I have an XBox 360 S, and both yesterday and today when I turn the device on, the splash screen loads and just sits there. I cannot play any games or load the dash. I have tried clearing "something" by holding the sync button when booting the device, but to no avail. I smashed my old xbox 360 with a hammer after it quit working (I had it for 3 years and made numerous self-repairs). I've had this XBox 360 S for less than a year and it's already giving me problems. What can I do about this?
