Acer 6920G Switching off after around 15mins of gameplay...

Hi i havent played games on my laptop in a while and recently decided to start playing games again after upgrading to Windows 7.
I installed the drivers 197.16 for my Nvidia 9500m Gs and started playing Age of Conan. My laptop seems to be heating up alot and the fan is always on when playing. I have read up alot and have fixed the throttling problem by using Throttlestop. Also i have disabled powermizer through resistry settings. The main problem i have now is after about 15 minutes my laptop just switches off for no reason. I have checked my temps using hw monitor and GPU gets to around 80 degrees which could be the problem? Any help on why this is happening would be greatly appreciated

 

Clean out dust
Check with some other games (PC game crashes not entirely unknown )
Run Memtest86+ boot disk to check for memory problems

GPU at 80c is not normally a problem . . but lots of systems have developed solder joint problems onthe GPU caused by repeated heating and cooling of the tiny solder joints

 

Hey thanks for the tips i have tried opening it up and that seemed to help a little bit with temps.
What has seemed to have stopped the shutdowns is underclocking my cpu so the temps are lower my gps still gets to around 80 degrees and my cpu 79 degrees ut my laptop no longer shutsdown during gaming

 

Guess thats the answer then

Enjoy
