Definately a hardware issue mate. With those specs now, you shouldn't have any problems running the game!
If you keep getting the blue screen error PM me. I can get you free driver updates. However, I will offer you a good program to use for your computer Tune Up Utilities. You can get a free trial and it will help clean up free space on your computer, and overall help it run a lot faster.
