A little update, i've ran EVGA precision on my graphic card( GTS 250) temp, and sometimes it goes up to 80 + in games. I've tried a Furmark stress test, and it went up to 95 in a short lapse of time, i would say 5-10 mins. ATI tool didnt go that high, i stopped it at 75+. I'm trying to find why my computer restarts randomly during gaming. Thanks for you help!
