Im having a display problem with my computer

[BoNgBlAzE]

Hey, I built my own computer about a year ago, here are the specs
Asus A7V333 MB
AMD XP 2200
WD 120gb
Samsung 174v LCD monitor
Nvida GeForce4 TI4400


Just recently , I have been having problems with the display. There is little pixels on my screen, not in the same place and they change colors and positions.
Here is a picture of the problem.

Thanks for your help

Are you overclocking.
They look like artifacts from overclocking the vidio card to far.

Either that or your vid card memory is on the way out.
If so how hot is it in your case.

Luck.........

yeah, those looks like artifacts... check wether the fan on your vid card is spinning...

Im not overclocking at all.

I checked the fan and its running.

I hope I wont have to replace anything.
