Desktop background randomly goes completely black

I think there were already signs of this bound to happen when I noticed a while back that my desktop was refreshing randomly, but I didn't really make anything of it. I've done numerous virus scans with everything updated via Malwarebytes Premium and my own Windows Defender Program and it always tells me I'm clean. Now, my background on my desktop just goes black randomly and a way to fix it is to just refresh the background and my wallpaper comes back...Also, sometimes when I click and hold down my left mouse button and drag to create a box on my desktop, it'll create blackness instead of being transparent like it usually is and the black stays. Can anyone please help me? This is starting to bug me real bad. I have everything updated. Windows 10, my graphic card's drivers, everything. Really not sure what in the hell is causing this..

Not sure how to edit my post (can't find an edit button anywhere), but here's a photo of my screen black and me dragging my mouse cursor while holding the left click down. Apparently, I start removing the black by doing this and it reveals my wallpaper, little by little. It's so weird and I don't know what is causing this.
