ok, iv been through about 4 pages of this, and cant find anything to help... i have a dell dimension E5 and i have a radeon E330/E550 running windows xp media center edition. I have also just reformatted the harddrive, and needed to instill sound and internal wireless drivers too. I have been to the AMD website, and downloaded both the full graphics driver, and just a display driver, and neither have worked. I've checked the hardware acceleration and everything, and nothing seems to be helping... are there any other ideas as to what the problem could be and possible solutions?
