my computer just gets halted , in the middle of my working in my laptop, and it continues for couple of time , even if i restart it forcefully by pressing power on button, when i once restart it, a message was displayed at the very start , about some high temperature , what might be the problem with my laptop ?

Can you hear the fans on high, or are they not on, or are they normal? If there on high, see if replacing the thermal paste will fix it. If they are not on, replace the fan. If they are normal, I honestly have no clue.

I agree with @gigabit87898 . It seems to be a problem related to cooling fan or thermal paste. At the same time I would also recommend you to have your laptop serviced for dust etc. Then you might expect improvement in your laptop’s performance.
