I get frequent crashes while playing games and upon visiting the game's sites I can find no solution to the problem. Is it possible that my Graphics card (9 Months old) is overheating? A few months ago I had a problem with my LCD monitor switching off and on when connected by DVI - I 'cured' this by connecting through the D Sub - could that have also been part of the problem? My card is a Powercolor Radeon 9600 Pro. Is there anyway that can I check if the fan is working without taking off the side of the computer?
