It's sounds like Nautilus is no longer drawing your desktop. Did you change any settings in the configuration editor?
Regardless, go to your applications menu. Under System Tools -> Configuration editor.
Use the left tree view to navigate to: apps -> nautilus ->preferences and make sure that the 'show_desktop' option IS CHECKED.
If it isn't, then check it and exit the Configuration Editor.
open a terminal and enter the command

nautilus

leave the terminal open.

Under System -> Preferences -> Sessions, select the Current Session tab, select nautilus and set the Order to 40, and set the Style to Restart. Hit Apply and then switch to the terminal window.
Close the terminal. Nautilus should exit and a new instance should start.
Close the Sessions window and log out, making sure to check the option to 'Save current setup'.
Log back in and you should have a fully functional desktop again.
