I just finished my first PC build. I used memtest and it found no errors, I didn't use prime 95 for a full test yet but it was going fine. However, when I try to run furmark for the GPUs I get a blackscreen after only a few seconds. A message pops up saying that the graphics driver timed out but it doesn't offer any fixes beyond reducing the resolution.
Specs:
AsRock Z77 extreme9

32Gb dual channel DDR3 1600
2x EVGA Geforce 660Ti

Windows 7 pro 64-bit
All stock settings, and I have installed the latest drivers.
