iATKOS v7 installation

Hi everybody, i'm what they call a newbie, so please be patient :) .
Here is my problem... i tried to install iATKOS v7 on my PC, and i followd this tutorial :

YouTube - Hackintosh Basics Tutorial (OSx86 Project - iAtkosv7)

Everything went good untill the end of the installation, after my PC restarted, the chameleon v2 screen came and launched the right partition, then a screen with the apple logo and a circle loader under it, after that i got a grey screen with a music (i think it's the music of the welcome video). After the music stoped....nothing.
So, I wanna know, what's the problem with that?, and what should I do to fix it?
Thank you so much.

My PC Config :


Mother Board : Asus P5B-VM SE
Chipset : Intel P965
CPU : Intel Core 2 Duo E4600 @ 2400 MHz
RAM : 4096 Mo (2 x 2048 DDR2-SDRAM )

Network card : L1 Gigabit Ethernet 10/100/1000Base-T Controller
OS : Windows 7 Ultimate Professionnel 6.01.7600

Is there anybody out there....?

Is this that hard to help me ??!!!

When chameleon showing your boot drive, press space and type: - x32 cpus=1 -f -v
post the screen result here, if you stuck again ....

Thanks for your reply....i m gonna try it, and tell you what's going on.

didn't work.... :( it's still doing the same thing (i can hear the music of the video, but still don't see anything but this f.... grey screen) :mad:
I don't know is this a graphic problem? i really want to install mac OS on my PC, should I install some other version? PLEEEEEAAAAASE HELP !!!
Thank you

It might be the video kext. But first, do some permissions fixing..and disk verify.
You can do it in terminal or with the disk utility. And then reboot with that option plus some "Graphics Mode"="1280x768x32"

Sorry but like I said : i'm a newbie.... I don't how to do all that stuffs, so please can you just explain to me how to do this clearly ? I know this must be boring for you but I really don't know much about that....
Thank you

You are actually very close to osx..

Go to kexts.com find your videocard kext there is alot there, but try one.
put that .kext file to osx volume /System/Library/Extensions folder

and try like this:
if you are sure that you have select the right kext for your video:
at chameleon screen, press space, type -f -s
when you are at the prompt, type: ..per line

/sbin/fsck -fy (*wait till it finish)
/sbin/mount -uw
cd /System/Library/Extensions
sudo chown -R root:wheel *
sudo chmod -R 755 *
sudo rm /System/Library/Extensions.mkext
sudo rm /System/Library/Extensions/Caches/com.apple.kext.caches/Startup/Extensions.mkext
sudo kextcache -m /System/Library/Extensions.mkext /System/Library/Extensions
/sbin/fsck -fy (*wait till it finish)
/sbin/mount -uw
Exit

thank you for your reply, just a simple question how to copy files to : /System/Library/Extensions when I can't make it even to the desktop of OSX ??
It might look like a silly question, but sorry I'm really a newbie......
Please reply to me tonight, so I can retry it today.
Thank you very very much
