Vaio no box for me to put my password in

Hello, Last night I was looking on my laptop, then all of a sudden the Sony Care guide popped up, nothing unusual, told me to scan, so I did, then that's when it seemed to freeze up, then it shut it selfdown, that's find. The problem is that when it starts back up, there is no box for me to put my password in. It's never done this. Please can any one Help? I did do the assist button when off, the rescue mode comes up, then it's asking me to pick what files and folders I want to keep, cause a lot of them came on the laptop. Help????????
