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.
