This is also caused by your display driver & not the graphics driver. The problem is that when you dump (or it should auto dump) is that the files are only getting partially dumped & pieces are left behind. This will cause errors. if this patch does not work the you have to go into the mini dump setting & change them (making a copy of the records before dump & post on here so I (we) can see what is locking up & causing the crash. ntoskrnl.exe is not the whole problem either a .dll or .dat is euchred & causing this problem.

Another option is to totaly remove & look for updated display driver & adapter driver (these are different then graphics driver's & are on microsoft's website most likely). I would also suggest to clean the registry before installing the new drivers & any left overs. There will be shared .dll's that will prompt you when uninstalling. You should remove them but since only the display is crashing it would be safe to assume it is none of these .dll's
