Travel mate 8210 heating and there seem to be noise comming from the fan

When the CPUoverheats it goes into thermal shutdown and will not boot up again until theCPU has cooled down.
The heat sink may be clogged with dust, which causes the CPU to overheat byreducing air circulation through the heat sink. If you are notusing your laptop on a flat surface, it may be obstructing the cooling vents onthe bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem
