How can I go about getting graphics working?

[bg4545]

After a lot of trial and error using different installs I've finally got Snow Leopard running.

My system is an HP Pavilion p6130y Desktop

Specs:

[cpu-z.png]

AMD Phenom™ 9750 Quad-Core Processor 2.4GHz

Memory (RAM): 8GB (I'm using "maxmem=4096" flag)

Motherboard: PEGATRON CORPORATION Model: VIOLET

Chipset: NVIDIA nForce 720a rev. A2

Graphics: NVIDIA GeForce 9100 (256MB) [integrated]

Audio: Realtek ALC888S [integrated]

Internet: nForce LAN and Atheros Wifi Adapter(Working)

 

I just haven't had any luck at all with the graphics. I've tried the enablers (NVInject, NVKush, etc.), as well as using "GraphicsEnabler=yes". but they just make the system reboot before it even starts. I want to know anything else I can try to get graphics working 100% or at least improved from how it is now.
