Wii Hangs after starting game

Hi all, what can be the root cause hen the Wii hangs after starting a game?
Some games works fine, but others, after starting the game (it's being recognized by the Wii properly) the Wii hangs/got stuck and needs to be restarted. I checked of the relevant items so far. Could it be a setting related to the game itself? Thnks for your response!
