BSOD Errors - 0x0000005 What gives

[xfile102]

I have looked this up all over the web, but cannot find a cause.. My moms PC was working great and then this week, suddenly is has had random BSOD's. Always 0x000005 ERROR IN A NONPAGE AREA. I have run memtest, no errors, chkdsk and sfc, no errors. The system creates DMP files, but I do not know how to read them.

This link - http://msdn.microsoft.com/en-us/library/ms854882.aspx - gives more detail on the error. When you ran chkdsk did you use any switches such a "chkdks /f /r" or did you just run chkdsk?

What anti-virus software are you using?
After using BlueScreenView this is what I found:
Bug Check String: PAGE_FAULT_IN_NONPAGED_AREA
Bug Check Code: 0x00000050
Caused by driver: tcpip.sys
From what I could gather through a search it could be related to your anti-virus program/firewall.
