BSOD when starting up using Driver Verifier

Driver verifier is supposed to cause BSODs. Is there any reason that you enabled it? If your previous BSODs lead you to do it, disable DV.

Uninstall BitDefender. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Let us know for any further BSOD, obviously without DV. If it is needed, you will be suggested for it at teh proper time.
