iATKOS v7 on Phenom X3 8450 - need help

[mrhound_004]

Hi,

I have a HP Pavilion AMD Phenom X3 8450 with 4GB DDR2-800 RAM and a NVIDIA GeForce 6150se.

I've been trying to get Snow Leopard and Leopard on my PC but I'm getting the Apple logo loop without smoking sign (not sure what that's called).

Any help is highly appreciated
