Ok, brand new build P8P67 Pro (Rev 3) initially boots up fine and I install windows. The next day I get no output to monitor with my MSI 6950 Twin Frozr, also motherboard is beeping to indicate no VGA detected. Put it in second PCI-E slot and bingo, it works but it's at 8x.
Presume mobo faulty, got an MSI Z68A GD65, I get the exact same problem, won't show anything in primary slot but will run fine in secondary at 8x.
I really don't understand what the problem could be if not the graphics card in this case.
Any advice would be apprecaited.
Rest of the spec:
i5 2600k (stock speed)
Corsair TX 650,
Kingston HyperX Genesis Grey 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz.
