Hi, First off, forgive me if I make any assumptions or misconceptions, I don't own a mac.
On the three attempts that fail to boot, does the POST display at all? If not, then a single long beep (on PC architecture) is a key indicator of a hardware fault. My advice would be to remove all internal hard drives, reseat any cards/modules (ram, gfx card etc.) Then boot. If that works, add the HD in and test, if that is reliably booting, then try the ssd, if that fails, take the HD out and try the ssd on its own.
