SSD that worked fine not showing in bios or booting anymore

[Jbub79]

I have a MSI z170a gaming M3 with an i5 6600k, 16 gig ram, Adata sp900 256 m.2 ssd and 1tb wd blue hdd. The ssd is set up as the boot drive. The other day my wife said that the computer was not responding and had her restart the computer. Since then the SSD doesn't show up in bios or when I try to repair the system through win10 setup. I have moved to hdd and dvd drive to different sata ports, flashed the mb bios to the latest version, cleared the cmos, and removed and reinstalled the ssd. After all that the drive still does not show in the bios. Before I take this to a computer shop to test I was wondering if there is anything else I can do to get the drive to show up. Or do you think the drive died all of a sudden?

Try connecting the sata & power cables from the hdd or optical drive (since they definitely work as those drives are being detected) and connecting it to the ssd. Do not change the port the sata cable plugs into at the motherbd end (we know that works also)
Power up and see if its detected in the bios now.

You could also try seeing if the drive is detected in a usb drive dock or drive enclosure if you have one.
