HP Pavilion Won’t Start

[pavilion_girl]

Hey community, I’ve owned an HP Pavilion laptop for around a year now and I’ve had no issues with it until today. My laptop is having issues with starting up. For example, I press the startup button and the light turns on but the screen doesn’t. The light proceeds to flash a little then turn off. I’ve tried tons of methods already but none seem to do anything. I hear no noises coming from my computer whatsoever. What else should I do?/What could be the problem to this?

Here's a video from HP Support about diagnosing the issue of the laptop starting but having a black screen instead of any display:
