Hi, I am having some problems running some games on my computer. I have a AMD64 3200 512MB Ram and a GeForce FX5200 card. The problem is that when I play some games ( Rome:Total War, DeltaForce Blackhawk Down, Battlecruiser3000 , Starwars Battlefront, Battlefront Veitnam) the games would freeze for about 2-10 seconds every minute or so or the screen will go all patchy with great swaths of color striped across the screen. I ave down loaded the latest drivers. Reformatted my hard drive and reinstalled everything . Any ideas ?
