That makes sense of the fact I couldn't localize a spot the smell 
was coming from.  I didn't see smoke, so maybe the thing was just 
getting ready to burn.  Just my luck it won't be obvious on visual inspection.  
 
I've never taken a motherboard out.  Good thing I have usergroup meeting
this Saturday.
