Alright so my Xbox 360 was working fine up until yesterday! I was playing Fallout: New Vegas fine but now when I try to play it ( and any other game I have ) it will say " Reading " and then after about 5 seconds it'll start making a weird cluttering sound like the disc is wabbling while it's inside. After about 30 seconds it'll start to make the " Yay I'm working! " sound but then it stops and it says " Open Tray ".

Now, I can still play Fallout New Vegas because I installed it to my hard drive and so I just start it up from the game library and it'll work. But I can't play any other games.

Anyone know how I can fix this? I don't have a warranty on my xbox and I'm to afraid to open it up.

Things I've try'd:

1) Lightly dropping the xbox to some how fix the tray ( key word is lightly, and it was on a padded carpet )
2) Lightly tapping the top while the disk is reading
3) Pray to God

Anyone got any other suggestions please let me know!
