I'v got an AMD ATHLON 1800, 1024 DDR Kingston RAM, Geforce fx5200 with 128mb and a sound blaster live 24bit running on a K7S5A mother board with 300W PSU. The problem is that games freeze after about 2 mins if i run the cpu at 1533 mhz. I've only had the problem since reinstalling windows XP home. When i drop the speed to the minimum 1150mhz all is fine. CPU temp is 58 degrees C when it freezes but that shouldn't be a problem should it? Any ideas what i can do? Is it possible to remove Windows Service pack 2? I didn't have it before all the problems started. Thanks for any help anyone can give.
