Sorry for flaming, but:
OMG, how can one be so stupid ? You should have known that there are some problems with the 360, how can you take it apart before even testing it ? When my 360 returned from M$' repair service I tested it for a whole week before taking it apart again just to make sure it is stable to some extend.
Well, the good thing is: You will never do this again will you ? Congrats, you just learned something.
Why even waste a moment of your life posting something so retarded?
