Windows 10: Icons have black square on them as I mouse over

I have an odd problem.

Desktop can look 100% fine, then as I move the mouse cursor over the icons, as I move the mouse over each one, they have a black square around them. It seems completely random when it does it.

Today it did it while installing a piece of software, then it had finished installing, the icons went back to normal.

Then a little later it happened again, no software being installed.

Very occasionally after this, the whole background pic turns to black.

Logging out and back in fixes it.

Paid for version of Malewarebytes gives a clean bill of health as does free Avast.

It's been doing this for a few weeks on and off. Yesterday evening I reformatted and reloaded Win 10. (well I reloaded from a trueimage disk image backup taken in May this year, then did win updates etc. has only been doing this for a couple of weeks or so)

Today it's still doing it. I just took a snip of part of the desktop after I moused over the icons,





Spec as in my profile

edit: I just removed a USB drive and this is the result





I'll log out and back in and it will be fine, sometimes when I just do thinks like browse web, open software etc it sorts it's self out

Any ideas?

Many thanks

:)

Black Squares On My Icons

Hello Everyone!

I followed a tutorial to the letter in how to remove shortcut icon arrows.

After restarting my PC I noted the icon shortcut arrows GONE!.

I SHUT DOWN my PC for the day and the following day when I turned on my PC I had BLACK SQUARES on my icons.

Don't know what to do. Can someone please help?

Thank you,

Carlos.
