There is a weird hum coming from my wii when a game is in the drive. It doesn't always happen when the game is first put in, but usually starts up after a few minutes. And there is no weird hum when there is not a game inserted or when i am on a wii internet channel, and for this reason I don't think it is my speakers. My wii has never frozen, but I am a little worried that my wii will mess up or break later on down the road. Any help would be much appreciated.
