i hv this GC 3 month ago and use it at very good condition. but i dono why this few day my GC have artifact when play game and i will have some artifact when at windows screen but not really very clear. i din OC 2 month ago already. The first time i have this problem is after i play "freedom fighter" about an hour then the artifact occur.

now i use Windows XP only not installed any service pack, is there cause the instability problem? i use ATI 4.10 driver.

Please give me some guide to solve this problem. thank alots.

anyone?? please give some guide to solve this problem.

ive some times gotten artifacts from windows itsself (not video card) try reinstalling windows and try a newer driver

download atitool and do scan for artifacts

If this happens after an hour of gaming then the card is overheating. Check/replace the TIM, or get a better cooling solution. Good case airflow is also important. A good card cooler can't work properly if it is starved for cool air inside the case.
