Snow Leopard Won't Boot on ASrock mobo #iATKOS

Fairly recently I built a computer with an ASrock Mobo and an Intel Pentium D 3.4 Ghz processor. As for graphics, it is just the onboard 8mb card. There is 2 GB of RAM. So I wanted to run Snow leopard on it, and I have on a netbook before, but when I try to load SN, it just sits there with the apple logo. This happens with Chameleon RC 3 and 1. Chimera and iBoot don't work at all. When I try to boot in verbose mode, it shows a blank screen. If I try legacy bootloader for 10.6, it gives a kernal panic. Does anyone have any ideas?
