My Wii sometimes freezes.

It only happens with wii play when 2 player option is selected. None of the controls on the box or the remotes do anything and the only solution is to turn it off at the wall.

The wii was not used for a month and when it was used again the game worked on 2 player for 2 sessions but has now started freezing again. I'm going to try turning the wii off completely for a couple of hours and see what happens.

Any other suggestions gratefully received.

Thanks
