Just upgraded my PC with a new Mainboard and CPU i5 3570k + Asrock Z77Pro4.
Looks like the new mainboard doesn't recognize my GPU (GTX 560Ti), screen stays black if I plug my monitor in it.
iGPU works fine, if I check the device manager under windows there's no sign of my GTX560Ti, just the Intel HD4000.
GPU fans are both running and I already took the card out and put it back in again a couple of times in case it wasn't seated properly but still nothing.
Any idea what could be wrong?
