         All right! Thinking again, the crahses never occur when the window 
of the room is wide open, during the day. It happens mostly in the evenings 
(or nights) when our system engineer has left home.
         The system is a tower on the floor with the case open, and, for 
the time beeing, I will search a fan to blow on it. Oh yes, and the system 
was crashing more often when it ran with the case closed.
         I have allready asked for an air conditionning directly in the 
room and your opinion will surely help me.

         Thank you very much, again.

Adrian
