Might go looking for corrupted hard drive one day but as far as I know it's well cooked. It was pulled apart & in pieces last time saw it after a computer dude tried to boot it & said mate this thing is toast.
Bitcoin core (bitcoin QT at the time) did not use recovery words.
Private keys are contained in the file wallet.dat, and this encrypted file is located in a separate directory from the bitcoin client.
The only chance left is hardware recovery of the hard drive. If you still have it, write me a PM
