Monitor had black pixels that fall horizontally every time i boot up (PC only)

as the title says, every time i boot up my PC, my monitor screen is this tall black wall of pixels, that over time drops down horizontally. It glitches up and down in a small distance but gradually falls and the screen is normal. This black part of the screen usually mirrors something from the top of the screen, like in my lock screen it has a long white bar in the middle for the clock that's at the center top. as shown: https://imgur.com/gallery/monitor-pc-issue-fTEsBbZ

This has been a persistent issue for a few years, but it wasn't something worth bothering myself with because it would take max 10-15 minutes to go down fully, i reached my breaking point because yesterday it took 2 whole hours for some odd reason.

The issue only shows on my computer and laptop, before getting my PC and connecting the monitor via DP, i thought it was a problem with the HDMI ports either through the monitor or laptop, but the issue still persisted. The issue is completely absent on my Playstation.

I want to know possible fixes or eliminations of this issue, as i dont know what to search for to fix.
