Thats what I mean by weak. I'm not picking on you, what you have is what you have. To make it work you will need to turn down the "eye candy" in the game, as well as getting your computer to run as clean and lean as you can. You barely have enough processes speed, not enough ram, and video that is trying to us virtual memory to get by. The less things you try to stuff through it the better it will run.
