So the game will crash and my monitor will just say monitor is going to sleep and I cant use the computer there after I have to manually restart it although the tower is still running. I had this issue before with War Craft3:Frozen Throne but that seemed to stop or at least be less frequent. So that being said I think the problem is my graphics card but Im not sure why It has the most recent drivers and here are my system specs. If any one knows what the problem could be much appreciated especially since I said above it has happened on another game. Thanks

I have fixed the problem for any one that has the same issues with the same grafix card appearantly this is a common problem with this card. I fixed it by cleaning the heat sink to out of box cleanliness and replacing the factory thermal paste now the card works better than new no crashes, now i will pat myself on my back and say thank you all.
