Pending OP Response Sudden restarts / black screens

[david891]

Hello,
I am hoping someone has some advice for the below issue I am experiencing.

Specs:
Computer Type: Desktop
GPU: XFX AMD Radeon RX 7900 XTX Speedster MERC 310 Graphics Card for Gaming - 24GB
CPU: AMD Ryzen 9 7950X3D Processor
Motherboard: MSI AMD MAG X670E TOMAHAWK WIFI AM5 DDR5 ATX Gaming Motherboard
BIOS Version: 1.E0
RAM: CORSAIR Vengeance 64GB DDR5 6400MHz CL32 Desktop Memory - Black
PSU: CORSAIR RMe Series RM850e Fully Modular Low-Noise ATX Power Supply
Case: CORSAIR iCUE 4000X RGB Mid Tower ATX Gaming PC Case - White
GPU Drivers: 24.12.1
Chipset Drivers: AMD CHIPSET DRIVERS VERSION 6.10.17.152

Description of Original Problem:
Since booting for the first time I had random restarts. Example was after click "install updates" on Windows Update both screens went black and computer automatically restarted. It also totally bricked when left on idle and once 5-10 minutes into playing a game it again restarted automatically.

Background Applications:
Chrome, Spotify, FS Dream Team Installer

Troubleshooting:
I have reinstalled Windows and left it on 12+hrs with no freeze. I was using Spotify, just installed .net framework and just just "install" to install a piece of software and again it bricked and automatically restarted.

On this particular restart the documents folder / downloads folder is missing. I can still access it via C:/ route but if I attempt re-pin it to a location it errors and wont do it due to disk error.

Does anyone have any ideas of a potential culprit? Would appreciate any assistance.

Hey, thanks!
I am starting to suspect that maybe one of the drives is faulty or it could be the PSU, as the issue occurs totally randomly. Even trying to recreate the crash/restart is impossible.

Further to above I have also updated BIOS to latest stable version 1.F0.

Update! I have swapped the PSU with an identical one, still the same issue.
It was idle for 5-6 hours nothing running, went to use it and within 2 minutes, black screen and automatic restart.
I am suspecting RAM or drive issue?

Have you checked the temps prior to shut down ?

The RAM is not appropriate for your CPU, AMD state here up to 5200MHz/MT/s and if you have EXPO/XMP enabled the RAM will get auto OCd past what the CPU can handle and the PC will become unstable.

AS a starting point;

Make sure that the Windows Power Plan is set to Balanced and not High Performance or Ryzen Balanced.

Restore the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" "most stable" or on newer boards "optimized" please note that if you have both the "most stable" and the "optimized" options in the BIOS you should choose the most stable" option as in this instance the "optimized" settings are a form of overclocking that can cause instability.
Save the new settings, exit the BIOS, restart the computer, test by using the computer as you normally would, post back with an update once you have done this.
