Helping people with computers... one answer at a time.
Games are processor heavy and could be generating a lot of heat. This is the first thing to look at with sudden shut-downs.
Leo, I have a Dell laptop model Inspirion M5010 Core I5. On this laptop, I play MW3 and Battlefield 3. During the game playtime, my laptop suddenly shuts down. What is the reason?
In this excerpt from Answercast #8, I discuss the heat generated by processor-heavy applications (such as games) and look at the option of cooling off the machine.
It's impossible to say exactly what the reason might be. My suspicion is the typical cause of this kind of a shut down: overheating.
Games in particular tend to stress computers quite heavily. They use the processor very heavily and they tend to use the graphics cards fairly heavily. Both of which generate a fair amount of heat when they are used heavily.
The net result is if your computer doesn't have proper ventilation or the fans aren't working or there's too much dust in the way, things can overheat.
When things overheat, what typically happens is the computer simply crashes.
So the very first thing I would look at: [it] would be to clear out your area and make sure that your computer has appropriate ventilation and that it's not overheating.
