I've been talking to tech support from XFX, but they've yet to come up with a solution
Hi, did you solve your problem ? I have similar problems but on Windows 7, and before on windows XP.
I use XFX 285 GTX, befor e8800 GTS, never any problems.
I run on few years old PC, AMD 3200+ CPU, SATA raid, AN8 SLI m/b
