Earlier today I learned that some of my hardware was not compatible with windows 8.1, so I upgraded to windows 10. Since doing so every 30 seconds or so after signing in, my entire system shuts down unexpectedly. I am writing this and doing everything else from safe mode w/ networking. I have done three soft resets, two complete reformats and reinstallls, and the problem still persists. To my knowledge there is no overheating or other hardware issue as ive been running windows 8 o the same rig for almost two days. I really have no idea where to begin and am exhausted from dealing with this all day, please help.

OS - Windows 10 home (downloaded from MS website)
MOBO - Asus TUF b450 gaming-plus k3m0cs051725h4p
RAM - 16 gb forgot name of brand
CPU - Ryzen 7 2700x
GPU - GTX 660
