I posted earlier about this but I feel the description of my problem was sub-par. So I'll give it another go. A few weeks ago, I turned on my computer, which started up fine, but the monitor wasn't receiving a signal (I got the "No Signal" message on the screen, and then the monitor went to sleep). So, I unplugged the DVI cable from the computer, and I unplugged the power to the monitor, waited a few minutes, plugged everything back in, and it worked fine.
About a week ago, it did the exact same thing again, except this time, unplugging the cables did nothing. I took out the video card (GeForce 7500LE), blew the dust out of the fan, and reseated it. Still, same problem. To make sure the computer was working fine, I used the TV-Out port (on the motherboard) and connected the computer to the TV. Everything looked fine, it booted into Windows XP and everything.
So, I suspected the card was shot. I bought a new e-GeForce 8600GT (EVGA) and popped it in. Still, same issue, no signal to the monitor. I made sure I deleted all the old drivers before trying to install the new ones, but still nothing. Windows even recognized that new hardware was installed, so I don't think the PCI-E port is busted. I reseated the RAM, I reset the CMOS, everything. After messing with it, Windows started acting funny, and I was desperate, so I backed everything up, wiped the hard drive and reinstalled windows. Neither video card works, even with the new windows install.
I'm at a loss for how to fix this. I don't have onboard video on the motherboard (unless that S-Video TV-out port counts) and I didn't see any option in BIOS to disable it. I don't get any system beeps at post. It's a 32bit machine.
I should also mention that I tried the monitor on a different machine, and it works fine. I also tried a different monitor on the broken machine, and it did the same thing.
Any help would be ENORMOUSLY appreciated.
