I have an xbox, and I keep getting a service error of 13, 14 and 16. I formated it using xboxhdm, and still got the same errors. It would load after a few resets. I tried a working hard drive out of my other xbox, and it did the same thing. When it does load to the M$ dashboard, it shows the background, but nothing else. If I move the key pads, it makes the noises, but nothing comes on the screen other that the background. Any ideas on what I have done wrong? Is it maybe the mother board? I alos had the same dashboard problem when I hotswapped a dead HDD and replaced it with a working one.
