Had the same problem .... fans running, dvd spinning, sleep light glowing, no chime/no start. tried all the fixes here and whadayaknow Tomas Jones, Feb 16 2012 fix made it boot! That was holding down the cd eject key while (trying) to start up. The DVD ejected and it started on the HD. Then I turned up the muted volume and restarted and it chimes!
