System Shuts Down During Games

Greetings - A number or thing could be owing to this - here is a list of possilities -

A: You bought or built a computer with an out of date Video Card.
B: You didn't install your video card driver, so the computer is referring to an onboard driver. That would make your computer crash for sure!
C: you built the computer yourself and forgot to put in a heatsink, so everything is melting.
D: You don't have enough RAM available for the game to work. You may have enough ram on your computer, but you may not have enough FREE when running your battlefield game. Shutdown unneeded processes and applications. WARNING: Only shutdown processes if you understand what each one does and the consequences of shutting down the wrong process like explorer.exe which some people confuse with iexplorer.exe. There is a huge difference
E: You have a single core processor which isn't fast enough to run your game.
F: You have an intermittent power supply.
G: You have or had magnets near your computer.
H: A wormhole formed inside of your computer and sucked your video card into another time period.
I: Battlefield doesn't work with your video card. This is a rare issue now a days, but it can still happen.
I hope this was helpful; well excluding

Well, as you said it yourself, your laptop is overheating and it is only logical that it shuts down during games like PES 12, that use a lot of the laptop resources. The shut down probably occurs as a way of preventing your motherboard/cpu from burning out. Also, if your fan is really loud, it is either very dusty, or it's just near its end. Anyway, you should take the laptop to a service and have it examined. Meanwhile, don't play any games or start any applications that are resource-heavy.
