Question Computer randomly restarting without freezes, crashes or slownness.

Dec 21, 2020
Hey everyone! Hope u guys can help me.

Motherboard: Msi B450M PRO-VDH MAX
CPU: AMD Ryzen 5 3600x 3.8ghz
Cooler: Deepcool GAMMAX 400 V2
RAM: HyperX Fury 8gb 2133Mhz x 2
Drives: Kingston A400 SSD 480GB and Seagate Barracuda ST2000M008
VGA: Gigabyte RTX 2060 Windforce rev.2

CPU / RAM overclock: No
Overclocking: No
Where the PC is connected: Straight into the socket / I've used it with a extension.
Grounded : Yes

Operating system: Windows 10 Pro 64 bits.
Drivers: All updated via manufacturer's website.
BIOS version: B.60 - AMD AGESA COMBO-AM4 05/19/2020

Problem: I have a huge problem with my machine that has been dragging for a while. The computer restarts randomly with no error ... without crashes, slowness or anything like that. It simply black out and restarts regardless of what I am doing .. whether it's playing or idle it will eventualy turn off. The time between shutdowns is also random, and can occur after minutes of each other or even hours (like now that the PC has been on for 4 hours without problems)

I don't remember exactly when the problem started but i I made upgrades in some parts (I changed CPU, GPU and Motherboard) in the hope that it would solve it and the problem disappeared for a while (3 months or so).

What I've done:
-I've formatted the SSD and HD countless times;
-I started using Windows on the HD without the SSD plugged into the machine and vice versa;
-I tested a second PSU that I have here(500W);
-I changed the slot memories and tested each one separately;
-I disconnected all the fans and left the computer on without connected peripherals;
-I tried other outlets in the room and in other rooms of the house;
-All temperatures are OK;
-Memtest did not report any errors in the memories;
-I checked all voltages and they are all OK.
- * I didn't update BIOS for fear of the computer shutting down during the process. *

After doing all this the computer continued to restart randomly.

When you upgraded the system with new parts did you do a clean install of the latest Windows 10? You are not trying to install a 4 years old Windows 10 on the new system?

What is that 500 Watts PSU you tried? If the PSU is as low quality as your Corsair GS it could still be the PSU.

Power issues like that normally is the PSU. When it's not the PSU it can be the board or overheating. Could be other things too but I would start with a good model PSU.

What BIOS version are you running right now?

I did a clean install of windows using the latest version available at microsoft website.

The 500 watts PSU is an EVGA 500W 80 PLUS WHITE.

Regarding temperatures, im always checking them while gaming, idle and stress testing the computer and all of them are Ok.

I dont think its motherboard related because i had the same problem using my old parts ( i5 6400 and gigabyte B150M-D3H).
