Gigabyte X570 Aorus Pro Motherboard not working anymore

[Arizona]

Hi,
Last week I bought a new Gigabyte X570 Aorus Pro Motherboard for my Ryzen 7 3700X CPU and with a Be quiet Dark Power Pro 11 PSU. All worked very fine for 6 days untill today. Suddenly it shut down.

After trying to start I am hearing one click from my PSU ( starting ) and within about one seconde another click from my PSU ( stopping ) . That's it , nothing more, not even a fan.

I disconnected all my HDDs and SSD's, Video Card but nothing helped.
I placed the PSU in another PC and it is working fine.

Does anyone having any idea what I can do more?

Thanks

flip the psu switch to the off position but leave it plugged in, unplug the cmos battery - leave it unplugged for 3-5 minutes. plug it back in turn the psu back on, try to power it on. pay attention to the rgb light on the backplate shroud, i noticed on mine with bad bios settings that the it wouldnt power on but the rgb light was faintly flashing. following this process should hopefully get you back up and running aslong as it isnt a hardware issue.
