Sorry for the late reply! I tried changing my RAM slots. That didn't help. Its a server with 5 hard disks configured in RAID 5.
The problem occurs when ever I execute VB stand-alone application. Soon after 3-4 seconds the page fault in non-paged area screen appears.
If there is any solution to it or any information you may need please help.
I do not want to format my server just because of this issue.
Note: There's a need of opening VB application.
