I really need help getting my PowerMac G4 back on. I was having problem with it and I decided to re-install the software but mistakely I used the software re-install disk and wiped out the whole hardrive so I it doesnt have OS on it. When I turn the MAC on, it only says please restart your computer. I am not sure how to get it back on. And unfortunately I dont have the install discs for the computer. If somecan point me in the right direction or tell me where can I get the cd to install the OS. I'd really appreciate it. Thank you for all your help.
