Ryzen 3700X Random Reboots, No Event Logs, Replaced Everything Except CPU

I have a brand new build (Specs Below) that is playing up. Initially, everything was great, after about 10 days things started going wrong.. I get random reboots with no warning, No event logs at all just Kernal Power / Unexpected Shutdown.

Everything inside the PC has been replaced for testing purposes but the problem remains and I suspect CPU is at fault.


Motherboard: Aorus B450 M

CPU : AMD Ryzen 7 3700X

Cooling : Thermaltake 280mm RGB Flo Water Kit

RAM : Corsair Vengeance Pro RGB 3200MHz, 32GB (4 x 8GB)

PSU : Corsair CS750Watt

GFX : Asus Radeon RX580 4GB Dual

SSD : M.2 Samsung Evo 970 NVMe 1TB


As mentioned I have replaced every single piece of this pc either under warranty or at my expense so far and the problem remains. Re-installed Windows multiple times with different releases and always the same issue


Temps are perfect, Sitting at around 35 at idle 60c under load.

The only thing I have found that helps is setting Ryzer Master to manual profile and setting everything to default with no power saving, Although it still reboots it lasts longer having it set this way..


On a side note, I can run Linux or Hirens PE all day long with out a issue, this only happens in windows 10 on any version from 1803 to 1903.


Any suggestions?
