Game causing PC to crash

[ntall1]

Well.. the game will not shut your PC down. Your PC will only auto shut off to protect it self in very specific situations. Those are overheating, power surges, or power loss. Lots of times PSU's are the issue. Either there is not enough power going to your vid card. (This would normally cause your GPU driver to crash and not shut the computer off.) Or something is overheating, and your computer is turning off to protect itself.

Just because a PSU says it can handle something doesn't mean it always can. Most PSU's run on a single 12v rail. Having lots of stuff on this rail in addition to a high end vid card can cause the exact issues you are having. You can have a 10000000w psu and still overload a single 12v rail pretty easily. This is why I recommend underclocking the GPU. If its a power issue an underclocked GPU will draw less power, and if it is an overheating issue, and underclocked GPU will generate less heat.

This is why I recommend looking at the Even Viewer to see if it logged something. This can help you pin point what is causing the problem. If an event fired before the shut down saying your GPU driver has crashed and failed to recover. You can assume it was due to overheating, lack of power, or even too much power. If it was your CPU overheating there will be an event for that saying your computer has turned off to prevent dmg.

The Nvidia GTX 660 takes a 140w by itself, and requires a 6 pin plug in from the PSU. This is not because it requires almost none of a PSU's power.
