Yes. A replacement motherboard would be my next step too. While bad
capacitors are a fairly common cause, it can be due to other reasons: a
crack in one of the traces or a dry-soldered joint that breaks
electrical connection because of the effects of thermal expansion, or
even the extra vibration when the fans go to full power or even when
there is a lot of disk IO activity.
