Probably lots of typical lurkers like myself that read them anticipating a nugget that will help us solve the issue, but don't bother to post. I've been wrestling with this on the 5770 I got in a new CyberPowerPC machine I received two months ago, and have had it. No official word anywhere, and no end in sight to this problem. In the past my gray screen/vertical stripe crashes only happened in 3D intensive games. For the first time today I got a white screen crash/driver auto-reset from the 2D desktop. Seems to be getting worse over time, lending credence to the degrading part hardware problem theory. Starting the RMA process tomorrow.
