It was stuck loading something when I was trying to get work done, so I decided to restart it. Then it got stuck at the "Restarting..." screen, so I decided to press the emergency restart or cut the power, don't remember which one. Now when starting up, it shows the first screen, which is about the hardware itself...model and so on. But then the screen goes black and the windows logo won't show up. It used to go black for a sec before and then show a blue windows logo loading for a few seconds and then go to password screen. Now it just stays black forever after the first screen.
