Gigabyte X58A-UD3R rev.1 wont post when AHCI is set to enabled

[jucca]

Hi all.

Have very strange problem here with my Gigabyte X58A-UD3R rev.1
Installed a month ago, everything worked flawlessy until few days ago.
After powerup, my computer hang at post screen just after SSD (Kingston V+ 64GB) is going to been recognized. Tried changing cables and Intel SATA port, even flashed latest BIOS (F6) but nothing happend. 8/10 times it hangs at post screen. When IDE mode is set, computer boots, but not every time. Now it hangs at "veryfing DMI pool".
Have checked SSD into other computer in both AHCI and IDE mode, and it worked everytime. Tested other HDs and memory, and they're OK.
Please help.

rest of system is:

Kingston GSkill Trident 2000MhZ
SSD Kingston V+ 64GB
1TB WD Green
1TB Samsung F3
Corsair TX650W
H50 @ 2xNanoxia F1200
Sapphire 5850
packed in Cors 800D

I had a c2d mb that would stop after the boot drive do to a bad wd 2nd drive.
My bad wd hd would cause 2 mb to freeze at start.
I would remove all but boot drive and take it from there.

Bad optical drive?: try disconnecting & see if machine boots without it.
