I just built a new pc using a AsRock Z77 Extreme 4 motherboard. MSI Frozr III 7950 video card.
It will not boot with the video card in the pc. Using the onboard video i installed windows. I tried both PCi 16 slots and still no boot, just a black screen. Any suggestions on whats causung this. I have an Antec 620W continous PSU
