So I got the install process to start up so I can instill OS X 10.5. It goes as far as letting me choose my language. Once I choose my language it says "Preparing Installation". At this time it seems like its going to work, but an message comes up that says "Mac OS X cannot be installed on this compute. This software cannot be installed on this computer." Then it gives me two options. One says "OK" the other says "restart". I push okay and it does not continue installing. It just leaves sits there at the opening screen with my options across the top.
I have no idea what to do from here. If someone could help that would be awesome!!! Thank you so much!
