My laptop really started lagging and my decided to turn it off for some time but when I tried to turn it on it just said it was preparing automatic repair after a few seconds the screen turns black with nothing on it and all I can do is move my mouse. Please help I have no idea what to do. I've pressed every key on my keyboard and nothing shows up on my screen.
