Hello, Some troubleshooting on an earlier thread a week ago made me think that the main (upper) processor on my G5 has died. I would like to switch it with the lower. Does anyone have reccomended instructions for doing this? A google search does not really come up with anything for my exact model. I've also tried mroogle. I have the 1.8 Dual Processor Model with 4 RAM slots if that helps. Thank you!
