I have Vista on a Gateway laptop, and just today when I came home from a day of fun. When I boot up my laptop all goes well until I get to my desktop and everything, its just a black background, and my documents pop up. but I cant turn down the volume, and I can do everything on my computer its just that the desktop wont show, I can watch dvds, plays games and everything. I havent really tried that much to fix this. Any Ideas?
