Hey everyone,
I"m sorry if any of this sound noobish, because i am new to mac os x and I am trying to learn. Anyway, i am trying to install Snow Leopard on my computer:
Hp Pavilion Dv2940se

Geforce 7150m/630M
I'm unsure what MOBO i have
(If you need more info, which i'm sure you will, please don't hesitate to ask)

Anyways, I have downloaded the dmg for the leopard install, and i restored it to an install volume. Everything goes normal and I click the Install Mac OS X icon. It opens, and I hit continue, hit customize and select only the thing's i need. (the essential system software, and X 11, don't have any need for font's or languages, and i don't have a working printer.) i hit ok, and then hit install. It starts the installer for about 5 seconds and crashes back to finder. It says that the application install mac os x quit unexpectadly and give me the options to ignore, report and relaunch. I have tried all the options!

When I hit report this is what it says:
