Acer 4402 Problem in Games

Hi all! First of all sorry for my english ...

I've got a problem in games with my acer 4402Lmi.
When I play games my notebook in few minutes hand-up. I think it is caused of overheating but i read forum and some people have similar problem with overheating but they say nothing regarding system's hand-up.
I've installed latest 6.1 catalyst and when game hangs up system just staying a few seconds and then game restored but sometimes system crashes.

But I'me curios that sometimes games crashes just after 3-4 minutes of playing (even when the system was not working before some hours and absolutely not hot) and sometimes the same game crashed after more prolonged playtime i dunno maybe 30 -40 mins with the same game in same situation...

I'm absolutely sure that this is a problem with video card. And one more interesting moment - When with new catalyst drivers while playing game system hang-ups for 2-3 times and then restored and then finally game crashes, if I try run any direct3d application it will not run and I run DXDIAG and in Display - I've found that there is no Direct3d support on my videocard !!! when system restarted everything goes back - games runs and direct3d becomes active...


I've purchased notebook just a few days so I think radiator and vents are clean...

Will try to install Omega drivers but i don't think it will help...

verheat: Maybe somebody can advise something ... Maybe is not a problem of overheating ? And if it is overheating are any availability to finally burn the videocard if playing a lot of games ?
