I've read quite a few questions on SuperUser of people having laptop shutdown problems but mine is different.

My laptop specs:

  • Intel Core i7 3610QM (IvyBridge)
  • NVIDIA GT630M 2GB and Intel GMA4000
  • 8GB RAM
  • Windows 7 64 Bit

My laptop occasionally shuts down when playing FarCry 3. It's around 5 months old. I've played games like Crysis and it never shuts down unexpectedly. Since I experienced this shut down recently, I decided for GPU-Z to log the temperatures. The final log value at the time of shutdown were thus:

GPU Core Clock [MHz] - 797.3
GPU Memory Clock [MHz] - 896.8
GPU Temperature [°C] - 89.0
GPU Load [%] - 99
Memory Controller Load [%] - 36
Video Engine Load [%] - 0
Memory Usage (Dedicated) [MB] - 535
Memory Usage (Dynamic) [MB] - 53
VDDC [V] - 1.0620

My drivers are up-to-date and I didn't encounter any BSODs at the time of shut down. It simply turns off.

Does the machine feel hot at all or does the fan sound extra loud? Typically, a shut down like this is due to heat. Does event viewer give any indication as to why? Try and download the program WhoCrashed and see if that can shed any light. –  Dave Rook Dec 17 '12 at 11:02
