Omen 16 blender and games crashes (squares artifacts)

[Spankej]

I have a problem with my new laptop Omen 16. When working in Blender the system freezes after some minutes and artefacts (small squares) show up on the screen and program not respond.

My first thought was that it's Blender's fault. But the same thing start happens when I play games.

It's not the case of system overload or overheating either because the problem occurs even when I do the simplest things in Blender, and temperature is normal .

At some point when I play, the game or blender freezes and artefacts show up on the screen - and the program doesn't respond and I have to swith it off via Task Manager. And waiting for it to respond doesn't do any good. At the same time the rest of programes and apps open in the background work perfectly fine.

My laptop is Omen 16 c0322nw
ryzen 7 5800H
AMD Radeon RX 6600m
16 Gb ram
Win 11 

I have the most up-to-date dreivers amd gpu (22.2.3) and I've already tried the old drivers - no changes, I install all drivers for omen 16 from HP site too. Windows System has all the updates. The problem doesn't depend on whether the laptop is plugged or not.

I've updated the Bios' drivers and tried to run the programes in backwards compatibility mode and as Administrator. Then I've reset the entire system back to the factory settings - nothing's changed. The problem still occurs.

I've played Hearts of Iron 4, Batlle Brothers and Kingdom Come Deliverance and the problem's occured only with Hearts of Iron 4 and Batlle Brothers (which have less requirements in theory). Kingdom Come's worked perfectly fine.

Do you guys have any ideas what could be the nature of problem?
