The mother board and the cooling system has been replaced by Dell and since then, the temperature of the CPU remains a lot lower. No more slow downs, no more sudden-death. Things look good now and I am guessing that the few kernel crashes that happened were the results of the CPU mis- behaving under high temperature.
