Thanks for the advice, but unit runs all the time on high speed including on booting an external system and fails to boot on asd 3S108 diagnostic. Only on AST/MRI gives me that error. It could be a bad CPU or MLB?
Check the article below for instructions to reset the SMC and PRAM.

3S108 could mean a sensor problem
