The conclusion 'Critical process terminated' isn't very useful information to me either!
Unfortunately from what I have read it can be very difficult to track down the cause of this error.
In Safe Mode, have a look in the Event Viewer
for any errors at the time of the BSOD
To open the Event Viewer go to Start
> Control Panel
> Administrative Tools
> Event Viewer
. Alternately, go to Start
and type in "eventvwr.msc" (without the quotes) and press Enter.
Check in all the categories.
If you find an error that occurred at the time right-click on it and select properties. Copy the information in the window and post it back here.How To Use the Event Viewer
