I am using the most up to date drivers for the 8800 gt from the nvidia website. I installed the software that you linked and put he fans to 100% and I am still checking to see if that fixed it. But one problem that has happened is the screen will freeze in game and then the monitor will turn off and then back on and the game will go back to normal. When this happens sometimes the game will crash and I will get the message that my drivers have stopped working. So far it has done this once since I have put the fans to 100% and it did not crash when it happened.
