xbox 360's imho are not good systems. my friend had his for a couple months and his hard drive crashed and was on the phone with tech support for hours. From what I can remember I think he was having the same problem so you can try taking out the hard drive and restarting the system.
he eventually got the system working without having to buy a new hard drive by just taking it out but after doing that he couldn't save any of his games. Get a ps3, that's what my friend eventually ended up doing and just sold his 360. The ps3 is an all around better system, and once technology catches up it will dominate the new system market. besides blu-ray already beat out hd dvd in the competition for the next new media format.
