Game keeps freezing after a few minutes of gameplay

Hi guys.. My ARMA II keeps freezing after a few minutes of gameplay and I gave up trying to solve the problem .. Sometimes it freezes and I can still hear the background noise, sometimes it freezes and there are weird greenish cubes that appear on the screen ... I tried OA Demo and the same thing happens ... It freezes and I have to reboot my computer as the only way to get out of there.

Please help me, I'm seriously getting pissed off with this, how can Bohemia release such a bug filled game? I've spent way too much money.

My specs

Quad Core 2.4Ghz

2GB Ram

Nvidia 8800GT

need some help in here!!!

Artifacts on the screen sometimes means a heat issue.

I have a similar computer with an 8800 GT and I use Rivatuner to keep the fan at 100%. Otherwise it gets very hot with certain games.

Is there any other information you can give us? Video driver version?

what psu do you have. i used to have a enermax 600 watt,i used to freeze all the time in arma, since i bought a new psu i aint had a single freeze, all my other components were good and up to date was just the psu. but not saying its your psu it was just my issue why i was crashing. i play a whole host of games, bf series,cod series,racing games,and the only game to freeze was arma. guess arma uses a lot of power to run.

Same issue here. Game freezes randomly, usually with black screen, locking up PC.

Specs:

AMD PhenomII X3 720 2.8Ghz

ATI Radeon HD 5800 series (latest driver)

6GB RAM

Vista 32-bit SP2

May be entirely different cause to OP, but just to flag that this problem is not isolated.

Edit: Having run the game in windowed mode to check machine temps, the game ran without a hitch. Not sure why this would be the case, but it may be something to try for some who are experiencing lock-up.
