Acer 5738g freeze playing CS and Warcraft

- And yet another example (with a similar solution (to here) offered)

[link] to question - solution below

"I just got a brand new Acer Aspire 5738 with a 2GHz processor, 4GB DDR and a Nvidia GeForce G105M graphics card, when I play a game, my whole computer freezes, usually about 20 mins into gameplay. It doesn't matter if I'm playing something like The Sims 2, World of Warcraft or a simple BigFish game, it just freezes.
Why would this be happening? What can be done to fix it? I have a technician coming out on Thursday, but if I can fix it myself, that would be cool.
Thanks"

"Sounds like a heat problem. Maybe something knocked loose in shipping or delivery. Maybe the heat sink is not making a perfectly flat mate with the fan. If the graphics card/chip has a fan, maybe it's not spinning or the GPU heatsink isn't properly mated."
