whenever i'm playing a game, it starts out fine, but after a while, the computer draws random lines and meshes from points to the center of the screen every frame. the game never crashes, but the graphics is so bad that i can't see anything that's going on in the game.
my guess is that it's something that's wrong with the directX in my computer.
it might be because i installed the directx sdk. hopefully it's fixable.
i tried reinstalling directx 9.0c but it still does the same thing.
