Stuck at Apple logo when trying to boot

[daraio]

Hi u all!

I am having trouble after installing SL. I used the iboot + multibeast guide to install SL 10.6 from an original DVD. After the installation, I runned the combo update for 10.6.7 and then multibeast using the DSDT from the database from this site, then rebooted my system.
After the reboot, it Freezes at the gray apple logo with white background. I tried booting with iboot and reinstalling multibeast after deleting the extra folder with no luck.
Does someone have any solution for this?

Pc specs
I5 2500
Gigabyte ga-p67a-d3-b3
4gb Kingston hyperx 1600mhz
500gb seagate sata3 (plugged in the blue sata port)

Thanks in advance!

Pd: sorry about my English, not my first language (Spanish)

Boot with the -v boot flag and post a pic of where it stops.

Sorry por the link, I am on my iPad.

Forgot to say I have a 9600gt VGA

Thanks for your help!

EDIT: My HDD is on blue sata2 port 2 and my DVDRW on the blue sata2 port 3. The ports 0 and 1 are the whites sata3. I don't know it helps but in the iBoot+MultiBeast guide it says "If using a Gigabyte 1156 board, use the blue Intel SATA ports- not the white Gigabyte SATA ports" and I'm not on a 1156 board, the 2nd gen Intel are 1155.
