Computer crashes after 3-5 minutes

[Keifrador 1]

Hello,

I recently purchased ARMA II: OA on Steam to play DayZ. I have downloaded the six launcher and successfully update it each time I attempt to play the game. On entry into the game server after 2-5 minutes of roaming around my screen literally goes into standby mode and my computer becomes unusable, the only thing I can do is shut it down. I've tried everything, may I please receive some assistance?

Specs:

Windows 7 Home Preimum 64-bit

Intel Core i7 CPU 960 @3.2ghz

12GB of DDR3 Ram

Amd Radeon HD 6800 1GB Graphics card

Check your temps.

All new PC's shut themselves down if the temps get too high.

Also, if it's just your screen going dark, I'd check the GPU as the source of the problems (temps, re-install drivers and, if you can, switch a GPU to a temporary one, like from a friend).

SOLVED. AN EASY SOLVE TO MANY PEOPLES PROBLEMS. Stop your graphics card from Overclocking automatically and turn your games settings from 'VERY HIGH' to 'Medium' (THE GAME IS EXTREMELY DEMANDING) I did this and now my GPU stays at 52C which allows me to play the game. Thanks to KRTSHV for suggesting to look into my GPU.
