    Removing the CPU Assembly

    Hi...just finished this process myself. I have a late 2005 2.5 GHz Quad G5 with 1 pump and it took a bit to figure it out. If you look a bit, you will find a manual on the web for free.

    but, the answer to your dilema may be that you need to remove 6 main screws that protrude down through the aluminum base plate, 4 screws that attach the power wires to the CPU boards, 4 rounded head hex screws that the manual says to "loosen" and 4 tall hex bolts next to the radiator. Completely unthread them (not just loosen) The manual will make things clear to you. Good Luck!

    You'll have to post the whole kernel panic so that we can best determine what's causing it. Even a clear picture of it would work.

    It appears that it could be a problem with a PCI-e card. Try removing all but the video card and try again.
