I found my desktop icons scrambled -- and I had lost the shortcut to the Dell-All-in-One Center which enables me to select among Copy/Fax/Scan and to adjust the various settings. I am running Windows XP, Svc. Pack #3.
I could still print from both the computer and the printer's control panel . Copy also worked, but Scan and Fax did not work even from the printer's control panel. I could not get to the Dell-All-in-One Center no matter what I tried; that included following troubleshooting instructions. The printer's USB connection was functioning properly, but the printer was not listed under "All Programs." However, It could be found through the Control Panel --> Printers & Faxes.
I've run System Mechanic, Malwarebytes, Ad-Aware, and AVG without solving the problem.
I uninstalled; then reinstalled the printer from the original CD. The software loaded, but didn't get passed "Searching for Printer."
I tried several Restore Points, but got the "Couldn't restore" message each time.
There don't appear to be any other issues with the computer. SUGGESTIONS?
