BSOD When Switching Users or Logging out

[plfoss]

Hello,
I have been experiencing random BSOD crashes when switching users or logging out.
This happens about 1 out of 4 times.
What I have done so far:
Applied all Windows Updates.
Updated Video Drivers.
Updated some mother board drivers from Intel.
Run x86 memory scan - No errors
Run chkdisk - No errors.
Virus scan using MS Security Essentials. - No hits.
Malware scan using free Malware bytes. - No hits.
Remove all Cyberware software (I saw this in another post).

This particular BSOD has become a real problem because I am testing software that requires multiple account
types.

Thanks for any help you can provide.
-Paul
