Texture malfunction? I'm unsure as to how to explain the problem I'm having. A few days ago, when my friends were playng a game (Heroes of Might and Magic V), the screen began to produce odd colors. The way I've been explaining it is saying that the textures weren't meshing properly. At first, after the game was quit out of and the computer restarted, there were vertical lines going through the screen in a pattern, varying from black to rainbow colors. I unloaded the game, performed a system restore, cleaned my computer by dusting the inside of it carefully, and deleted and reinstalled the driver off of the Dell website. Nothing actually fixed the problems for very long.
