My Wii has crashed on my about 3 times now, nothing to major though. I do have this problem where, even after sync'ing my controllers, I turn my Wii off and my the controllers I was using at he time stay on. It doesn't happen all the time, just once in awhile. I would say once every one-two weeks. I can't turn my Wii back on from my controllers to turn them off, and I have those gloves for each controller so it is a pain to uncover the battery pack, but I have to end up holding the power button on the Wii for about 5 seconds to boot the Wii up and then shut it down without using controllers. For some reason, It will work after that, but I have no idea what causes my Wii to do this. I have 3 controllers, waiting for WiiPlay for my forth.
