Hi guys, Could someone please help me? I have just bought a new iMac 24" 2.8. It had a drop in leopard DVD so I have up dated. Set up time machine, set up mail, tranfered all contacts, photos, music, doc etc, and have installed logic 8. I did a software update and it asked me to restart my computer so i did. the computer just hung (it just showed the wall paper, you could move the mouse but couldn't do anyting else so I turned it off by holding down the power button. When i turned the computer on it went into setup assistant. I went through the setup again and then it went back to the first page of the setup. I had to power down again. Now when i boot, finder show setup assistant in the menu bar but you cant do anything! So i power down again (press and hold the button). and it boots back up to setup assistant again but will not respond to anything. Any ideas?
