Hi Benhermies,

Welcome to infinitemac forum, enjoy your stay and have a good time here!

I guess you already explored some sources on the net and searched for the solutions. Lets focus first on your desktop machine. Isn't your board a gigabyte's one? If so, what model? Will you look into your documentation, cd's with drivers for your exact model number? If you can't find it you can open side panel on your computer's case and take a look at the board, there should be its name, revision number. There is a very similar board from gigabyte, ich7 chipset. Your configuration looks very promising, even for perfect, retail installation. Let us just see what you have inside, what's the motherboard.
Running OSX on PC hardware isn't a rocket science ;-) with compatible hardware it's pretty easy; but it requires little of hardware knowledge and some basics in terminal commands under OSX etc.

Regards!
