Hi-I am back to simming after a few years. I have purchased a new high end machine and have installed prepar3d and FSX. Repeatedly after a two minutes or so after take off my system just shuts down. This has occurred whilst flying both the Aerosoft A319 and also on one of the default twin engine prop aircraft. It seems to occur soon after engaging the Autopilot. This does not occur whilst flying a default aircraft in FSX.
Does anyone have any clues?
Thanks
