ok then i blame the BGA , the graphics, flood the bga with flux, and re flow it… i bet there is a little piece of solder in the array causing a short.

its pretty much the only thing with those that goes bad.

that is the one thing that really gets me with apple stuff… the MBP/iMac g5 and intel/Powermac G5, etc They let this stuff get way too hot!

all because they don't want to hear a little fan noise!
