Q: Powermac g5 won't, do anything.

Here is the skinny....

 

A week or so ago I was listening to iTunes and cleaning up a bit. All of a sudden the screen went black and the music stopped. I sut the computer down, forcpushy holding the power button in. And I rebooted it after a cool down to see if it was something other than what normally happens to these. It restarted just fine and ran for about 10-15 min and did the same thing. Now knowing that this thing has a LCS (Liquid Cooling System) in it i figured this is what happened, it leaked. Well I took the computer and placed it on its side, unplugged it, and pulled the side cover off to allow it to cool down.

 

A few days went by and I finally had some time to dig into it. I removed the G5 cover and i emmideatly saw the problem. My coolant leaked out. Being a mechanic I busted out my tools and pulled the LCS out. I removed the processors and inspected them for any water damage, to my glee, none. Next was the coling system it's self. The parts that leaked where the bottom of the water pump and the sockets that sit on top of the processors. I removed all the parts that leaked and repaired them, well actually what I did was added a few more things to the system and put a rest or on top of the computer as well as used a non-conductive coolant.

 

Today I finally had toe time to resemble my G5 put everything back together and went to fire it up, nothing. And I mean nothing. All I get out of the comuter is the clicking noise from plugging it in.  From what I read this a sign of a good power supply. I have tried everything from replacing the battery to hitting the PSU button but the fact remains that nothing happens when I hit the power button on the front of the computer.

 

If anyone has any thoughts or ideas on how to get this thing back on the road it would be greatly appreciated. As well as any threads that I may have over looked on a possible fix.
