Re: GPU Problem (I Think)
a new and card with a better cooler will do the trick, but it might be a little too much to
do only because of overheating.
so here is what you can do:
clean the fans in your system. make sure there is no dust blocking the air from entering or leaving the system.
if you have a overclock setting, reduce it.
add an extra fan to your system or replacing a bad fan with a better one.
if you are not playing any demanding games, then you could try to underclock it.
it might help for the game that you are playing, but you also lose gpu power so other and more demanding games will be less playable.
