Windows 10: Black bar covering bottom of screen/taskbar.

My screen has been like this for a while, but i didn't think much of it since it started out small and it didn't bother me because it was only blocking a very small portion of the bottom of the screen, I was able to click the start button and search and use my taskbar fine until the black bar kept getting bigger. Now I can barely find anything on my taskbar and my cursor gets stopped by it as well, making it hard for me to even click on anything. It also doesn't go away when i put on a game or anything, it's stuck like that. I haven't been able to find much helpful things online to help me bec

black bars covering taskbar sometimes half the screen

When my monitor refresh rate is set to 60, the black bar's height is lower but it still exists. When my monitor's refresh rate is 144Hz. It covers half the taskbar, yet when my laptop is hot, the black bar's height is lower. when I turn on the AC in my room, the black bar covers half my screen and sometimes half the screen stays in 1 frame and doesn't update. Please help if you even understand what I'm saying. (HP laptop, Intel display, Windows 10 preinstalled but I upgraded it to 11)

 

Problem with BLACK BAR covering bottom third of screen

A week ago on about March 14, 2016, Windows 10 automatically downloaded on my computer. The result is that Windows 10 damaged many of the features of my computer. I have managed to find a work-around to some of the damage that was caused by Windows 10,
but not the problem of the black horizontal bar. The black horizontal bar covers bottom third of my screen. A black horizontal bar about one inch tall resided at the bottom of the screen, shortly after Windows 10 installed itself. Then, I manually lifted
up the bar, using the mouse. But now I cannot make the black bar go down again. Truly, this is preventing me from doing my daytime job. The black bar that covers the lower third of my screen is about five inches tall. This is a severe problem.
