Hi,

I'm running Windows XP SP2 with an NVidia Geforce2 MX 400 graphics card.

When I enter Windows, there is a grid of equally spaced purple dots on my screen. When I drag a Window across the screen, these dots somehow get "dragged" along with the window, making the window contain a flurry of purple lines. When I minimize and maximize the window again, the lines are gone. Also, when I scroll up and down, the dots get scrolled too resulting in vertical lines across my screen.

I tried printing the screen to mspaint, and the lines show up there too.

This problem has been around even before I reformatted my PC just awhile back. I've also tried downloading the latest drivers afrom the nvidia site after the reformat and installing them but to no avail. I know it is not a problem with the monitor or the cable because I have plugged this monitor into my laptop and it works fine. Also, I noticed that the dots are not there when the computer boots up and during the Windows loading screen. They only appear at the "welcome" screen.

Anyone have any ideas? Thanks.

Yup, in safe mode too. I've also tried reseating the graphics card and that doesn't work. I want to test using another card but unfortunately I can't get my hands on an AGP one right now....

Remove the graphics card, check the heatsink on the video chip to ensure that it is properly seated. you may need to remove the heatsink, clean all the thermal compound off the chip and heatsink, reapply thermal compound and replace the heatsink onto the card. "Warning" if you are not familiar with graphics card hardware dont do this yourself, you can ruin the card.
