There are two things which could be tried with the SSD
1. SSD's have some self healing capacities (discarding defect sectors) which are performed when the drive is not mounted. Therefore, enter the BIOS of the computer and let it running for ca. an hour. Then restart the computer.
2. After making a backup, do a "secure erase" of the SSD. Of course that needs reformatting the drive and rebuilding the system. I was able to revive a Samsung 960 Pro this way.
