Ok I finished building my wife her new computer and everything is running fine. The computer plays Crysis on Extreme settings without any lag or shutdowns. When she plays The Sims 2 for about an hour the game freezes then shuts down. After several days of scanning the web for others with this problem only thing I could find was to update a driver. Well aparantely it is not working; the game will still shutdown. If anyone has any idea on what could be causing this please let me know. And yes all drivers; ati graphics card, bios, and direct x , all up to date. Hopefully someone can help me out on this issue.
