Well, I booted up my computer again, and everything is running smoothly with the screen working and such. I do my usual activities like going online or play some video, but after a couple of minutes the screen just shuts off. Even when I move my mouse the screen doesn't come back on.
So I rebooted the computer again, but as it was booting the screen shuts off much earlier than before. Even when I tried to get to Safe Mode, the screen still shuts off.
