hi all. i own a gygabyte 9700 pro, and suddenly i got heavy image problems, most of the time they appear when i'm playing, but now (a few times) i just have to wait a few minutes after turning the pc to see the problems. i have no cooling system, only the fan that came with the card. could the card be overheating? the drivers i'm using are the latest from ATI(5.3), but i was having problems with 5.1, i think i don't do any kind of OC, so i really don't know what causing this. if anyone had similar problems, please let me know what to do. thanks.
