Do you have IE7 - if not install that and if you still have problems see the link below. Strangely some people have fixed this problem by installing IE7. The Blue Screens of Death could be caused by a number of things. A lot of people have problems with this game crashing especially when trying to use DirectX 10. Anyways if none of these fix ur problem then try the new processor and
ram. However I've read a that a few ppl have tried that and it made no difference.
