Hi,M8 not 100% sure on this but my 360 had the same problem sort of...it would run about 1/2 of the loading logo and then freeze.. :evil: in the end I got a blank screen and FOUR RED lights around the power button... It was non modded at the time..luckly so I returned it for repair..I was told it was a internal hardware fault..??? which leaves the question wide open.. I looked on afew forums and it appeared to be a AV fault...

all I know is I got sent a refurb console..
Hope someone can shed some light on your specific problem..I might be barking up the wrong tree M8
