For days, I can't figure out what is going on with my PC/Ubuntu 18.04.
GPU: GTX 1060 6GB
OS is installed on Kingston A1000, M.2 - 480GB
RAM: HyperX Predator 16GB (2x8GB) DDR4 3000 so I think HW should be more than OK.
The Ubuntu freezes for short amounts of time (like 0.2 sec), I can see it when I'm writing something (it freezes for moment) or when I scroll in browser (sound starts crackling) or even sometimes when I copy text to clipboard.
I noticed that even scrolling on website increases CPU usage to almost 80% but not sure if it's the problem.
Or - when I started libre office, sound was crackling for some time (0.5 sec).
I have 3 FullHD monitors connected to my GPU - 2 monitors and 1 TV but I it happens even without TV connected - 2 monitors.
SSD I have 335 GB free from 480 GB.
RAM is not a problem probably:
Throttling because of temperature is unlikely:

lscpu returns very different values over time but it is capable to reach higher frequencies so it is not problem too:
Stepping: 10 CPU MHz: 3167.816 CPU max MHz: 4600,0000 CPU min MHz: 800,0000 BogoMIPS: 6384.00
Almost all GNOME extensions are off:
I run out of ideas, do you have some?
