Problems with Asus M3N78-VM mobo

[Apoptose]

Hey!

I just tried to install iAtkos v7 on my desktop pc with a tutorial from insanelymac.com. Everything worked fine, but suddenly the installation stopped and I got a kernel panic. I made a photo of this...



Does somebody know what happened? I tried to use the onboard NVidia 8200. Should I buy a different video card like a 9500GT or something like that?

Thanks for your help!
