I have connect my Throttle Quadrant (GOFLIGHT GF-TQ6) by FSUIPC ...!? In other Flights with this PMDG 737 I never had BLACK SCREEN ... in my FSX.cfg I have follow all tips of PMDG .......is it possible a error in flight plan? can you help me? Lucio

Look up dusapearing texture fix I think that your errors is realted to the way windows 7 handles sound.

I too have had the suspisionthat my system cannot handle sound in win7 32 FSX Accel. Many a time when on approach,be it manual or ILS I get black screen and after a while CTD, Most annoying; Maybe my ystem is not up to specs?
