I downloaded 911 FR from amazon a few days ago, and installation went fine. When I started to play my computer just shuts off after a while of playing (it could be a minute or two or it could be 20 min). I also installed the LA Mod, but the computer shuts off just the same with it installed or not. To describe the "crash" a little better: I will be playing a mission and all of a sudden the computer shuts off, no freeze or anything, it just plain turns off, like someone removed the battery. I have updated the BIOS, graphics card, directx, audio drivers, etc, anything I could think of before posting on here. I realize I have a dynlight error, but I have updated the graphics card and checked and rechecked that I installed correctly/downloaded the most current drivers. It doesnt seem to be an overheating issue because I have cleaned the dust out and I can play much more taxing games without the computer having any problems (civilization 5, sims 3, tropico 4, etc). It makes me think there's some issue with the software with the game I downloaded (from amazon), I have redownloaded and reinstalled, but nothing helps. I can't think of anything else to do, I have posted the log file and dxdiag. Any help would be greatly Appreciated.
