Bottom of screen goes black and flickering whenever I switch to 144hz

[Ghost23]

I own a Hp Pavillion Gaming laptop 144hz version. I have been using it for 1 year and a month but recently (it's been a week now) when I turned my laptop on bottom part of the screen around 3 or 4 inches was black and flickering then I think maybe it's a software issue so tried updating my drivers and even tried to go back on pervious version but it didn't worked after few hours i gone to settings and turn the refresh rate to 60 and it worked but whenever i tried to go back to 144 it happens again and again.

I even tried to go to bios in 144 hertz and it works fine in bios now I don't know if it's a software problem or hardware.

That black border goes away in 60 hz.
