no worries mate. You'll get through this eventually. I was in your shoes about a year ago. I owned a PC but also went and bought a Macbook. After using my Macbook, I found myself going to my Windows PC less and less until I finally just needed it for work. Now I solely use OS X... with VMWare Fusion of course for the work requirement.

It may sound sucky but to really make your system work well, you may want to backup your Windows files externally and then reinstall completely over your main HD. If you have an extra HD lying around, it may be better to just install OS X to that one only for the time being until you find out exactly how to make your system work. The BIOS should still give you the option to boot to a specific HD (which you can select between reboots).

What kind of other Hardware do you have in your computer (besides motherboard, you stated that already)?
hint: go to "About This Mac" and "More Info" to get to System Profiler while in the install DVD to make a list of what OS X sees.

Good luck and happy hacking.
