Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn’t crash for you, then let it run for at least 36 hours of continuous operation
How to Disable Driver Verifier:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Delete existing settings" on the first page
I can’t get into Windows
- If you can’t get into Windows because it crashes too soon, try it in Safe Mode.
- If you can’t get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.
- If that doesn’t work, post back and we’ll have to see about fixing the registry entry off-line.
Delete these registry keys to stop Driver Verifier from loading (works in XP, Vista, Win7):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel
Note: If Norton Antivirus is installed, do not enable Driver Verifier’s Deadlock Detection because of the recommendations in Microsoft Knowledge Base article 325672.
