Laptop's specifications:

cpu: intel i3 380m
gpu: optimus; intel hd, gt 540m
ram: 4gb

MY problem:
I just installed a new awesome game which is "Tomb Raider".
I run it in normal settings then benchmark it. 1280 x 720

lowest: 1.8
highest: 42
average: 38.2

it's fine for me but then, I tried to create a new game....it runs fine until tomb raider has been punch out O_O....then my pc automatically turns off....I tried to play it again four more times but I'm getting tired of seeing lara being puched....then i suspected that their is some problem with my CPU....

i run the task manager while playing Tomb Raider....I saw some strange CPU usage....it runs an average of 78% and sometimes it goes up to 98% and also 100%....then blank....O_O....

I've tried it in the lowest settings and in 800 x 600 resolution....it runs good until 25 mins later....blank...Shutsdown again automatically.

Please tell me what is the problem and what is also the solution.

do i need to buy a new CPU?
or should I just clean the heatsink?. the heatsink where never been opened for centuries :D
should I also apply a thermal paste?
and how should i know if my heatsink or fan inside the laptop are still ok?

sorry for too much questions....I really need them. :D

also....how can I monitor my laptop component's temperatures?

No need for new cpu.just clean up the fan and apply new thermal paste.since u havent opened it for ages dust might be clogging the fan.make a habit of cleaning ur laptop internal at least every 5-6 month.use coretemp,realtemp or hwinfo for temp monitoring.just google them.they are free for donwload.
