2011 15" MacBook Pro Freezing when Gaming?

I think that Snow Leopard just got updated... to 10.6.7 and they said the beta or the actual release fixed 25,000 minor flaws and security flaws. If not, since the computer is 2011, that means you bought it this year, you still have a warranty. Apple has the BEST, and also rated, and proven the best customer support in the world, so you won't have any trouble if you call or take it to the Apple Store(: Good Luck!!(:
