My laptop scared me to death while running a game !! please HELP!!?

Question

Hi everyone
I have a Lenovo G580 laptop with a 4GB ram and an Intel Core i3-3120M procersor with Windows 7 Ultimate 64-bit.
And a NVIDIA GE-FORCE Graphic card with a 1696 MB of memory.
I played Need for Speed Rivals on my laptop and the game ran without any problems (that was a while ago) but since then, a lot of softwares were installed into my laptop.
But today I installed Metal Gear Rising - Revengeance, and once I entered the ""Press Any Key"" screen, I opened Options and set the Graphic's quality to "Medium" and the rest of the graphics options were set to medium too
Then I started to play and it ran brilliantly (for like 5 mins) in that period I didn't notice any lagging or cutting.
But suddenly, the laptop's screen went black (it shut down on it's own!!) I didn't see any warnings before that shut down.
I'm really scared that if I try to run that game again, something awful might happen to my laptop, although before I ran the game I set the power option (in the battery's options) to ""Lenovo Dynamic Graphics"" cuz I thought doing that might make the laptop run the game using the graphic's card full capability.
should I be worried? or is there some sort of heavy task that could've caused that involuntary shut down?
And I don't think it overheated cuz its placed on top of a cooling fan.
Thanks in advance.

hi shehabo,
From this this benchmark result, your right, the Lenovo Dynamic Graphics power setting gives the CPU/GPU more juice to complete tasks in less time (kinda like an overclock). If your machine shuts down in this power setting (while battery or AC power), it's possible that the hardware throttled or used its overheat protection by shutting down the machine to prevent further damage.
If you have the G580 with an Nvidia GT635M, your machine may not be enough to run Metal Gear Rising: Revengeance as it doesn't meet the minimum system requirements.
Metal Gear Rising: Revengeance - System Requirements
In this case, the game may not run properly or stall while loading or playing (in your case, the machine tried to run the game but may have reached its limits when it got exhausted).
As for the Need for Speed Rivals, your system meets the minimum system requirements, thus, you encountered no problems running the game.

Thank you for replying
As much as for Metal Gear Rising, I didn't notice any stalling or any cutting while loading and while playing. that benig said, my laptop should run the game perfectly normal. I had the same problem with Need for Speed Rivals on my PC, it kept overheating after like 5 or 15 mins of playing but the laptop didn't.
But as for the Graphic card,
when I open the Advanced Settings in the screen reslotion window it says: Intel(R) HD Graphics 4000, but my laptop has the green "NVIDIA GEFORCE" sticker under the keyboard's numbers keys (I though that ment it has a powerful graphic card)
