Is there any error message ?

no! without reason shutdown! how i can sure it's for heat? or fan speed ?

How old is the laptop ? How long is it on before it stops ?

If you want to check the temps, download CPUID HWMonitor and see if it gets too hot before it shuts down.
It will show the fan speeds also.

Download here: HWMonitor CPUID - System & hardware benchmark, monitoring, reporting

I checked with SpeedFan. The Result is:

HD1 : 33C
Temp1 : 42C
Core 0 : 37C
Core 1: 36C

How about the other two questions ?

How hot does it get when it stops ?

Yes. The Fan is working very bad! and in High use laptop is shut down! It's hardware problem and i should change fan? or i can use a coolfan for it?

I touch it with my hands and work very bad

When was the last time it was cleaned out ?
Can you look into the air vents or the fan vent with a flashlight to see if there is a lot of dust in it ?
