You don’t seem to have anything plugged onto SATA, which means the Kingston is your only drive (feel free to correct me wrong, but from that angle it doesn’t show another connection).

If the case has a seperate storage rack, check there to see if there’s another storage unit, like a samsung ssd. If not, it likely uses the Kingston M2 SSD as its only storage.

As for your next steps to save the PC, boot a live OS like GParted from USB, recover data if you can access the ssd from there to another storage medium, do smart tests to see if the SSD is faulty, and flash the OS you want to install if the SSD is fine.
