How to find out where the RAM consumption goes if it is not in the processes?

Question

Malware

This is very strange, I open the task manager, I have 16 GB of RAM in total, it shows that it consumes 20% when everything is closed!

I rummaged through the processes, I don’t understand where the leak is, scanned for viruses, anyway, Windows eats 1 GB, before the processes, well, another 1 max, and still they are not in the processes, where else did 1 GB go? How can you track where the spending goes if someone has installed phishing or hidden software for farming lightcoins?
This is suspicious, usually when it clogs a lot and I can’t remove it in any way, I interrupted Windows, erasing everything under clean. When clean windows, I loaded 5% -10% of RAM maximum, now 20% minimum.

Yes, it's not going anywhere.
Processes display everything that is in use.
It's not clear what the cost is.
