If you are having problems with lockups, blue screens, or can only get to safe mode,
often the problem is due to a faulty device driver.

One way to help identify them is through the use of the Verfier program
Start / Run / Verifier
Keep the default of Create Standard Settings
Select the type of drivers you want to confirm
A list of drivers to be verified on the next boot will be shown.
Reboot
If your computer stops with a blue screen, you should get an error message with the problem driver
To turn off the Verifier, run verifier /reset
