THE XBOX 360 WILL NOT TURN ON

My Xbox will not turn on. I have more than 1 and I plugged another into the same plugs and they work. I looked on MS website and one thing they said to try is manually eject the drive to take a disk out. I haven't done this yet but will try. I think my power box on the inside of the is shot and will probably replace it with another one from another Xbox. I recommend finding one on fleabay that is broke and buy it for a low price and doing the same thing if you are handy. You may even be able to take one out of an old computer, but I would do some research to see if that is possible.

you may need a new power supply, i would take it back to the shop u bought it in with a reciept or some form of ID and they will help u, did u have any prior warnings? such as red lights or the screen kept freezing?
