I have a strange problem with my gf2 mx 400. Whenever I play a 3d game, after a certain amount of time playing the game, it locks up with a high pitched sound coming out of the speakers. UT, Deus Ex, and Half-Life have all done this exact same thing to me. It doesn't matter if i use direct3d or opengl. I'm thinking this might be a temperature problem because i don't have any case fans and all the card chipset has on it is a lousy heatsink. However, a strange thing is that it takes about the same amount of time for the lock-up to occur when i'm playing HL in 640x480x16 as when I'm playing UT in 1280x1024x32. I have the 12.41 detonator 3 drivers. Please respond with any and all suggestions. Thanks
