iMac turns on and off immediately. Any ideas?
For some reasons, my iMac G5 20" Model A1076 turns on only for about 30 seconds after the Apple logo appears, then shuts down automatically, wondering what's the problem.
Cette question est-elle utile ?

I hold down the T key, the machines runs for a while, then shows the firewire icon and nothing happen for the next 3-5 mins.

The you can connect it to another computer via firewire and see if there is anything on the hard-drive

Thank you for everyone who have contributed the knowledge and solution to fix my mac!
I am not sure if that's because of the power supply, because I can use the startup disk for as long as i want without any interruption.
I tried to use the startup disk which came together with my mac and try to reinstall the whole OS X, it goes smooth at every stage until where it asked me to choose for the volume destination and maybe there's something stuck, i cannot choose for my hard disk, so i believe there's a problem in my HD.
thank you.

Found out the problem, it may be because my internal HD is dead and I install the only OS X (10.3.9 the only one i got) into an external firewire HD and now it works fine for the last 12HRS.
Probably because the HD is dead, that's why cannot continue the startup or boot up the machine.
