my system gave me a blue screen (not bsod) last might while playing my favorite multiplayer game. i was o/c'ing my card so i thought it was a heat issue. i set the clock speeds back to default and rebooted. all seems fine but when i play that same game, i get freeze ups quite often. some are only for a second or two and others actually freeze the system. do you think my card is going bad? how can i test it? i ran 3dmard03 and all seems fine but something tells me all is not well.
