[SOLVED] New system randomly shuts down.

[rob.green615]

I bought a new system because my old build started randomly shutting down. So I got new components and the exact same thing happened. PSU failed the paperclip test so I bought another one and now, 2 months later, I'm back where I started.
I was just getting ready to install Windows and while in UEFI it randomly shuts down. Starts up about a minute later for about 10 seconds and again...

System specs:
Ryzen 5 2600
ASRock B450 Pro4
Corsair Vengeance 2x8 GB 3000 MHz
Corsair CX550M
XFX 590

Used from old build:
Crucial M4 128 GB 2.5" SSD
Seagate Barracuda 1 TB 3.5" HDD
Cooler Master Elite 310 Mid tower
Some Asus DVD reader

That didn't help.
Once I flipped the switch on PSU, it turned on for 2 sec and off again. And power button didn't start it again.

I have completely taken it apart and reassembled it like 4-5 times now with no prevail. I had the same problem with old parts but it happened only about once a year and worked perfectly fine after. Since I have tried both drives individually and failed both times, could the problem possibly be in the case?

to made sure it is not the front panel switch unplug it from board and gently touch the 2 pins momentary to se if system boot pus under power without flipping back swithc on it on and off .
