XPS M1710 NMI error discussion

Hi there, first post so bare with me please

For months now my laptop has been coming up with an NMI parity check / error in blue screen after about 5 minuates of playing games. I have looked through loads of posts about this specific problem and people seem to have different solutions, wich is probably because this error can be caused by different things.

Im almost 100% sure my problem is to do with heat in the laptop, more specificaly the graphics card, overheating. I recently contacted dell about this and i am now to recive a new graphics card (the 7950 gtx as apposed to the 7900 gtx). Anyway the reason i belive it to be heat related and not driver related is because i found a "temporery fix", in that my flate-mate has a large portable fan, the past few months i have been using this fan, pointing it at the back of the laptop and the nmi error blue screen rearly appears, however without this fan i can get this error within a minuate of playing.

Just wondering if anyone else has had this problem and had there graphics card modle changed, not just replaced, if so what was the outcome, thanks for reading

 

Update - Just got the new graphics card insrted and the gpu temp has kept at a steady 60c with game settings full. This morning my old one was sitting at 69c just browsing the internet! Anyone with the,
