Aorus z270x gaming 7 -

Yes, No problem with LED lights at all, my concern is from the beginning to 0:10, after I pressed the power , it will on, will off by a second and will turn on again.
 



It passed memtest, no error found. and i've updated it to latest bios. It still happens. I think it's ( avr / psu or surge protector ) , one of them could be the culprit.
