It appears that your laptop doesn't have enough cooling capability and is shutting down to protect itself.
To avoid interruptions, you have to reduce the heat output of your system:
Make sure your laptop's vents and fans are unobstructed and clean.
Limit CPU performance by using the advanced Power Options to cap your "maximum CPU speed" to 50% or so. This will slightly increase load times but shouldn't affect game play.
Enable VSync in-game. This will prevent your system from rendering more frames than your screen can present.
If the above is not enough, use the FPS limiter to cap your frame rate to 30 or so.
In combination with the above, you can lower your resolution to reduce GPU load.
I'm playing in an Intel Core I3 2.53GHz 6GB memory (Windows 7 32 bits
When I play for too long it gets really hot. Sometimes it even shuts down. I already bought 2 fans and put under it.
Can you guys give me any hint to make it not get so hot? Like make the fan work harder?
To avoid interruptions, you have to reduce the heat output of your system:
i think ur laptop got too much dust on itts ventilation., i have a laptop which also overheat due tp long playtime
my suggestion is : open the cover and try to find the heatsink and its fan, tehn brush/blow/suck all teh dust on it with blower or vacuul cleaner
this is only work on long time used laptop
