I am not sure of the exact model but it is one of the first generation intel MacBooks, circa 2006. It worked perfectly up till last week. When I try to boot normally from the internal hard drive, it will not go past the white screen with apple logo and spinning wheel. If I try to boot from the original installer DVD it ejects after about 30 seconds. I tried connecting to an external HD via firewire and starting up with the option key held down but it only sees the internal HD. I tried zapping PRAM, taking battery out, holding power key. Nothing helps. I already have a new machine but I was hoping to give this one to my young niece. Is it worth fooling with anymore or should I just give up? Is there somewhere I can donate it to for parts? Thanks in advance for any advice.
