Hoping someone can help me with a problem I am having with FSX. After flying a few minutes, my LCD goes black and purple and black vertical lines appear on the monitor shortly after. It seems that this problem first occured when I added a text line (forgot what it is) as recommended by Nick in this forum to my command prompt in Vista. To change Vista back to its stock configuration, Nick recommends adding a different line to the command prompt. Unfortunately no luck. Will a re-installation of FSX plus Acceleration fix this problem?
