Hello cf, I recently picked up a new video card to replace my old radeon 2600 the new one is a radeon HD 4670 after I throw it in my tower I tried installing the drivers off the disk that came with the card, after I restarted my computer the computer would load up just fine but after about 2mins the color would go all retarted. The screen would go black with two parralell lines of green doing down it and then come back up but the screen would be all pixilated with pinkish red. I uninstalled the drivers and it worked fine. Th refresh rate was sluggish as hell but it worked. So I figured maybe the driver was outdated and went to amd's website to find the newest one.I tried installing that one and had the same problem. I tried every driver for the card I could find and none want to work. I have never seen this probl before and have no idea how to fix it. Right now I am running xp media center edition. Any help you guys can provide would be apreciated thanks
