PC shutdown randomly

[Vy-Ro]

Hi Guys, my new build keep shutting randomly down and the psu need to be turn off and back on to start again, i dont know why, i cant figure it out, i already tried to swap mobo ram psu (ssds and HD are from my old pc, never happened something like that, psu Also from old build but like a month old and even tried a new one) 

Components 

CPU: ryzen 7 2700x (running stock auto volt) 

CPU cooler : thermaltake floe rgb 360 

Mobo : x470 rog crosshair vii Hero (bios updated the moment i turned it on the first time (bios 0804 all running auto cmos resetted just for been sure) 

Ram : gskill trident z rgb 3200 CL 16 18 18 18 38 (supporter by the qvl of the mobo for second gen ryzen) 

Hdd and ssds :from old build not relevant because i dont get a bsod but it just shut off 

Psu : corsair rm750x 

Gpu : zotac 1050 (just a place Holder) 

 

It always shut down, no matter What. Some Times aids 64 last 2 hours some time not even 1 min, sometimes i can game on it sometimes it shutdown while Watching Netflix. I tried Also memtest86 and it passes it. I dont know What to do, the only thing that i havent tuched is the cpu but could a bad cpu do like that? Please help me Guys, i lost like a week on this and probably my mind to. 

 

PS: i tried corsair gskill and Asus support and was just a waste of time, always the person At the other end didnt even know What a second gen ryzen was and kept telling me that the cpu wasnt supported (obviusly not corsair they just Said have you tried turn it off and back on? Very use full)

That's rather weird. Never thought that Tech department support doesn't even know about 2nd gen ryzens.

I know this sounds silly but have u tried using other power cables and power plugs?

With power plugs you mean? 

And power cable yes i did with 3 different and 3 different Psu 

 

I mean the knew ryzen 7 2700x but when i Said second gen ryzen they linked me ths page of cpu support and told me not supported...
