PC does not reboot or post normally

[CharredPancake]

Specs:

Mobo: Gigabyte X570 UD (rev 1.0) (New)

Bios Version: F12f

CPU: Ryzen 3 3300X (New)

RAM: Corsair CMW16GX4M2C320016 (New) 

GPU: GTX 1060 3GB(Known Working)

PSU: Corsair CX750(Known Working)

 

Problem 1:

if i dont connect any sata devices

and connect only keyboard when i press power switch it does not post 

if i clear cmos either by pins or battary it posts

and let me into the bios

it shows rams and cpu 

everything there is true exept it shows my cpu -55 degree celcius

when i try to exit the bios if i saved or not it does not reboots  cpu fan stops but other things works

and when i press power switch they all stops and when i pressed again cpu fan spins endlessly but nothing happens on screen

 

problem 2:

System does not reboots

if i press restart from start menu pc closes 

Cpu fan stops but system fans and ram rgbs still works but

Cpu fans does not work again and stays that way nothing happens at monitor

if i turn off psu and then turn on and press power button it boots but if I dont do that and try closing it with power switch and turn it on it does not posts 

if i turn off computer by shutdown if i press power switch cpu fan ramps up but does not stop and restart and mobo does not posts 

when i want to start the pc I have to close psu button and clear cmos then open it again then press power switch if i do that it posts and i can get into windows

but if i turn it off again i must do the steps again. 

 

Solutions i tried:

reseat every cable

reseat cpu, gpu

reseat ram

take one ram off and tried boot with just 1 dimm slot populated

tried every dimm slot

Cleaned Cmos

Reflashed bios

Cleaned cmos by taking off bios battary

Replace the green CX and the issue will go away.

Is the problem the PSU? but the system i was using before worked perfectly with it. it was fx-6300 and some generic low-end mobo.

Either the board or power supply and considering the green CX is notoriously prone to failure as it's an ancient rebrand of the GS series I would start there

That only makes it more likely that it has failed.
