I am having trouble with a powermac 1.6 I picked up. I have leopard 10.5.3 and all the updates to all applications. I am importing CD's into Itunes in Apple Lossless format. Intermittently the entire computer will completely freeze and all the fans ramp up until they are at full throttle.No Kernel Panic just frozen and fans on... The weird part is that it is usually half way through the last song of the CD. This is true 9 times out of 10. It doesn't matter which CD or how many songs are on it will be the last song. Dont get me wrong most Cd's import fine, all the way through, but some lock up. Then I will just select to import that one song that was missed... after I reboot... and I will move on to the next CD. Other than this the computer runs great. Its seems way to specific to be a hardware problem sounds like software... any suggestions? Note all Cd's are pristine... hardware monitor IStat indicates normal CPU temp.
