OK I am at my wits end. My trusty Mac is now dropping the Internet connection. I have checked the lines, router, cable modem. I have hooked my Dell laptop up to the same router and lines and had no problems using the Internet. Also, I even took the Mac to a friends house and it even did it there. I even formatted the computer and installed Panther thinking it was Tiger and it was not. In addition, the fan will sometimes make a strange sound. Am I slowly experiencing hardware failure? It is a Mac G4 Dual 867 Mhz, 60GB HD, 1GB of RAM, Superdrive, has all software updates and is spotless on the inside. Any help is greatly appreciated.
