Are you sure you have the correct motherboard key? Did it play games before you messed around with it or did you buy it from someone? The system will still play dvds without the key.
I got it off ebay, and it started up fine to the dashboard, but being in such an excited hurry as I was, failed to test a game in it. Though I have flashed the original firmware back to it (I've got it saved away) and no luck playing games still.
