If you run diskpart > list disk in CMD, does it show the drive?

I am having the same problem however its my first ssd, I have W10 installed on a hdd and i also have another hdd for games. It doesnt show up in the BIOS the Device manager or the Disk Managment or Under my pc. Also, i dont have the m.2 screwed in atm could that be the problem?

That's a good possibility. It might not be making good contact without being screwed in.
