[G5] G5 June 2004 dual 2.0 Processor problem

[Eric Volker]

One possible problem may be the temperature sensors and/or  
overheating. When you lock up, are you running intensive tasks, or  
does it just happen at random? You've obviously opened it up; is there  
a lot of dust on the inside of the G5 or in the power supply? Have you  
looked at your system logs to see if there might be a clue in there?  
I'd also try running a temperature monitoring program and see if  
temperatures are getting unusually high in the processors. Just a few  
suggestions...
