Screen Stuck on Backlight when Turned On

[Amadeo]

I was watching Twitch on my laptop like any other night, and all of a sudden nothing on the internet would load. I then shut down my laptop because I wanted it to reload everything so it could go fast again, but now instead, it's stuck on the backlight right when I turn it on. No menu, no startup screen, just the backlight, then it would turn off instantly with a short whistling noise if I were to click the power button again. I tried another recovery that i found for it by opening BIOS recovery, but it didn't display anything when I did it. All that did was erase the BIOS, and i know that because a screen appeared saying it was missing the BIOS. I would like help with this issue.
