My ASROCK Z75 Pro 3 won't detect my GPU (MSI R7850 Twin Frozr). Everything shows up in the BIOS except for the graphics card, and it doesn't show up in device manager either. I've installed all the possible drivers I can, I've tried to update the BIOS, I've tried the graphics card in both PCI-E slots and I've tried my friend's graphics card as well, and it did not show up either. I've been trying to fix this for nearly 10 hours and don't know what else to do...Everything works fine, except for the graphics card. Is the PCI-e bus bad on the Motherboard, or am I missing something simple?
