Sufficent video card heats up and causes game to crash. Help!

First of all, some system specs

Windows 7 64-bit OS
4 GB ddr2
AMD Phenom II X4 B40 Processor (4 CPUS), 3.0 GHz
Nvidia GeForce GTX 470

In the past I played the game, didn't like it, and unsubscribed--game ran great, though.
After hearing about the major changes in the game, I decided to give it another go. Upon beginning playing, the fan on my video card--I'm pretty sure it's my video card--starts to spin faster than I have ever heard it spin. It keeps getting faster until, without warning, my computer shuts down completely, which I assume is the system trying to protect itself. Now, while this could very well have something to do with overheating or poor ventilation, part of me doubts it. After all, I do run gpu-intensive games such as Witcher 2, Starcraft 2, Dungeon Siege III, and others without a hitch, Final Fantasy XIV seems to be the exception.

I tried playing a few games after this problem in order to check if my card was dying, but there weren't any problems--in fact, my video card remained completely quiet.

Help!

Appears I fixed my own problem. I had everything on the highest because I was sure my video card could handle everything at the highest, which it can, but it overheats. Lowered my settings and seems to work just fine now.

You can also just set the fps-limit ingame to 30. That is what the PS3 will run the game at too <.<

Glad you got it sorted out.
