Hi,
I restored some months ago my PowerMac G4, but now a new problem showed up: "bus error". At every boot this error shows up. I reinstalled the OS so many times that I lost the count. Usually when I reinstall the OS, this error shows up after 5 powers off or sometimes I install the OS, the Finder crashes continuously with a massage "Finder quitted unexpectedly - It's better to restart the machine", I restart the Mac and "bus error" shows up. Sometimes the error comes up also at a CD boot attempt and always sometimes the "bus error" disappears after opening the case of the PowerMac and connect-disconnect cables. Does someone of you have the same issue?
