i recently got a macbook 1,1, i installed os x snow leopard on it, for the first couple weeks everything worked great, but now randomly the keyboard and trackpad stop working, then they randomly start working again, it didnt start doing this till after i took the top case off to look inside at something....is this a software issue or could the ribbon cable be ripped in a spot? when the keyboard and trackpad stop working the power button still works, usually when this happens i reboot it and everything works again, please help
