Hello KKKK, and welcome to Vista Forums.
Try right clicking on your desktop and click on View and then Show Desktop Icons (to check it) to see if that helps you.
Hope this helps,
I know this thread is old, but I cant believe it. I have been trying to figure this problem out for 2 days. Running different virus scanners and other various "fix it" programs. I have been reading multiple forums and never found anything that worked. THIS DID!
I just wanted to THANK YOU SO VERY MUCH! Saved me from a format.
