BSOD While Playing Black Ops 2

I built my PC about a year and a half and lately It seems to be blue screening a lot it was rare it would happen before It mainly does it after playing Black ops 2 for a couple of hours it's not overheating its rare my cpu goes over 50 and my gpu over 60 so I have no idea what is causing it.

I have checked all my drivers are updated and reinstalled windows and it still happens I have used windows memory diaganostic tool and it comes up clear I don't know what is causing it I only have one antivirus which is microsoft security essentails I did use avast before I reinstalled windows but in an attempt to stop the blue screens I thought I would change to MSE.

The last two blue screens was:

PFN_LIST_CORRUPT
STOP 0x0000004E

ATIKMDAG.sys
STOP 0x00000050

If anyone could help I would greatly appreciate it as it's getting really annoying.

Welcome aboard, Minicale.

It is crashed by the displau driver, apparently. Try updating it to the latest one,

   Information

WHQL
Release Date: October 22nd 2012
Version: 12.10
In Device Manager: 9.002

Latest AMD Catalyst Video Driver for Windows 7.

Also, check the temperature of the system and the graphics card itself using Speccy.

Clean inside the computer and the air vents very carefully.

Revert back from the overclocking.

Let us know the results.

Ok I have updated the amd driver to the newest one that just came out and found that I had 2 optional windows updates for 64bit systems that hadn't been installed and installed them and I use msi afterburner and speedfan to check the temps and I have never seen them go over 55C on the cpu and 65C on the gpu.

My PC is clean and I haven't overclocked so I'll see how it goes if I don't post back chances are its fixed.

That is a high temperature, and such a temperature, obviously more increased during gameplay, will definitely crash the system.

Afford some additional cooler.

What is the situation there, after updating the display driver?

My black ops 2 just froze and I looked at the reliability monitor and it said "Video Hardware Error" then "Black Ops 2 Stopped working" does this mean my graphics card is broken?

Stress test the Graphics Card using Furmark.

Depending on the result, we may decide it.
