0x00000050 "page fault in non paged area"

Icoris · 27 Jun 2013

Unfortunately this isn't my first time posting in these forums, I really hate BSODs.
Attached are my dump files. A little bit of a background on what's going on, a couple months ago, had a faulty ram problem, no blue screen, comp just wouldn't turn on, finally got new ram 3 weeks ago. Everything has been running fine. Then I come home to a "page fault in non paged area" loop.

I can get into safe mode fine. I get an error trying to retrieve minidump files though. I've followed the instructions in the dump files thread, and it does say recording dump files when the BSOD is happening and the latest .dmp file has been included in the zip. Let me know if I'm missing anything.

Also, when I do a system restore, my comp is back to working order temporarily, but when I restart, back to BSOD.

The BSOD is caused by avast! Self Protection Driver.

Description here: Driver Reference Table - aswSP.SYS

Uninstall Avast using Avast Uninstall Utility. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Install Service pack 1 and all other windows updates. Otherwise the system will remain vulnerable to threats.

Figured this out just as you posted as well, by using the blue screen viewer and some quick googling. Restarted and all seems well so far, I've uninstalled in safe mode from remove programs screen, I'm assuming that should suffice. MBAM currently installed as well. Should I do a quick runover with avast uninstall as well?

Go for it.

And dont forget the SP1. It is the question of security and stability.
