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.

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?
