Question Computer turns off randomly and then it doesn't turn on

[AndrewYNC]

Hello! I have a problem. My computer turns off randomly after a few hours of running but RAM RGB is still on. I can't turn on it after this happens, I must unplug it and after it turns on and the problem appears again after a few hours.
These are my computer components:
CPU: Ryzen 5 3600
MOBO: Gigabyte X470 ULTRA GAMING
RAM: Corsair Vengeance RGB PRO
GPU: MSI RTX 2060 Ventus
PSU: Super Flower 550W 80+ Silver
SSD: Intel 660p 1TB M.2
COOLER: Deepcool GAMMAXX L240 V2
Thank you for your help!

Are your temperatures of CPU in place?
Download HWmonitor and check them.

Can someone help me? It happened again today. I have latest BIOS version and latest GPU drivers so they are fine.
