My Nvidia Geforce 6200 Agp card got hot from dogs hair in the fan and when i was playing (Didnt know about hair) the game froze, so i restarted and played again for a couple of minutes and boom froze again. I touched the graphics card and it was very hot.So i switched the pc off immediatly and removed the card and cleaned the fan i put it back in but now the monitor flickers on and off constantly and when it stops i try opening a game and it runs for like 3 seconds then restarts the pc. I tried reinstalling the pc and downloading drivers for the card but still doing same thing. I took it to an electronics expert to ask him if its damaged by the overheating and he said no because the board would have changed a different colour(Back of processor chip) .Please if anyone can help i would really appreciate it . Thanx a mill
