my wii has froze a few times. for instance when i leave the wiishop and return back to the menu it will freeze and turn black instead of seeing the wii black blinking pattern, i see nothing but as if my tv was turned off.
happens also when i use the web browser
honestly it happens so rarely though that its not that big of a deal for really anyone to notice even myself. i just do a hard reset and then it works fine.
ill learn to deal
