My xbox 360 creates a small ring around the inner ring of my disc on every game I play. However the games all still work fine. However every so often my xbox 360 use to open tray. Now the xbox 360 everyday goes open tray when I restart it and i must reopen the tray and off for around 30 minutes - 3 hours or more and it finally reads the disc. However during the process of the reading I hear the laser making a rapid swiss sound. When I reopen the tray the game hasn't changed position not spinning. I am using an xbox 360 original white from 2008. It does this for every single game I play. I am saving my money up and I can't afford repairing or replacing my xbox 360. Im assuming the warranty is already expired. Is there any basic cleaning reqired or is it unreparable?
