Question PC turns off while playing a game. I already replaced both Motherboard and PSU with brand new ones but PC still turns off ?

Hello, I have been having this problem for a week now. My computer has been turning off without warning for a week. At first I thought it was the PSU so I replaced it, then I thought it could be the Motherboard and I replaced that too. But it still keeps happening and I'm losing my mind now.

The RAM sticks were tested and are fine, so my assumption is now the cpu. But I don't want to purchase a part again without being 100% sure it is that part that has the issue.

My PC parts are:
CPU: Ryzen 5 5600x
GPU: Evga 3060ti FTW
PSU: Superflower Leadex III 750w
Motherboard: B550 Aorus Elite AX V2
RAM: Team Force Vulcan Z 2x8 3600

What BIOS version are you on for your motherboard? As for your platform, what OS are you working with? Might want to download and install HWMonitor to keep an eye on temps when the system decides to turn off.

My mobo is currently Ver. F14, OS is Windows 10
I am mostly unable to download HWmonitor because the pc turns off very fast.
But by looking at the BIOS temperatures, I don't see that's the problem.
