Used to do it every few days or so and it'd usually do it several times in one gaming session. Wii would freeze, make a constant high pitched buzzing nose and not respond to anything. Only way I could restore it was to disconnect power. Not done it for quite a few weeks now, and up until then it seemed to be doing it less and less. I don't ever remember it doing it in the daytime, only at night (9pm onwards, GMT) and it never spazzed out on Campain Mode. Read somewhere it was likely to do with Wii processor chip not being able to cope with very high demand situations and most often it would freeze on me when there were several players on screen with lots of explosions, so maybe they were right.
In case anyone's curious, got my Wii Feb 2010, it's generally on it's side though I've had it upright and that didn't seem to make any difference to the regulatory of crashing, it doesn't do it on any other game, got Black Ops and did the old Wii update thing beginning of this year but it would never connect to internet for some reason..... I much prefer goldeneye anyway!

I believe that about the explosions because I was with a hacker and everyone wwas shooting at him while he used his grenade shooting anova and the whole map was in fire and my wii froze so I think that could be it

i think explosions are sometimes to much for it to handle because thats when it usally freezes for me oh and when the game ends right before scoreboard comes up that pisses me off because you waste that time and dont get the xp at the last second

That happened to me once. So annoying.

yeah i know

My game freezes every once in awhile. The worst time though was one it froze when I was about to win a team match and I was first in my team.

Well, reckon I gave my Wii the kiss of death when I posted about not having problems with game freezing/crashing the other day! Did it loads of times yesterday to the point where I gave up and switched it all off.
