Have the usual steps of resetting PRAM and SMC been taken?
Found this page with a Google search. It might help: http://www.techradar.com/how-to/macos-1013-high-sierra-problems-how-to-fix-them
And this page: http://osxdaily.com/2017/10/14/troubleshooting-macos-high-sierra-problems/
Maybe something on these two pages will help.

Do you have a backup of your files?
If it were me, I would first run diagnostics on the machine (hold the 'D' key at startup) - if no problems are found, I would then attempt a fresh install using a bootable USB installer (which is why you need to have your files backed up as everything on the hard drive will be deleted.)
Before doing a fresh install, you could always try the PRAM/SMC reset, booting into safe mode (hold shift at startup), and repairing the disk with Disk Utility (hold 'R' at startup) - however, if this is a brand new installation, if it were me personally I would just rule out hardware failure and then proceed with a fresh installation.
If this is a mid-2012 13-inch Unibody, have you ever had the SATA cable replaced?

I think ZapNZs may be onto something (post above).
If it's a 2012 MBPro (non-retina), the internal SATA drive ribbon cable is prone to failure.
When it fails, it will look to the user as if the drive itself has failed -- but it's really just the cable.
If you are anywhere near an Apple Store, take it to them and ask them to check the cable. They may even replace it for free.
If you want to try replacing it yourself (VERY easy fix), go to ifixit.com and look at the drive repair guide for this model.
You can get the cable part number there (it's not expensive), and buy it from them, or get it online, etc.
