I had a Radeon 9200 video card which I used for some time. For
apparently no reason, it started showing vertical Magenta stripes that

I have a lot of parts sitting around so I tried a Radeon 9250 and
things improved. But still similar problems.

Look closely at the icons and the scroll bar. I have the similar
Magenta vertical stripes that flicker on when the screen redraws.
Also I have green vertical stripes in photographs and dark colors.
Any suggestions would be greatly appreciated. I am presuming that it
is hardware but it would be a coincidence if two graphics cards had
similar issues. I tried another mother board and it made no
significant difference.
I am using the radeon driver: xf86-video-ati-6.12.4 and Linux 3.0.4
with X.Org 1.7.1. All 32 bit.
Thank you for the assistance.
I tried the X1650 and it has problems too.
I am not facing a simple quandary. Either I have three defective video
cards or there is something wrong with the AGP socket on my
motherboard. I am going to explore the possibility that the AGP socket
is the problem.
