I'm going through the same thing...This is what happened to me. When I turned it on some message came on after I put in my password, something about programs, then my screen came up with all my icons. My background pic that I had was gone, it was now Gateway, (like it reset itself), so I went into my pictures to reset it and all my Pictures, documents, etc.. are gone, even when I click on my HP Photo icon, all my pictures are gone, all my itunes songs, everything from my icons is like its brand new, nothing is on it. I have no idea how to retrieve them. I did a full virus scan, and there is no viruses, etc on it, so I don't know whats going on? Another thing that I noticed is everytime I turn my laptop off, and turn it back on, everything I did as far as changing my homepage is gone as well, even all the sites I just visited,like it keeps resetting. I hope someone can tell us whats going on......
