Hello,
Please review the following to isolate and resolve this issue:
Driver Verifier (verifier.exe) is a diagnostic tool that is included with Windows XP, 2000, and 2003. The utility is primarily used to troubleshoot issues with improperly written drivers. If this feature is enabled on a machine, it will usually cause the machine to blue screen if any drivers are found to be not digitally signed. The Backup Exec tape device drivers, robotic library support and Advanced Open File Option (VSP.SYS) are all drivers that are not digitally signed. Because of this, Symantec does not recommend having this option enabled on production or business critical machines that have either the Advanced Open File Option or the Backup Exec Device Drivers installed. If the option has been enabled and a machine bluescreens because of it, perform the following steps to boot up in a normal operating mode:
