Drivers I tried:
306.23: Full screen works fine. windowed mode hard locks
310.90: same as above
314.07: Doesn't even work in full screen. Get instant BSOD when starting games.
Core 2 Quad Q9450 @ stock
EVGA GTX 275 896mb + GTX 275 SC 1792mb
Asus P5Q Pro Turbo mb latest BIOS
Windows 7 Pro 64-bit
WRONG INFO HERE:
It is not HyperSLI related. You cannot use SLI in window mode.
Thats why the freeze/hard lock
Also, some games after you start them, will start in window mode then go to full screen mode (really fast, barely noticeable by us), SLI doesn't like that and will crash the system.
YOU CAN USE SLI IN WINDOW MODE.
