I am able to reproduce this by getting in any heli or jet and flying round and eventually usually between 5 - 30 mintues it will crash usually crash's if i get shot by a missile or crash into the ground it will freeze and i have to close with task manager, im sure you can understand how frustrating this is when it happens every single night and it has worked before perfectly with out and ssd however i have no idea how the ssd would only cause it to crash when flying.
