black glitching lines on half of the screen

[Hoshimachi]

my hp gaming laptop started with 144hz refresh rate but then one day it started glitching and half of my screen did not work, note: i didnt do anything weird to mess up with drivers etc nor irl accidents, then i solved it by lowering down the refresh rate from 144hz to 60hz but now even when using 60hz my laptop started to do the same line glitching at the bottom part of my screen, i tried going up to 144hz but my screen goes fully black instead, i was saved by the auto revert.
