Late 2011 17 Inch MacBook Pro Not Booting, Three Beeps When I hold "C"

my late 2011 mbp 17 inch will not boot. In safe mode with verbose it stops at the point looking for my hard drive. Disk utility in single user mode said the SSD has "keys out of order" and could not verify disk etc.


However when I hold "c" aka trying to boot off my optical drive with Snow Leopard in it...it beeps three times, which after searching everyone seems convinced it's memory but I took out my upgraded memory that was in it and put the factory 4gig (2x2gb) sticks back in and it's the same exact thing...three beeps when holding "c".


If I hold nothing my computer shows the apple logo, the spining boot up activity icon, AND a progress bar at the bottom that get's about 1/6th of the way doing whatever it's doing and then it instantly shuts down.


Any other ideas besides the idea that my logic board that is 1 year old randomly stopped working? It's just weird that my 9 month old SSD is not being recognized while at the same time, holding "C" to try and call my optical drive to boot I get three beeps.

MacBook Pro, OS X Mountain Lion (10.8.2)

I understand it's supposed to mean RAM problems...the problem with that idea is that I have put working RAM in to my laptop and it still happens. I have put working RAM in both slots, alternate single slots and still three beeps. Again, this is working RAM tested elswhere.


It doesn't beep three times if I hold nothing down, but if I hold nothing down it just turns off. as noted above
