Hey guys. I have been getting this error lately. I have to restart the pc and then do a system restore to get back into windows. Here is the Action center print out: Source Windows Summary Video hardware error Date 15/01/2011 15:54 Status Solution available Description A problem with your video hardware caused Windows to stop working correctly.

Id just like to find out wheter or not its software or hardware. I have cleaned the nvidia drivers and installed the latest and this problem still occurs. I am also running windows 7 professional 64bit. Any help would be great, Dan.
