Hey

I have bought an Fatal1ty B450 Gaming-ITX/ac, bios 3.50

Ryzen 7 1700
16GB 8X2 G.Skill 3000Mhz
M.2 WD Blue 250GB SSD (are on the QVL)

If there is a M.2 installed, it wont boot.

When I remove the M.2 it boots up fine.

I tried til reset the BIOS, change Battery, change ram, change cpu, change gpu, change psu.

I also tried two others M.2s (WD Green 240GB and Samsung 970 EVO 250GB) still wont boot.

Nothing helps. Is the port DOA?
