So I just built a new computer, double-checked to make sure everything was compatible. It's an ASUS P8B75-V motherboard with an EVGA GTX 660 graphics card. If I plug my monitor into the graphics card, I get nothing. No signal at all. If I plug it into the Motherboard, I get video through the integrated graphics.
Here's were things start getting weird. When I first assembled the computer, the card worked amazingly well until Windows 7 went into hibernation. After that, no matter how many times I rebooted it, unplugged the computer / PSU, told the BIOS to use the PCIe slot instead of the integrated graphics, it simply refused to recognize my graphics card, even though there's definitely power going to it, seeing as the fan's running.
My PSU at the time was a 450W that came with my case, so my first assumption was that it was insufficient. I upgraded it with a Thermaltake 600W unit which, by all indications, is overkill. Booted it up, graphics card worked like a dream... Until my computer went to sleep, which started the problem up all over again. For the sake of experimentation, I simulated swapping out the PSU again by basically unplugging everything and plugging it all back in. Still no love, my BIOS flat out won't use anything other than the integrated graphics. I even went so far as to update my BIOS. To make things even stranger, my old 9600GT works perfectly fine in the same PCIe slot. I'm utterly stumped.
To sum up, here's the problem: Graphics card worked for a bit, computer fell asleep, and now it will not be recognized by the motherboard. This scenario has been duplicated once.
Here's what I've tried:
Searching for the graphics card using Windows's Device Manager (Win7 64-bit)
Rebooting
Making sure everything's plugged in
Updating my BIOS
Unplugging and replugging everything
Disabling integrated graphics via BIOS
Updating my drivers
Instructing BIOS to use PCIe
Upgrading PSU
Testing PSU (I have a tool specifically for this task)
I'm going to try exchanging my card for an equivalent one tomorrow, but if there's a fix that doesn't involve waiting six days for a box to come in the mail, I'm all ears.
