I would turn on my laptop and it would show the sign in screen, and when I would try signing in nothing happens. I've turned it off by holding the off button for at least 30 secoulnds then I would turn it back on and it's the same thing as before. It's as if all the buttons don't work, except the on button. Then if I get to type in the password, it would load for a little bit then the screen would turn black and I can only see the mouse.
