Ryzen 7 3700x problems

I have a problem and I hope to find a solution to this problem:
I work as a 3D Maya designer, and at the present time I am making a rendering of a specific scene, using Arnold for rendering.
Unfortunately, the device is restart when I do is render and I don't know why.
Note: I am working with the normal CPU cooling(stock cooling).
cpu ryzen 7 3700x
gpu gtx 1660 super
mb aorus b550 pro ac
psu aorus p850
I hope to find a solution to this problem.
This is a picture of the cpu and I'm doing a Stress Test on it.
But what is new is that when the pc doing the stress test the screen has blackened and back again in 2 seconds and opened it again, as like I am editing the quality of the screen, and of course the program has stopped, and when I run the test again, the pc turns off and restarts itself
Thank you very much01.png

Do you know the exact model of your PSU?


With the screen blacking, it sounds like a video driver timing out.

Is there anything special about your Monitor setup that puts you on the edge of norm?  

(Like Multiple Monitors,   Super High Refresh,  High Resolution, Running through a KVM switch, running audio through Monitor)

Do you have any messages in Event viewer?

Make sure you are not overclocking the Graphics card.    A good monitor for that is MSI Afterburner.

It may not be related, but it never hurts to run in-spec.   Do not run DOCP or XMP.   Accept the Timings as set by Jdec and run the memory no faster than 3200MHz


1: no thing special about my monitor setup, just working on 1280*1024.

2: not got any message from any thing about this problems, and I never use overclocking manually or by software.

XMP is working, I'll disable it and try again.

thank you



Isn't Gigabyte P850PM one of those exploding power supplies?

I Know your model has an "A" prefix, but too close for my comfort.

Anyway, I don't think it is your problem, but something to keep an eye on.


It's the GP-750GM that is the bad ones...  and the 850 version
