I thought I had managed to miss the "360 return to m$ for repair" crowd...
Manufactured in the 1st wave on 20/10/2005 I have had no problems at all until now when my 360 freezes in Fight Night , Oblivion etc after only booting up - Hell it froze on the boot screen!
So all you owners of the first wave watch out for freezing with no graphical corruption and no red lights - m$ have asked me to return my 360 for repair/replacement.
Hopefully they will give me a "new batch" 360
You have been warned........
I think I may be having this problem, I've got a first wave 360 and have had no problems whatsoever, then tonight I start ripping music to the hard drive and then put fight night on.
I open the guide up then have a look at the voice options, changed the voice volume then went into the "notifications" screen and turned off Notifications, at the very moment i turned them off the 360 threw a wobbly and froze, had loads of grey blocks on the screen.
Now it's only a matter of minutes before it does it again, i'm not getting any "ring of light" errors either, so is it the same problem as you encountered?
Also by sending the 360 back does that mean I lose all music and Live arcade games? can I back them up to an external HD?????
any advice appreciated!
