first try turning the pc completely off for a minute. Then boot back up and see if the drive is listed in the bios.
If it is then you likely need a firmware update for the ssd. you get it from the manufacturers site where you will find directions on how to do it also.
If its still not listed in the bios then check the power and data cables going to it, use a new sata data cable if you can. If its not detected after that then its most like a defective ssd. Hopefully it will still be under warranty.
