My 250 gb Xbox 360 slim has been randomly making the on/off and disc tray open/close noise when the Xbox is on and off. It will beep even when the power brick is in standby mode (orange light). It has been doing this for about two weeks now. I have tried cleaning the buttons with Q-tips but it still beeps randomly. It is not persistent either. It might beep once in an hour or twice in 5 minutes. It's just completely random! The buttons will also sometimes not work when I touch them. On 2 different occasions while I was playing my Xbox my disk tray opened without anyone or anything touching it. I have had this Xbox since it came out and have not had any problems until recently. Please someone from Xbox support email me at [Mod Removed - Please don't post your personal information on this public forum.] to try and figure out what is going on.
