Strange blocky graphics and reddish stripes!

[nickname89]

Everytime i boot windows xp, there are reddish blocks or stripes on my desktop. They are overlaying all applications, games, etc. Their appearence changes from blocks to stripes if I change the resolution.
Comparable graphic errors also appear on the startup screen and on the asus-logo screen that shows before the boot process starts.
I did not install new hard- or software.
I tried to update the graphic-drivers and to reinstall an old one, but it didn´t change a thing.

Athlon XP 2200
Ati Radeon 9700 Pro
512 333 DDR Samsung Ram
ASUS A7V8x

Do you have access to another monitor that you can try?
How is your monitor if you have that powered on but the rest of the machine switched off?

1. What does the monitor do on another PC that is working ok?

2. What about another video card?

It´s not the monitor.
I tried 2 different models.
But I´ll have a try with the video card.
Thanks, so far!

It´s the video card. I installed an old diamond card and it worked normal. But with the Radeon installed I still get the graphic errors.
Is it possible that it´s not a harware problem with the video card? Maybe a bios problem or anything?
