Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

   Information

What is Driver Verifier:
It puts stress on the drivers, and tries to make the faulty driver crash the computer. It is designed this way, to attempt to trap the offending driver.

What you will notice:
It will tend to make the computer rather slow and sluggish because the drivers are being stressed.

   Warning

Before enabling DV, make sure you have created a system restore point before enabling Driver Verifier. make a System Restore Point manually before enabling DV.

   Tip

• If you fail to get on the Desktop because of DV, Boot into Advanced Boot Options > Safe mode. Disable DV there. Now boot normally again, and try following the instruction of enabling DV again.
• If you cannot boot in Safe mode, do a System Restore to a point you made earlier.

Let us know the results, with the subsequent crash dumps, if any.

It should not disappear, unless you deleted the whole folder. It is the folder that holds your graphics drivers. It can't disappear.

Look in program files.
