user44117: I tried to install Bitcoin Core on my PC. The synchronization was not completed when my computer crashed. I am unable to restart it.
I had bitcoins in the wallet already. I have the Bitcoin address but I don't have the private key that can make the funds spendable. How can I obtain this private key to move the bitcoins to another wallet without having to repair my computer?

First, backup your wallet.dat file (if you don't know where it is stored, check this: https://en.bitcoin.it/wiki/Data_directory)
Analyse the crash, read the error message.
Quit Bitcoin-Core, try to temporarily move your data-directoy and let bitcoin-core create a new one.
Quit Bitcoin-Core, replace the newly created wallet.dat file with your old one (after you made a backup)
Start Bitcoin-Core again
If you don't want to wait until your full-node is synced (can take a couple of days), export your private key by opening the Development Console (ctrl - D in 0.13.0) and type dumpwallet <path + filename>
