Shuttin down & overheating

Hello everyone,

 

Sorry if my explanation are not always clear English, but I am French.

 

Well, my trouble is that since 2 month my Laptop SmartPC 250N XP SP2 is shutting down two or three time a day without any error message & it can be restart without any message too and run after that may be 8 hours without any trouble.

 

Note : No message in the XP event too.

 

I think it could be a cooling problem (CPU overheating), because I notice that the fan is sometime running down before the Computer is shutting down.

 

Could you say me if there is a link for a software that could perform a processor temperature metering & or monitoring.

 

Already done : Anti-Virus, Anti-Spyware, Drivers Update etc...

 

Thanks
