I'm having a problem here and it's really bothering me!
I'm using a new model, 250GB XBox360 and I have been having this problem for a while now.
Sometimes when playing a game, the controller will just start vibrating constantly. That's pretty annoying, so normally I would turn the controller on and off again. However, after this, it no longer syncs with my 360, so I need to turn the console off from the mains. This happens with any controller that I use, so I know it's not the controller, and it happens when and when I am not using the plug and charge kit. It's happening quite regular now.
Has anyone else had the problem? Or now about the problem? I called the 360 support line and they said they will send me a new controller. I know it's not the controller though, as it happens with any I use.
Thanks for any help!
