Random black screen, whole system crashes, psu reboot only

I got the same issue here. But in my case, it not RANDOM, it always happen when the game is "Verifying Shader". 
P/s: The game was normal in beta, but ran into the same problem when release.

I5-11400F - water cooled
Asrock B560M Steel Legend  - bios P1.90
AMD RX 7800XT Sapphire Pure - stock, driver 25.9.2 (latest)
2x Corsair Vengance DDR4 3600MHz 8Gb RAM 
Super Flower Leadex III 850W PSU (Gold standard)

You've tried many good troubleshooting steps. When a computer hard crashes with a black screen and repeating audio in a loop, it's mostly likely caused by a hardware issue.

A RAM memory issue seems the most likely cause. Perhaps one of the memory sticks is failing and causing errors.

Try only plugging one RAM stick into the motherboard at a time to try and narrow down which stick might be faulty.

I've had good success with HCI MemTest finding memory errors.

Thanks Oskool_007, I will try removing the sticks one at a time - hopefully it's just like you said, as DDR4 is cheap nowadays...

I will update my post if I find a solution :)

I think I found an solution. It seem like I having some kind of power related issues with the mainboard and the cpu. Although, my cpu is an non-k version or it's cannot be overclocked. I follow the solution in the below topic, the crashing problem seem reduce. It's not the best solution, but I can play 2-3 matches before it crash now :D

oNerdheimer​ I'm glad you figured it out. Did the GPU come overclocked from the factory? Which GPU do you have?

7900xt et ryzen 5 13600kf

Le jeu est sortie et le jeu fait crash mon pc en écran noir et ventilateur a fond je doit éteindre mon pc et en le rallumant je doit désinstaller et reinstaller mes driver amd j’ai essayé plein de solution de Reddit mais rien à faire j’ai essayé de baissé les mhz max, désactivé le xmp de la ram dans le bios et d’autres trucs mais rien ne marche avez vous des solutions j’ai passé la journée a faire des tests et je perds espoir 

ethernityteam​ here's some things to try. The first thing I would try for 13th and 14th gen Intel CPU is updating the motherboard BIOS. It's known to fix that generation of CPU.

The PC is shutting down in the middle of a game? That's usually a hardware stability issue.

Try these steps one at a time so you know which one fixes the hardware crashes.

1. Update the motherboard BIOS firmware to the latest version.
2. Disable XMP/EXPO memory overclocking in motherboard BIOS.
3. Downclock GPU core and VRAM frequency by 200MHz.
4. Disable both PBO & CPB in motherboard BIOS if you have an AMD CPU. Disable Turbo Boost for Intel CPU.

If PC is still shutting down and crashing I'd check for memory errors with HCI MemTest.
