I get random Whitescreens with an Arma3 crashed message soon after.

Sometimes i can play for 1-2 hours without a problem and then it crashes, other times it happens after 10 Minutes.

The crashes occur faster when i play Altis Life, instead of Wasteland. But even the Singleplayercampaign, can't be played for more then 2-hours before it crashes.

It happens when i walk as a Footsoldier, or drive in a car, of fly around. {F23530}
