough juice to keep the system running so swapping out the PSU might be a good start in determining where the problem could be.
