BSOD Not sure if its cpu related

[blitzyuk]

Hi all
I was playing Call of duty:Black Ops Multiplayer earlier and got this BSOD that i have never had before:

Does anyone have any idea why i got this or is this even a CPU problem or a GPU as im unsure.

My system info is in sig.

Well this is the thing its an Ocuk overclocked system and after the initial overclock not being stable rjkoneill helped me out to get it running stable. So not sure what to do now.
