okay guys, i really need your help on this one. I've got a dual 2.0GHZ G5 (the original one from 2003), apple care just ran out on it and its not starting up. Here's whats going on. It will turn on, the apple logo apears, the blue progress bar shows up, it goes all the way thru then it goes to the blue aqua screen and then a second later the cursor vanishes. The CPU is crunching away and after 10-20 seconds the back spinny shut down circle pops up and then it goes away and the monitor just keeps pulsating with the blue aqua screen and no mouse cursor. I've re-installed OSX tiger (with it set to archive). The same issue happens, blue aqua screen. I've also ran disk utities and all the hard drives had no errors or issues with them. Has anyone had this issue before and/or have a solution for it. Thank you so much.
