Hey geezer,
I did everything I can think of these last few days, including your tips, I even updated to the latest BIOS, but nothing helps. I did some research, even on here forums, and looks like the Brisbane core thermal detection diode is broken.
Awwww man, I'm so bumed out...

....how can they screw up something as a diode?!?
Can anybody tell me is this the thing with all Brisbanes or just the early ones?
