lately ive been having real bad problems with my graphics card over heating. normally it would sit at 50c normal and while playing it would go up to around 78 not to bad. but as of a souple of weeks ago it when it just sits there the temp goes up to around 77 and while i play any game be it bf 2 or c&c red alert it will jump to around 110+. i always clean the shit out of my comp and the card. its a bfg 6800gt. any help would be greatly appreciated.
