I read a couple articles on other websites and this is what I found:
Action: I held down the space bar, at the same time I pushed the power button, until the Apple logo appears
Outcome: skipped login screen to desktop. works fine for a little while then freezes.
Action: Hold power button until it's forced to shut down. Rest for 5 seconds. Push power button. Hold down shift key when welcome sound comes. Let go when Apple logo appears.
Outcome: Login screen appears and works fine then eventually freezes and I have to repeat safe boot (only way to turn on computer and avoid blackout screen)
Now that the computer is on and working, I connected it to the internet but it did not have an IP address so I typed in a random IP that I found online. I don't think the IP address is working properly though. Does anyone know how I can set up my own IP and subnet mask?
Also, I found out that the it is an iMac G5 so I think it was discontinued in 2006?
Thanks again for all your help! I'm new to all of this and still learning what all this IP Subnet Mask etc. is.
