my son's xbox 360 gave ring of death without telling me he rapped it in a towel(stupid I know) it comes on fine now no red lights loads games BUT after about 5 mins it just freezes. No error messages or red lights nothing at all. would this be a dry joint/connection problem or has he cooked a damaged something?? is it repairable i.e x-clamp repair method
