Hi,
I have an iMac 2 GHz PowerPC G5
it will just shut off I get the black screen then I here the start up chime and it comes back up.
I took it apart and blew out all of the dust to see if it maybe this would help.
I downloaded a program called Temperature Monitor to see if it is getting to hot and just powering down then rebooting itself.
Does anyone have any suggestions on how to fix this problem!
Thanks
Carolyn
