Active windows hang in Win10, glitch, hardware or virus?

Question

Windows

Good evening everyone! I can’t deal with the laptop, the problem is this: In Windows I can’t close active windows (Explorer), I also can’t go to the start menu, I hover over, click and no reaction, it doesn’t even highlight the hints when I hover over the close button " or "start". On the desktop, everything clicks, but when you go to "my computer", you click on the disks and no reaction occurs. It's the first time I've come across this. I tried again: kill Windows, cleaned the laptop from dust, changed the RAM strips in places, plus checked them with MemTest86 - all the rules, drove the hard one through Victoria - all the rules, scanned for viruses, also a pancake - the norms. What could it be??? I've been scratching my head for two days!
