When I put a disc in my Wii makes a buzzing very loud noise.?
***** READ BEFORE !!!!!!***** OK this is not really a question about the same noise, but more about is it safe to set, whenever I put my old ps2 first generation at the top of my Wii the noise stops. Is the weight this ps2 is going to break my Wii? I had the chance to play Mario Galaxy very well for about an hour with this ps2 at the top too, but it's so bad for the wii?
I would not recommend putting two consoles at the top of the other. That is simply not a good idea.
