I need some help. When I turn on my computer, everything starts as usual, until it gets to loading my desktop. The background wallpaper will appear, but that is it. No icons, no panels, nothing. When I press ctrl+alt+del the window will appear, but from there, the computer will not allow me to do anything. I have also tried manually shutting down the computer and simply unplugging it. Nothing has worked. PLEASE HELP!!!
