Its an MSI 8800GT OC edition(stock cooling) which never gave me a problem until yesterday.I usually play assassins creed and Battlefield 2, it goes on fine until suddenly the game locks up for about 1-2 mins and then comes back to normal. This happens every 10-15 mins of play. Thought of checking the temps in riva tuner 2.08, it was nice and cool at 59-60 C when not playing but, ingame it shoots to a terrible 80 C. I got the card back to factory settings, still the same thing. I increased the fan speed to a noisy 100 %, still nogo. My overall system performance is pretty sluggish too. I am using 7.15.11.7474 (174.74) version of drivers. What can be done to avoid this as i never had problems before with the card. Is it because of the drivers or is it because of the modding inside the case (CCFL's n stuff) thats making this card angry?
