I've had this problem since first startup a couple years ago and Dell refused to give me a new videocard and then my warranty expired. It only happens when I play a game that runs OpenGL or DirectX. I get very uniform artifacts in either 3 or 4 sections running down my screen. I have updated drivers, I've reinstalled the drivers. I've also been looking around at corruption problems online for a while and have never seen one that looks like mine. Can anybody help? and you can see it real good in this Flightsim pic.
