I have a Dell DIM3000, Model DMZ...just recently I keep getting this message each time I boot my computer:

"Windows Installer Scan." Then a window comes up telling me to insert disk. There is no disk for this, and then I get - "No valid source could be found for product scan. Error 1706."

By pressing Alt/Ctrl/Del, I can take care of it and everything works okay.

What is my problem and how do I fix it? Thank you for your help.
