I think this is little bit weird. I have just notice my icons on my computer keeps fading away and sometimes come back. I have attsched a screenshot (word2000) where you be able to see the icons in dots. This dots also appear around the pointer of the cursor when i move the cursor around the screen.
I more concern when i boot up my PC as i notice this around the XP logo at start up. It feels like my graphics card is on its way out, hopefully not.
