Normally i always seem to find the answer to all of my problems.This time i need some help if you don't mind.I've searched many places but couldn't seem to find the right information to help me out. As you may know by the Title i have a "Geforce 6800 GS" plugged into a Asus K8V-MX ,2 GB ram, Athlon 64 3200+,Updated Graphics drivers,550 Watt PSU. When i run Halo it'll freeze up either 2 seconds or 10 minutes and sometimes i get a Blue Screen,but sometimes the PC restarts instantly.And Few of the times it will say Hardware Acceleration is disabled once my game freezes it'll say that for halo.Hardware Acceleration wasn't even disabled.I restarted and my games worked again till the next crash. I reformatted and updated graphics drivers. But Before i upgraded my System GA-7VT600-RZ ,Athlon XP 2800+,Ram Video card and PSU the same. No crashes,even with my CPU Temp at Idle 72C.touch it and get burnt. Better Yet,Higher FPS in all of my games! But the video cards TEMP is 68C idle i'm not sure what it was in the Gigabyte board. I really can't remember what the blue screen said but i'll try to see if i can get it to show up again. Thanks in Advance!
