So the other day I decided to play my xbox after not playing it for about a year, and when I tried to turn it on, the power button didn't work at all, but the open tray button did. so I started to turn it on again with the open tray button, and it started to turn on and whir, then abruptly stopped. I tried again and it did the same thing. I kept trying until it opened the disc tray, then it stopped and closed it. so I tried again and caught the disc tray before it stopped again, and then it worked perfectly fine, until I closed the disk tray and it stopped. it seems that it doesn't work when the disk tray is closed. so went to look up what was wrong with it on the computer, and it turned on by itself, with a game inside and the disk tray closed, but it didn't play the game, and completely reset. I tried to open the disk tray, and it turned of again.
