Phenom II 550 and MSI 785GT-e63

hi guys,

I just bought a phenom II 550 and an MSI 785GT-E63 and I want to unlock it.

okay, I already updated the BIOS into latest version (though Im not sure if it supports ACC) using LIVE UPDATE 4 and try to unlock my the remaining cores.

I entered setup menu> CELL MENU> and I change the UNLOCK CPU CORE into auto and enable ACC.. when I look for the cpu core control and change it to per core it shows core0.... to core 3.

then I saved changes and reboot, unfortunately, it stuck on startup and POST won't show up.

My question is:

1. What is the main reason why my computer won't boot when I enable ACC?
2. Is there any possibilities that the problem is with the BIOS and not the processor since MSI haven't released any BIOS update for my board.

3.Is there other way to unlock it without using ACC?

THANKS in adance :) 
more power :)
