Im using Asus 8800GT TOP. I have a problem only when i play high end 3d games (Crysis and COD4), but its fine when i play normal games such as WC3.

When playing Crysis (especially), the game would crash with into black screen and then nothing happens next. The last time i thought it was the GC's problem because it reached 90C. But i installed a new fan which dropped the temp a lot. But, the game still hangs after playing awhile. Could it be the software prob or hardware prob?

I have the option to change it to other GC or just remaining the same.

TQ
