also there was this fix for registry thang "Display driver stopped responding and has recovered" error in Windows 7 or Windows Vista

Let me fix it myself

Exit all Windows based programs.
Click Start, type regedit in the Search box, and then double-click regedit.exe from the results above. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Browse to and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
On the Edit menu, click New, and then select the following registry value from the drop-down menu specific to your version of Windows (32 bit, or 64 bit):

For 32 bit Windows
Select DWORD (32-bit) value.
Type TdrDelay as the Name and click Enter.
Double-click TdrDelay and add 8 for the Value data and click OK.

For 64 bit Windows

Select QWORD (64-bit) value.
Type TdrDelay as the Name and click Enter.
Double-click TdrDelay and add 8 for the Value data and clickOK.
Close the registry editor and then restart your computer for the changes to take affect.
If this method did not resolve the issue, continue to method 2.
