Afternoon to you all. I've got an annoying glitch which i can't get rid of. I'm running Vista home premium on an Acer laptop, with an ATI Radeon HD 3470 graphics card, but the computer says that i'm using the wrong driver, and i'm getting a white screen flicker which completely covers the screen, and seems to have a horizontal orientation. Can anyone recommend a solution? I'm seriously thinking about throwing this damn laptop!
