New Windows 7 PC crashes to blank screen :(

[Jumpem]

i7 860 + Asus P7P55D Pro + 8GB G.Skill DDR3-1333 C7 + 5870.

The PC will randomly every day or two just go to a blank screen (as in no video output... the PC is still powered on but no output).

I had tried reinstalling Windows 7, running windows update, and installing only the video card driver.

I had run HCI Memtest before and it didn't find any errors. What should I be looking at? Thanks for the help.

What about the sleep setting for the monitor?

I know by default in windows 7 its set to sleep and hibernate after awhile

I've turned it off. I ddon't think it's a sleep bug since it happens while I am actively using the PC.
