Windows 10: Desktop turning black & black squres behind icons

When I do a selection (click and drag) the space that I selected turns my desktop background black.

When my cursor goes over an icon, a black square appears behind it.

Also, when I drag an icon around on the desktop, all of the background turns black.

All of this started happening after I pressed a lot of keys at the same time by pressing the keys with my whole hand. I've looked for it on a lot of forums already and I tried every solution to similar problems but it never worked.
I really need help! Please.
I don't know if this can be usefull but I don't have a Windows key so Windows isn't activated on my computer.

And here are my specs if needed:
GPU: Gigabyte Nvidia GTX 1080ti 11go
CPU: Ryzen 7 2700X (not overclocked)

Ram: G.Skill Ripjaws V 16go DDR4 2666Hz

Motherboard: MSI x470 Gaming

Desktop Shortcut Icons Are Black


All of my desktop shortcut icons have turned black.

I first deleted my Explorer thumbnail cache and then my icon cache. I did not get the icons back to normal until after I deleted the icon cache.

But after I shut down and restarted the black icons were back. I went through this twice and both time they came back after I shut down and turned the laptop back on.

How do I get rid of these black icons permanently?

 

Desktop Shortcut Icons Are Black


Thanks, but same results. That gets the icons back, but when I shut down and turn the laptop back on the black icons are back.

 

Invisible Icon on desktop turns black


There are no 'truly' invisible icons in the Windows system, you need to search the web for one.
(I think they're created from a completely transparent bitmap image, then assigned an .ico extension, or sumpthin like that, I can't remember!)
