Hello guys, I have just purchased a i7 2600k to run with my 7970 and I have bought the gigabyte motherboard z68x-ud3h-b3 motherboard. I was using my gpu fine on my old build and old motherboard but this new pc setup doesn't even pick up the gpu, I'm device manager the gpu doesn't show and I've even tried disabling the onboard graphics also. I've tried both pcie slots that are on the board and nothing. Surely both pcie's can't be bust?!?
Check to see if your system detects the GPU in bios.
I've had this issue a few times where the card simply wasn't seated properly, or I forgot to connect the PCI-E power cables, and thought it was a Windows issue until I realized I just made a simple mistake.
*update* the card works with my old motherboard and the same psu that I'm using, could the cpu be the problem? It is working perfectly though so not too sure. Everything is pointing to the motherboard being the main issue
If the card works fine on other systems, and the current system can run another card just fine, then the issue is likely either that your PSU isn't providing enough power or that something isn't connected properly.
Check if your mobo has additional power connectors that need to be powered in order to run the card.
