I have a laptop 5150 that has a pentium 4, 6oG of space, 768 of ram. And when I play games like Rome Total war, Tiger woods, and MVP baseball 2004 it runs fine for awhile than game play becomes jerky meaning that hitting a baseball is quite difficult to hit when the ball slows down than goes fast again. Is there anything I can do to fix this problem? I did everything I thought that would help. I ran spyware, defraged, and virus scanned and nothing worked.
