I have a Gateway laptop model number 400VTX. Goodness, I must have gotten it early 2000's some time while I was in college. It worked fine up until last year. I was watching a movie on it that I was streaming from the internet. In the middle of the movie the screen went black. I have tried restarting it. When it starts it sounds like it is searching the cd drive for a disk. The lights on the bottom half/keyboard come on. The screen stays black. I am not sure if I need to take it in or if I can fix it myself. Any help you can offer? Thanks.
