Computer is home grown Pentium 4, 1.8 using a Gigabyte GA-81DX board. We tried a different video board and all was well. But with the ATI all in wonder - it keeps us up nights wondering why we bought it. It locks up and changes text to an unreadable mess. We have installed the new drivers the best we know how (all the notes ATI sticks in odd places on topics such as the order of load and when to restart or not makes us only guess we did it right). The Sept 12 drivers helped some. Then with adjusting video performance (so many controls) we got it to work "slowly" for most things except when on the internet. When it goes down it blames ATI video card. I am not a computer expert, especially with Xp, please go easy on the terms. Thanks for any ideas. Bob
