This thread relates to a problem I have with my G5 1.8 dual.  The  
problem seems to effect 2.0 dual but I cannot start my computer.  It  
does not chime and repeatedly blinks 3 times.  This is identified on a  
troubleshooting page as bad ram.  However this is the ram that has  
been in use for 5 years.  Reading another discussion the opinion there  
says that the heating and cooling of the motherboard causes a solder  
joint to fail where the DIMM slots connect to the board.

Is there anyone out there who has reasonably priced ideas about  
repair?  My thinking is using a heating process to re-flow the  
solder.  I recall hearing about this but is it at all practical or  
should I sell it for parts and move on?
