the Xbox 360 I have is the new one, but 4gb, so it has no hard drive. Anyway, since I got it, it works wonders, I went to a friends house, played it, then went back home, hooked it up, I hit the power button and all I hear is kind of a beep sound, but the sound it makes normally to turn on. Thats all it makes, gives no indication to anything else... Thoughts?
