Please define "anything too much is done".

Open the case and touch things to feel how hot they are 
(while first making and maintaining contact with metal chassis): 

   The CPU heatsink
   Other big chips such as northbridge or southbridge chips 
      (or their heatsinks)
   memory modules
   electrolytic capacitors

Also, _look_ for bulged electrolytic capacitors.

Look at the heatsinks underneath the fans. Are they clogged with dust? 

Look at all the fans. Do _all_ the fans spin? slow or fast? 
How do the fans sound? smooth or erratic (hoarse)?
