Damnit
My 360 packed up last night as well, was working fine til I tried the Dead Rising demo but then it froze. Now when I turn it on I just get 3 red lights.
I've only had this 360 for 3 days! Plus it's the 3rd one, after the other 2 had faults.
I don't know why they keep breaking, I have it stood up with plenty of ventilation and it never gets knocked about.
I'm going to try to get a refund this time, as if I'm going to be on the 4th one after 8 1/2 months then what are the chances of it not breaking in 3 1/2 months time. Might as well buy another one, and get a new 12 month warranty.
Can't believe how easily these things break, I know it's a lot of powerful technology for a couple hundred quid but the damn things still need to work!
