Restoring the computer has nothing to do with accessing your iTunes account.
Logging into iTunes does NOT cause media to magically appear on the computer.
If there is data on the computer that you want, back it up before you restore the computer.
Do not come here complaining that you data is lost if you choose to not back it up.
