How to find out the reason why a new laptop hangs tightly?

Question

linux

I bought a new laptop Asus VivoBook (Ryzen 5, Radeon, 8 gb, 250 ssd). I installed a fresh Kubuntu and during the day the OS randomly freezes: either while watching a video, then in the browser, then in the IDE. Depends heavily. Sometimes you can move the cursor. Sometimes even she can't. Ctrl+Alt+F2 etc doesn't help. Saves only reset. In one working day, it can hang like this 3-4 times.
So I started doing it when I installed a completely fresh OS, I didn’t install a single program other than the browser. So it is still. Installed drivers and updates.
Actually, no one here has a crystal ball. But at least tell me what logs to look at and in general in which direction to dig? I am not like a fish in water in Linux. If all else fails, I'll just try ubuntu. Then windows.

Answer 1

Check out UEFI. If there is a setting "C-State Control" - try turning it off and see if the freezes stop.

Answer 2

Seems to me that the entropy daemon is not running... Try it.
sudo systemctl enable --now haveged
