I followed the instructions and successfully uninstalled the old drivers, and removed the ATI entries from my registry. I noticed the lines after reboot, but they were not as bad and they were lower on the screen, near the bottom. I then installed the new drivers, and the problem is back.

The lines are back in the same spot they were in before.

What are your thoughts?

I just tried safe mode again, and the lines are there now as well, but just in a different position.

I guess it's the video card? It's a shame if it is, it's less than a year old.

Did you install or do you have XP SP2 as well as the .NET Framework?

Also: do you have another monitor to try?

Also: does your current monitor have a DeGauss button?

I do have SP2 & microsoft netframe work v 1.1 as well as a hoftix.

I don't have another monitor.

And I just tried degauss and it didn't fix the problem.

I'm really hoping it's the monitor, but I'm thinking it's the card, because the lines only start appearing after I reach the blue "Welcome" screen. What do you think? Got any other tricks up your sleeve?

Do you have your old card to try again?

What is the exact ATI model? There are some retro drivers here:

Radeon® 8500 series
Radeon® 7500 series

ATI All-in-Wonder® variants based on the above are also not supported.

Also did this card ever work OK?

The exact model is ATI Radeon x800xl 256 mb PCI-E. The card has worked fine since January.

Your question reminds me, I do have an old Nvidia 128mb PCI card. I will hook it up and give it a try.

Will update.

Either the new drivers are faulty or your video card is slightly damanged (in a way that only newer drivers make use of ). Keep the old drivers for now at least till the a newer set are available to try.

This would be your CRT as the printscreen wouldn't show it.
