Windows XP/2000 - unspecified error posted in the Operating Systems forums; about almost every five maybe ten seconds i get a message saying unspecified error, i have included a picture...
Let's see if we can get to the bottom of this for you. Doing the following will help us diagnose the issue you are having...although from the look of the desktop, I feel the wallpaper, broken image at the top and the fact that the background of the icons are not transparent may have some bearing.
Right click on My Computer and select manage > event viewer > applications. Do you see any problems in there? If you do, please give us as much detail as possible...also check system in that location.
