Games freeze on brand new laptop

Hi, here's my problem:
I bought a brand new Asus x52j I3 2.4ghz, 3gb ram and Ati Mobility radeon hd5470 512mb win7 home premium (Legal). After 2 days I tried to play some games and ALL of them have the same issue - they freeze... I tried Fallout 3, Mass Effect (1 and 2) and Deus Ex: Human Revolution and ALL of these freeze a lot (Mass Effect 2 even doesn't go past the first cinematic and Fallout3 usually doesn't even load up the menu 'till it freeze) don't know what's the problem... my drivers are updated (ATI CCC doesn't even work somehow) Any ideas what might cause this problem ?
 Don't think overheat is possible because Deus Ex performs pretty good with serious heatwaves coming out of my heatsink and Fallout 3 with Mass Effect 2 freeze within 1-10 minutes (which is probably not enough to heat out my hardware)
 Can't even describe how frustrating it is 
Please answer ASAP

Sounds like a heat problem to be honest. It doesn't take long for heat to shut a system down. A failed CPU fan, improperly installed heatsink, and other things can cause a computer to overheat in about 15 seconds in some cases.

I worked on a computer the other day that had this problem. It would run fine if just in Windows, but it would crash if pushed slightly (even playing a YouTube video was too much). They played World of Warcraft, and within seconds of the game starting and they were at the login screen, it would freeze. Turns out their CPU cooler had come unplugged. The massive heat sink it had was enough to keep it cool enough for basic things, but the moment it was pushed, it would overheat without the fan inside to circulate the air.

Try downloading Speedfan and see what your temperatures are like:

Yup, it should be overheating which causes the problem.
You can try to get a notebook cooling base to see If the problem persists. They look like this:


Otherwise, the best way to deal with the problem is to talk directly to the supplier.

Thanks - it WAS an overheat problem. I downloaded 'SpeedFan' and even when I logged in to my computer it showed that the heat was already climbing over normal. Turned on Auto Fan Speed and Mass Effect 2 performed A LOT better - I was able to play it for like an hour or so until it froze again. Parts were almost over 60C and fan was working at 3300rpm (2100 is by default). Would it help if I got a better cooler fan installed ? I think the cooling pad would be too expensive for me - paid everything I had for the laptop 

Edit: Just checked the cooling pads - they are not so expensive, but do they actually work effectively ?

Maybe you need to understand that laptops are not exactly meant for gaming !!

Yeas, they are not very expensive. I would suggest buying a cooling base which has at least two fans(or more) on it. Cooling fans can help decreasing the laptop's temperature a lot.

I raised my laptop from my desk and it already does wonders
I think I'll DIY a cooling pad myself airflow should be pointer downwards ? 

Yes, airflow should be oriented to pull the heat away from the laptop.

Something like this would work well... I have a similar one for my laptop (17" screen):

Guys you should acknowledge that the laptops are not for playing games you should play through your pc or
on xbox.

You're not the first person who says that and I DO know they are weak for gaming but overheating without any real performence requirement (loading screen, main menu, intro video) ? That's a bit screwed up ... By the way tried to watch a movie last week... Guess what... Yup - it froze, although the salesmen said I could watch HD movies on that laptop. Bah! I guess I need to take it to warranty service and ask what the *censored* is going on ...

Laptops overheat. Documented fact.

They can do if they are not used properly.

Then tell this guy he has wasted his time. Just  use the laptop properly. Never turn it on.

Come on! be sensible. Plenty of people (including me) have laptops that don't overheat, at least partly because they don't use them on carpets, quilts, blankets etc, they keep dust out of the fan, inlet & exhaust ports, and they don't run them as if they were a desktop.

Any computer, laptop or desktop, will overheat if not maintained properly or used in a way it isn't designed. I've never had a problem with my laptop overheating, but I keep the vents clean and make sure the vents are never blocked by something. I don't use a cooling pad for it, even when I've played games on it, because it never got hot enough to need it. Saying "laptops overheat" is an incorrect generalization.
