Hello, I have a problem these days with my Intel nuc mini.
4 days ago changed the background of my pc and when I turn it on I get a blue background with dots (attached images) also in discord some textures are wrong and in a game that I just installed called "Unturned" there are some glitch textures in the menu and in-game. These days I was looking for the solution, but I couldn't find it. I updated all the stuff and I think it may be a compatibility issue with windows or something.
I would appreciate your help.
You may restore your system to the Restore Point created before the latest change: How to Restore Windows to Restore Point.
Since your Windows is booting, you may try the Option Two in the above tutorial.
