My computer worked fine. I could play all games. I didn't changed any hardware or software it just happend. 3 days ago I was playing nba live 07. Suddenly it occured that the screen froze. It was like that for about 10 seconds. And than it continued. It happed several times, and finally PC shutdown itself but I could still hear cpu working. It's just there was black screen on my monitor. And now when I play intensive 3D games it shutdown the 1st time it froze. PLease tell me what to do. I installed SpeedFan, it tells me ambient 33*C, remote1 55*C remote2 35*C HD040*C Core 27*C. I don't know what remote1 is. But when crash occurs remote1 temperature is about 72*C. I tried to open the cover. I Put BIG fan to blow into computer.All the temperatures are low but nowthing really happend. My remote1 temp is now 52*C but still pumps up to 70*C when I'm playing games. And the crash occurs again.
