Windows 10: PC freezes and black screen

I am having problems with my pc ever since last month. Sometimes, my pc freezes and then puts it in a black screen. Recently, it happened again while i was playing Elden ring nightreign.I've checked on the reliability monitor and see what it is causing it:I'd like to know what was causing this.

New laptop hardlock with black screen

I have a new notebook, running Windows 10 Fall Creators Update, which is randomly freezing, showing a black screen. System specs:

• intel core i5
• HD is an SDD, 250GB
• GPU: Intel HD graphics 620

Symptoms:

• happens randomly, related to no particular reason, time of the day, and programs running
• when freezes, the notebook screen is "active" (back light is on) but completely black; external monitor, connected via HDMI, is black as well
• when freezes, no key input is responding. I tried to press "CAPS Lock", which has a led on it, and the led is not toggling
• I noticed I can keep the PC on for several days, without any problem. It always freezes whenever I'm actively using it

What I already tried:

• reinstall Windows from scratch (even starting from an external USB drive)
• run windows in "clean boot" mode (all non-MS services disabled, all startup programs disabled)
• update the BIOS, and all "relevant" drivers (GPU, System Firmware, network interface, bluetooth, ...) of the PC to the latest version
• testing the memory with MemTest86+: no issues, after several steps
• stressing the GPU with FurMark: reached quite an high temperature (70°), but no issues
• stressing the CPU with IntelBurnTest: reached quite an high temperature (70°), but no issues

Now, I would guess it's an hardware problem, but the strange thing is that we ordered 6 identical PCs, and this is happening on 4 of them. Therefore, for "statistical" reasons, we don't think it could be possible that all of them shows an HW issue... It only happens with a different rate from one PC to another (for instance, happens daily on my PC, and once a week on another)
Any idea on how to investigate this issue further?
Any test / improvement I can do?
