the M.2 NVMe PCIe suddenly stopped working

[Qscj]

I have a really weird problem...  I was playing some games and everything was smooth and normal in the PC

the next day I turned on my PC and this message appeared ( An operating system wasn’t found. Try disconnecting any drives that don’t contain an operating system )

 

before you suggest something

 

* here is what I have tried

- I tried to put the my M.2 in another PC ( I got the same message and the M.2 didn't work or appeared in the BIOS) 

- I tried to put my brother's M.2 in my PC ( his M.2 works, so the problem is not with the ports in my motherboard ) 

- I tried to look up in my bios to see if its appeared  ( nothing showed up ) 

- I Pulled out the CMOS Battery for 15 min and put it back ( didn't work )

 

any suggestion please, I have a really important data there

 

Here's my PC spec.

-CPU : Ryzen 7 3700x

-GPU: 1660 SUPER

-RAM: 16x2 CORSAIR VENGEANCE RGB PRO Series DDR4

-Motherboard : ASUS TUFGAMING B450

-HARD DRIVE : TEAMGROUP M.2 NVMe PCIe

pulling out battery doesn't work most of the time. turn off PSU, there will be two pins on the bottom of your board for BIOS/CMOS reset, short those pins.

Looks like you already tried everything, so it likely just died.

Looks like it may be dead. My sympathies...

Is the CMOS battery near 3.0 V ? Use a multimeter, might be just as simple as a dead battery.
