what kinda game are you trying to play? and it could be, i have a radeon 9200 in my comp too, if it's a newer game, then there's a good chance that your overloading your video card, becasue the game's graphics/other shit are too complex for the card to handle.

9200 is quite a few years old, even if it isn't the video card, still not a bad idea to upgrade the card... if you got the money to afford to do so, i'd suggest just go ahead and upgrading, and seeing if that helps.. if not...
