Problem with IAtkos, Graphic driver cuts out on start up.

[Faithy]

Ok so first time installing mac last night, i got a P5Q pro mobo i flashed it with the modded bios enabled AHCI, installed IAtkos v7 10.5.7 and it all went smoothly, I have a GTX260 so i selected the GT200 drivers in the custom install.

 

Now when the the install finishes, upon the boot up, the display cuts out i can hear sound so i think its just a Graphic driver issue.

 

After getting annoyed off with it i tried install Ideneb only it coudlnt see my hard drives, so thats a no go.

 

Anyone know what the problem is with the display cutting out, i have tried googling but it wasnt much help.
