something weird happened on my computer about a half an hour ago and now all of my icons on my desktop have disappeared, as well as the task bar at the bottom. The picture I have set as my background is still there but everything else is gone. I can access different applications by pressing CTRL-ALT-DEL and everything seems to be running smoothly but everything is still gone on my desktop. It won't even let me right click on it...can anyone tell me what is going? Any advice would be much appreciated!
