Hi there, I'm new to the site and have been having a problem with my Presario 2500 laptop (Compaq). When I turn it on it starts up normal and all, I get the windows logo with the loading bar beneath it. As soon as it goes to switch screens to my main screen w/my wallpaper, shortcut, etc. I get no display at all, but still get the welcome music. I don't get it. Any ideas?
