I been running a node for years and never had a problem that reindexing didn't fix.
I downloaded 0.14.0 and tried to reindex but about halfway through I got a error that said the database is corrupted.
I restarted the Bitcoin 0.14.0 client then I got a error message that said Unable to rewind the database to a pre-fork state. You will need to redownload the blockchain.
I might try reindexing on 0.13.2 if that doesn't work I might look for a backup copy of the blockchain so I don't have to redownload the whole thing.

HDD failing?
