Windows 7: Page Fault In Nonpaged Area

After more than 100 PFN_LIST_CORRUPT and one Memory Management BSOD, I get this now: Page Fault In Nonpaged Area



What is the cause of this? Here is my dump file

There is only one dump file in your upload and that indicates 0x50 error which points at a memory issue (although could be caused by something else)
BSOD Index
first step would be to run a check on your RAM, i would advise to download and burn memtest and to run in overnight for multiple passes and see what the outcome is
RAM - Test with Memtest86+

Well, I thought that and ran it but didn't show any errors for 7-8 runs. Maybe it can't detect because there are 2 modules??

Have you got any more dumps, upload a few more recent ones if you have them

No. I always get PFN_LIST_CORRUPT and nothing solved it. I could upload more dumps if I get more BSoDs

I got PFN_LIST_CORRUPT BSoD while I was outside and computer was idle (Google Chrome vs were working)

OK this dump lists the error as 0x4e BSOD Index so is likely we are looking at a faulty or non compatible driver, will do some digging and post back later

OK had a better look i cant see any really old drivers on your system however there is a mention of avp.exe which is an element of your anti virus (kaspersky) if so remove it and install MS security essentials as it has good known compatibility with Windows 7

Also if you have done any overclocking stop and return bios to standard settings for the purposes of testing until you get a stable system

If you get any more dumps please post them all

Well, before that, I used ESET but it isn't about it. As I recall, Security Essentials didn't stop it either. I really can't remember.

So what? BSoDs because of antivirus&firewall you say?

No not definately because of it but can cause problems and be a contributing factor (it was listed in your dump file), i would remove all AV and firewalls and just run with MSE and windows built in firewall until you get up and running again
