Hello, i am having a complete computer reboot crash while taking off on MSFX. I can fly all day with nominal video settings when i start in the air, however when i start a mission on the ground (even on the lowest possible settings), it will load fine and i can sit on the runway with no problem, but almost instantaneously after i start throttling for take off the computer reboots. This happens reguardless if i am using max throttle or incremental throttleing, when im using my joystick, my yoke and throttle, or my keyboard. i do not get any error any stuttering, i have a solid framerate. it only happens on the runway 0-2 seconds after hitting the throttle. i am running windows xp 32bit, i thought at first it was possible a memory problem so i bought another gig of ram and it still occurs. video card is an ati 5330. any help would be appreciated.
