I have a Dual 1.4Ghz G4. I woke up this morning and my mac's screen had fallen asleep like normal. I tried to wake it up and nothing happened. I tried unplugging the keyboard and mouse and plugging them back in, thinking a connection came loose, still no luck waking it up. So I forced it to shutdown and tried restarting. The computer starts to the gray apple screen, where the circle spins for a couple seconds, then kernel panic. So I tried to restart with my OS X retail disc (I bought it for my iBook) holding down the C key, still would kernel panic. Then I tried starting in single user mode to run disk utilties from there. It goes through lots of text, displays the kernel panic image, more text, then says "double panic, were hanging here" I then tried taking the Crucial RAM and Airport Extreme card out to see if those were the problem, still kernel panics. When I restart holding down option, the OS X CD doesn't show up, all I get is my main hard drive as an option. If I select it, it will just kernel panic again. I'm all out of ideas, any help would be appreciated.
