PC rebooting after launching Uboat

[[LSK] Andreas_Gemini]

I launch Uboat, playing it with couple of minutes? then quit the game. And then I start game again? my PC is rebooting.
Also reboot may happening then I press Headquarters button? or quit to main menu/ Has someone it? What is this?
PS: fortnite and MW looks stable on 2K 120 FPS

Hard reboots (Immediate with no OS warning) are usually a sign of:
Over heating - a critical temp is reached and the computer forces a hard reset to protect components
Hardware faults - a component has a hard fault that is causing the computer to do a hard reboot. this could be anything from Ram, HDD, SSD, PSU, Graphics card, Mother Board...

Soft Reboots (OS Safely shutdown /reboots) are a sign of:
Hardware / Software Critical Temp reached and purposefully halting the machine in a controlled manner usually a configuration in a Temp / OC Monitoring Software.
A numerous list of Software/ OS cause soft reboots.

Check your system temps with a monitoring program. run a stress test like prime95 or Graphics Stress test to test system stability. This game is unoptimized at this stage of development and can cause components to be over utilized and over heat.

Check your system event logs to see if the OS is capturing the reason for shutdown.

congrats on the find and resolution! honestly as mentioned by others in the community, uboat can really push our hardware, and that can quickly uncover issues with a PC that were previously unseen. 'F' for your old PCU. All hail your new PCU!
