Hi there, I have the same issue and I am now attempting the solution given by fregac. I would like to be sure I am not doing foolish things so I post here before heating anything: I don't understand point 2: «2: Remove the two small heatsink assemblies from the front and back of the board. They are held in by four spring-loaded plastic clips which can be released with a pair of needle nose pliers. Be careful! If you break the clips replacements are impossible to find, and those heatsinks are necessary.» I don't see these heatsink assemblies. I gather that one has to unscrew the large ventirad copper radiator where the G5 letters are printed, held by screws mounted on springs. It was very dusty. Then I only see a sticky pink patch on the nVIDIA GForce chip. I gather this is the GPU I have to heat, right? I don't have to mess with the two other large chips, right? There are two plastic foils on the mother board, one close to the GPU, the other around the CPU and far away so I won't mess with it. I understand...
