PC crashing when running ArmA

[CJoriginal 10]

Hey guys,

I don't know whats happened to it, but my PC keeps crashing when i try to run ArmA. It runs ArmA 2 perfectly and about 2 months ago it ran ArmA 1 perfectly too. It loads ArmA up fine but after maybe 1 - 2 minutes, my screen goes black with a message saying 'No signal found', which then leaves my computer frozen. I have tried reinstalling the game, and reinstalling my drivers however it still keeps crashing my PC. I dont know whats happened but if anyone can offer suggestions on how to fix this it will be brilliant.

My computer specs are:

Intel® Core2 Quad CPU Q8200 @ 2.33GHz (4 CPUs), ~2.3GHz

4GB Ram

DirectX 10

NVIDIA GeForce 9600 GS

The current versions of ArmA 1 i run are Queen's Gambit on version 1.14 and i also use the beta patch version 1.16, however neither of these patches work anymore.

If someone can help me, i will be very happy. Thanks :)

Make sure your video card's cooling fan is still functioning. This sounds like a card heat problem.
