I need help whit WHEA-Logger id 18

[KevinBogard]

Hello everyone, the thing is like this, a few days ago my PC restarted out of nowhere, no matter what I did on the PC (games, browser, etc.) it still restarted, everything freezes and restarts, the question is I have already done performance tests taking the CPU and GPU to the maximum for a couple of hours and nothing happens (everything always monitored in HWMonitor), the temperatures are stable, they do not exceed 55-60 ° C and also makes a A couple of days the PC was thoroughly maintained, everything is clean and with new thermal paste, when it restarts I go to the event viewer and I always get 3 errors called WHEA-Logger id 18 that you see in the image, now I do not know what that error means, it tells me that it is an uncorrectable hardware error but as I said all the components were stress tested taking them to the maximum and still it does not restart and nothing happens but when I am calm on the PC it reboots
I suspect it is the power supply but I want to know if you have any ideas.

 

Components:
AMD Ryzen 1400

Motherboard Aorus B450 pro wifi
16GB ram XPG
GTX 1050ti GPU
Corsair CX 450M
2 1TB hard drives
2 SSD 120 GB and another 128GB
Windows 10 64bits

 

I hope you can help me because before changing or buying something I need to know exactly what happens or which component is the one that fails.

 

I apologize for the English, I am using a translator.

Turn off "Low current idle" in BIOS. SShould be set to "Typical current idle" for Summit Ridge.

It's probably an error in the infinity fabric when the cores are trying to communicate with cache. If you have XMP enabled I would try turning it off.

then is it possible that the ram memories are damaged?
and I'm going to do that to see what happens
