Question Intel M.2 disappeared after BSOD (critical process died) and reset BIOS

Dec 11, 2019
Dear all, thank you for reading this.
My computer is Asus ROG Maximus VIII Gene (desktop Intel Core i7-6700 @ 3.40 GHz). I used Intel M.2 240 GB (Model: SSDSCKJW240H6) for drive C (Windows 10 Pro) and Intel SSD 535 Series 240 GB for drive D. Recently, I've been getting a lot of BSOD (critical process died). Other times I get the "boot device not found," and I have to restart my computer several times (sometimes reset BIOS) to pass this message. Intel M.2 240 GB (Model: SSDSCKJW240H6) disappeared after I have to restart BIOS several times. I tried to update the BIOS (M.2 still not detected) and locate M.2 in device management, but I cannot find it.

I tried to open BIOS, select Advanced\Onboard Devices Configuration but only found:
HD Audio Controller --> Enabled
PCIEX4_1 Bandwidth --> Auto
Asmedia USB 3.1 Controller(USB3.1_EC1/USB3.1_EA2) --> Enabled
Asmedia USB 3.1 Battery Charging Support --> Disabled
USB Type C Power Switch --> Auto
Intel LAN Controller --> Enabled
Intel PXE Option ROM --> Disabled

  1. How to configure UEFI BIOS Asus ROG Maximus VIII Gene for Intel M.2 240 GB (Model: SSDSCKJW240H6)?
  2. Is there a way that can help me to make the disappeared drive C (Desktop, My Documents) show up again?
