Macbook shuts down when playing games

[FB2011]

Hello, can someone please suggest what i could do.... My Macbook shuts down when i play games on the internet, even when it is connected to power. It gets very hot to the, the fan seems to run constantly and then it just shuts down......I've been playing these games for 3 years and never had this problem..... Thanks for any suggestions

That's your MacBook making a last-ditch effort to stay cool - by shutting down. If it is three years old now, pop the top off it, grab a can of compressed air, and go to town getting rid of accumulated dust. If that doesn't instantly solve your problem (which it should), or you just want to be extremely nice to your MacBook, you might want to go ahead and replace the three-year-old thermal paste on it while you're in there.
