KB #: KB58633 talks about same issue.
Sorry, but #: KB58633 is not the same issue:
There is Event ID: 10001 / 10004 and I have a problem with EventID 10010.
Even the solution from #: KB58633 doesn`t work.
In some cases this is caused by graphics card drivers. Are all these notebooks same dell model?
Can you try to upgrade this driver or roll it back if you have updated it?
Yep, these notebooks are DELL Latitude D630 64-bit.
Uninstalling this dell nVidia 179.68 Vista64, A07 6/18/2009 driver and installing windows standard VGA driver seems to solve this problem.
