Hello, I have a desktop compaq/vista. Recently, my computer has been restarting on its own. Until one day when I went to log in my keyboard and mouse won't work. I don't have a backup disk, it won't let me do a system restore and when I tried to do a recovery the dvd drive is not reconizing none of my disk. My mouse and keyboard works perfectly in bios. I truly need the documents, music and pictures saved on my pc. What can I do?
