If you see the device in the Device Manager that means you should be able to use it. However if the mobo cannot send graphic signal to every graphic card plugged in by a user and must decide to send the signal to only one device then the Device Manager should not report the unused hardware because the BIOS would not hand that information to the OS. GPUs: EVGA GTX 560 Ti and MSI Radeon 6850ĮDIT: I haven't tried disabling on-board graphics yet (just made sure PCIe was the priority), because if that doesn't fix it, then I won't have any display and will have to reset the mobo (last resort). Am I missing some sort of motherboard software or is it a compatibility issue? I'm really at a loss here. I don't think the slots are dead because neither PCIe slot works.

I tried installing Nvidia/ATI drivers, but they won't even install because I don't have the proper hardware (card not detected) Tried the PCIe x4 slot, it doesn't detect them The option for primary display is reset in the BIOS back to "Auto select" after this. Going into the BIOS, selecting primary display as PEG (which is the PCIe slot), it saves, I plug in a monitor to my GPU, nothing, but I plug the monitor into the on-board graphics and it works. updating Windows, including all optional updates two different graphics cards (560 Ti and 6850) There is no indication of a graphics card in Device Manager. I can't get my PC to detect any graphics card despite plugging them into the PCIe x16 slot (closest to the CPU) and their fans coming on. I replaced the motherboard now, installed Windows 7 again (but kept the old files on the HDD, as custom install lets you do, it just partitions the drive), and only the on board graphics is working. I took it to a computer repair shop and they determined it was the motherboard. So, I had a power outage and my PC wouldn't start up afterward.
