I have just upgraded My CPU from a AMD Athlon 64 3800+ to a AMD Athlon 64 X2 4400+ and this causes My graphics card to become disabled. I have switched back to the 3800+ and everything is fine again. I thought it was the processor so I exchanged it and I am having the same issue. The specific error for my Graphics card is "Windows has stopped this device because it has reported problems. (Code 43)" I have uninstalled and reinstalled the Drivers for the Graphics card and Have updated the Bios to the latest version. I have a 500watt PSU so that should not be a problem either.
Here are my Specs:
