I have a Core i5 760, 16GB ram, HD7950, Corsair HX750 PSU and Win7 Ultimate x64 SP1. Before the HD7950 I had a NV GTX 295 and before that a HD4870 on the same machine. The previous two were stable under the same Power Management settings.
The driver I have is amd_radeon_hd7900_win7_64.exe (137,171,160 bytes) - 8.921.2 RC11 AMD Radeon™ HD 7900 driver.
My power management settings are turn nothing off ever except for the display at 15 minutes. I also have a screensaver of blank set for 10 minutes and require login when leaving screen saver.
Since the HD7950, if the monitor switches off, the computer becomes completely unresponsive. I can't ping it from another machine and mouse and keyboard don't wake up the display.
This error appears in Event log:
Session "Microsoft-Windows-Setup" stopped due to the following error: 0xC000000D
Thanks in advance!
