I need help

[Shayne80]

I've got a persistant problem, it has continued through reinstalls and hardware tests.

The problem is this, my PC at random times just restarts. No warnings and nothing in the event viewer, I could be just watching youtube/netflix it restarts. I've monitored temps and they never go higher than 55c during gaming on ultra, it could restart playing Battlefield V or WoW.

My Hardware
CPU Ryzen 2700x under watercooling custom loop
ROG B450-f gaming with latest BIOS
16Gb's HyperX ddr4 3333
samsung pro 970 512gb
EVGA RTX 2070 ultra XC
4 x Samsung 850 pro
Thermaltake toughpower 750w


Here is what I've done so far.
I've memtest both dimms and I've run the machine under 8GB testing both sticks and it restarts regardless.
I've tried a 1070 from my other rig and it restarts again at random.

I havent' tried another mainboard or a different am4 chip as I don't have access to a spare.

So my main question is what tests can I perform to try and determine whether it's MB or CPU.

I thought it was a failing PSU, not supply the rails. I had an OCZ 750w and bought the thermaltake Toughpower 750w but I was wrong.

I've installed and reinstalled windows 10 with all updates, I have full AV installed I've cleaned everything.

My temps are 25-30c under normal conditions and 50-55c under load.
I've not overclocked the cpu, ram or the gpu.

I'm tempted to say the mainboard is cooky as the cpu would throw up other problems like controller issues and so on.

What do you guys think?

Thanks in advance

Mr Mcgoo, thanks for the info I've ripped it all apart again hoping to find a rogue standoff but sadly nope, cheers anyways.

Freddie, thanks for the reply, it's running at native 3333mhz although it is forced using the bios, it wants to set the speed at 2800mhz, I'll underclock it and see if that improves stability.

Once again thanks a lot, I don't consider myself a novice but this is making wanna go back to atari.

edit: Freddie, you may of figuered it out https://en.wikichip.org/wiki/amd/ryzen_7/2700x I need to run under stock @2933Mhz max. I didn't even think of checking the controller limits, thank you bud.

Just a follow up and a thank you, it's been a fair few days since I adjusted my ram speed and I can confirm that not one issue has been found. No restarts or crash's..

Thanks a lot Freddie, awesome advice.
