Have you tried one NVME at a time? If it's having a problem with one drive or one slot then trying each drive in each slot by itself could help you narrow things down.
Nope it does not start after a bios update, i was thinking the same wether it is related to bios at first but then i tried to update the bios to latest version and it still happens. I tried to reverse to a old bios and the problem still persist. I have a spare processor to try too and it still gives the same problem. For now i already done a naked test which i remove all the 3rd party sleeves cables for 24pin, 8pin x2 for GPU, 4+ 2pin for MOBO CPU and use only direct cable from PSU for testing. The problem does not occurs after a week of testing now, and i have added a Thermalright HR-09 2280 heatsink on my Gen4 NVME SSD to cool down the temperature to 47-49'c compare to asus original nvme SSD heatsink the temperature is too high( 66-70'c ). Well do a storage transfer test to see if the problem comes back or not, if it still persist well i think the mobo is kind of faulty already.
