BSOD at random moments, latest error 0x0000003b

Hey :)

Lately i have been getting bsod fx. when i use firefox and a VPN program. Then suddenly the pc crashes. Sometimes also just using firefox, and no VPN.

Other times i have gotten bsod when gaming, fx. age of empires.

I have tried different drivers, different OS system (win 7 ultimate, win 10 ect.) but, i keep getting bsod at times. So i was wondering if anyone of you might be able to see if it is a hardware specific problem, or a software problem. Any help would be welcomed :)

(I have attached my latest 2 dump files)

While waiting for a member to check the dump file, can you find the time to run MemTest?

After you boot from the usb with MemTest, press:

(c) Configuration
(2) Address Range
(3) Test All Memory
(0) Continue

Did you try uninstalling then reinstalling Firefox? Also, disable all of your your Firefox add-ons, to see if the crashing stops. If it does, then re-enable one add-on at a time, then wait a bit, to see if you can identify which one might be crashing the computer.
