Windows 7: Sudden start of frequent BSODs with only browser opened

Hi , few months ago i had a problem with constant BSODs , reporting the same error as these now : "page fault in non paged area" . I reinstalled windows and had no problems since , until today.

I got the bsods while not even doing anything , just having Mozilla open.

Here are the additional details about the problem i got from windows when i started up the computer :



BCCode: 50
BCP1: FFFFF8A00B966000
BCP2: 0000000000000000
BCP3: FFFFF80002F99079
BCP4: 0000000000000000
OS Version: 6_1_7600
Service Pack: 0_0
Product: 256_1

I also attached the SF diagnostic tool folder with the kernel memory dump (i think) since that was on by default.
Any help would be very much appreciated.

Welcome

STOP 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA BSOD Index

Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

Please uninstall Avira antivirus.
Download and install MSE, run a full scan once installed and updated.
Microsoft Security Essentials - Free Antivirus for Windows

You need to update your BIOS.
Its way too old!

Run disk check to make sure your hard drive is good.
Disk Check

Run the system file checker to repair any corrupted windows file.
SFC /SCANNOW Command - System File Checker

Forgot to mention: Get all updates from windows updates including SP1!

Observe your computer after doing these and post more dumps if you get them.

Ok so , i uninstalled Avira and rebooted , and right after that i get another BSOD.
I ran the disk check , reported no errors. Same with the system file check.

Somehow i don't think it's anything BIOS or system update related , since it starts like this all of a sudden . I had no problems for a few months since i reinstalled the windows , and i haven't made any driver changes nor changed any hardware...

Also , i always seem to get that same error. I was once told that could be cause of faulty RAM memory , but i ran a lot of tests and at the end it seemed that wasn't the problem after all.

I don't really know much about this subject , but i fail to understand how and why do these BSODs start happening.. Last time i had them it seemed unfixable , yet i managed to solve it by just reinstalling. But still , at that time i had a lot of leftovers of some anti virus softwares , a lot of driver issues and a lot of other things. But this time i really haven't done or changed anything for probably over a month and yet it just randomly happened once , and now i get one like every 30 minutes when I'm on the computer.

Anyway , thanks for the response. Is there maybe something else i could try?
