ASUS ROG STRIX B650-A GAMING WIFI M.2 BAY BOARD PROBLEMS
Symptoms of Defective M.2 SSD Bay:
1) System will post or initialize and go nowhere at the initial post screen and all you can do is do a force shutdown by holding down the power button for 5+ seconds.
2) System will boot directly into the BIOS where it sometimes will display your SSD but not show a bootable device in the "Bootable Boot Device"
3) System will sometimes post into Windows but the booting process from the Asus splash screen to the desktop will take a long time to get to.
4) If you are restarting or rebooting from the Windows desktop, the Windows will either boot and go nowhere or boot back into the BIOS.
