Windows 10: 1 Wide black pixel line under my taskbar Windows 11

Can someone help me to get rid of this glitch black line under my taskbar?The black line under my taskbar looks like a glitchy pixel. When I hover my cursor at the top of my screen, It will also show under the black line in the taskbar.I did already a lot about this but still I am not able to get rid of this. PLEASE HELP ME I WANT TO GET RID OF THIS PLEAAAAAAAAASE!!! T.T

Dotted 1 pixel wide line vertically on screen.

I'm asking here as i am pretty sure this is a software problem as when i move my mouse over it the pixels change colour and therefore are not dead. The pixels themselves are dotted blue and black 1 pixel wide vertically in a line down my screen. I first
noticed it a month or so ago but it went away after a few hours. Since the it has kept randomly appearing and disappearing when i use my computer. It may be useful to note that it seems to be in the location where i usually have the border of one of my windows.
(i usually have 2 windows open at once and the border between those two windows seems to be where the line is drawn) this may be especially interesting as recently i moved the window border slightly and the next time the line showed up it appeared in that
new place. This could all be a red herring however. I would very much like to hear from someone who may be able to help as it is very unusual and distracting.

Other potentially important things to note:

I use 2 monitors

I use a nvidia 1050 Ti graphics card

The monitors i use are Samsung C24F390 24 inch curved screen monitors.

Any help would be greatly appreciated.

 

Black Vertical Line just on my desktop screen

Hi,

I have the similar problem in my lenovo g50-80 with windows 10. it's like this -Whenever I open a window on the desktop a 1 pixel wide vertical black line appears. However
when I press win+D or click the right side of the taskbar to show the desktop the line disappears. But if there is a window open on the desktop or I manually minimize/close all of my windows the line remains.

I've tried the the support engineers suggestion but it didn't work

 

Line of pixels on startup preventing windows to boot

Yes I've tried both suggested steps. Unfortunatly the problem is still there. It doesn't happen as often as before, more like 50/50. But when the pixel line is there, my pc does not boot up anymore. First when I waited for a while, it did boot up. But
now it's just a black screen and nothing happens.
