Laptop keeps going black and restarting

[u/No_Pudding6313]

I got my laptop fixed, had its keyboard + motherboard replaced, but when I have a ton of tabs or even a game open while simultaneously charging it, it’ll go black, a weird and soft buzzing noise will play on my AirPods, and it’ll just reset itself. It never used to do this no matter what I did before I got those parts replaced. Any idea on what I should do?

The laptop is an HP Pavilion Plus
