about 5 minutes ago my laptop suddenly shut down. When it rebooted to led me to a screen where it listed my main profile name, and asked for a password. I dont use one, so I jsut clicked enter, and it started to log in. Then suddenly a window popped up where it said windows Data Execution Prevention has closed "Userinit Logon Application". Once I close the message my computer just shows my mouse and background. Is there anyway to save my hardrive? I have tons of music and videos and work that would take forever to get back/replace.
