ok so I finally have the Alienware reformatting again. so after getting it to the desktop and every thing I will try installing FSX the way I did on the Dell computer. I will get every thing cleaned up including the registry and getting all the windows updates and install the stuff I need for FSX before trying to install it and see if it works then. if not I know a computer that will be looking for a new home. cause I have the Dell and the Alienware set up side by side so I can fly on one and work on the other. im hoping it works if not I'm out 2,450 bucks :(
