I have been receiving this message a lot when running Revit 2011 on a Dell Latitude with 8gigs of ram, Windows & (64bit) and a Nvidia v3100m graphics card.
Display Driver Nvidia Windows Kernel Mode Driver Version xxx.xx stopped responding and has successfully recovered
What normally happens, is that I will be happily working away in Revit 2011 then suddenly the screen with go black; a little disconcerting; next a message box will appear in the bottom left had corner of the screen with the above message. Revit doesn’t crash, but you do notice that the graphics will be rather sluggish. A save and restart of Revit resolves the problem. It would seem that this crash is as intended, even though very annoying, this statement refers to something called a TDR. A TDR or Timeout Detection and Recovery is a feature that attempts to detect problematic situations and recover to a functional desktop automatically. This feature first appeared in Windows Vista, but it tries to keep the OS going without freezing the PC and forcing a restart.
One issue is that this particularly laptop does not have certified graphic card drivers, it certainly doesn't appear on the Autodesk graphic card list. I have tried drivers from the Nvidia website, but this hasn’t helped. So after a bit of digging around on the internet last night, it was suggested that if you turned off the Windows 7 icandy and actually run in Windows classic mode it would stop the issue. I have been trying this for the 12 hours now and so far……the issue hasn’t returned.
