It is possible that Steam will ask you to enter a code, sent to your e-mail address, when you attempt to log in using a new PC for the first time this is a measure meant to protect accounts from being hacked and may be deactivated (not recommended).Īccording to Steam Support, you are either logged into the wrong account, or your filter is not set to ' All Games'.

You do not need to re-purchase any game you've bought previously, as long as you log in using the same Steam account you previously bought the game with however, you will need to download those games on the new computer.
