Hi guys, i have discovered a problem with my father in laws video card. i think that it is overheating and either crashing or going into a fail safe. he likes to play an older game (soldier of fortune 2) so he isnt ever really stressing it, but i have tried to play more intense games lately that truthfully arent even that taxing, i mean they are no crysis. i have tried mass effect, me2, never winter nights 1 and 2, oblivion, lord of the rings online, and a bunch of other games. every game i play everything will run fine and then after a few mins of playing the screen goes black, as if the monitory looses signal, (well it is loosing signal it says so on the monitor) but i can still hear some sound in the background. the only way to get out of this is to hard reboot the system. so i think his old gt220 is getting over heated with newer games, if you guys agree and think this could be the issue could someone explain to me how to underclock it? i have tried evga precicion x but i dont think it worked as the games still crash. and i have updated the drivers also. any help would be greatly appreciated, i have a+ certification and can learn most of anything i need to do by reading most peoples forum questions like tutorials but i cant find any that work for me. thanks yall.
