My laptop would now power on and keeps making a buzzing sound after every small interval

Hello, I am not able to open my laptop. I was working and then suddenly the screen froze and pixelated. When I powered it off and then back on, it wouldn’t turn on. The screen would slightly flicker as it does when it is about to boot and then I hear a buzzing sound. And then the screen switches off and then it flickers again followed by a buzzing sound and so on. I tried discharging the battery and tried using the laptop without the battery by just connecting it to the AC power adapter but the problem stayed.

We can proceed when you provide the information.
