Hello,
I bought a wii around a month ago, and it's been fine up until recently. When I put a game in, after a length of time it wil sometimes freeze the image on screen and buzz angrily at me. The wii will not respond and so must be turned off at the mains. I have only experienced this with three games (Mario Strikers, Twilight Princess and Mario Galaxy). The length of time before it occurs is anything between two minutes and an hour or so.

What should I do?
