A black vertical line on my screen

[Carolina_bm]

Hi, so, I have this problem with my screen and until yesterday everything was okay, but today, suddenly appear this vertical line on my screen. I thought it was a problem with my OS but after saw, it persist even when the OS was starting, I don't know what could it be. And If it's a problem with the computer screen, how this can happen? As HP all-in-one I don't know how to fix it, and the computer screen has never been harmed.
