Hi, for about a year now I've been having the same problem, which is mainly when I play games I get flickery textures and coloured dots appearing on the screen, then getting worse and ultimatley crashing my computer. Recently however, I have been getting various similar problems on my desktop aswell. Coloured dots appear sometimes when I move windows around the screen, and sometimes when I do this the monitor blacks out and shakes for a second (as if I had pressed the degauss button). Programs like media player with visualisations or effects tend to produce more artifacts. Also, occasionally, in my web browser, and other programmes with text (this includes menus in my games etc) the text gets distorted, however, if i highlight the text, the distortion goes away. The first artifacts that I notice in games are usually corrupt text graphics. Recently, the artifacts were getting so bad that I could barely use my computer. However, I decided to switch the ram into different slots and this seemed to eliminate the artifacts. After a while though, they returned. Here are my specs: inno3d Nvidia 6800 GT 256 mb AMD athlon xp 2600+ ASUS a7v8x-x mobo 768 mb ddr ram (2 sticks) audigy 2 zs sound card I should mention that my card is not overheating (neither is my processor), and that all the correct drivers are installed. I have also formatted several times but the problem persists.
