After Apple logo only grey screen

[flash.killer]

Hello

I want to install Mac OS X 10.6 on my HDD using my USB-Stick. But after the loading screen with the Apple logo I get a slightly blue screen which turns to grey and thats it doesn't load anything anymore. I tried various tutorials but I end up with the same problem.

 

My config is as follows:

MB: Asus P5Q

CPU: Intel Q6600

Graphics: Zotac GTX 260

 

Extra folder:

fakesmc.kext

PlatformUUID.kext

NullCPUPowerManagement.kext

IOAHCIBlockStorageInjector.kext

AHCIPortInjector.kext

ATAPortInjector.kext

AppleRTC.kext

OpenHaltRestart.kext

com.apple.Boot.plist

smbios.plist

 

I hope someone can help me how to solve this problem.

 

Thanks in advance
