I had never had a freeze until after SU5. Then every week, during our Thursday streams, it would freeze, usually on an approach or just prior . . . I tried the above Xbox Networking thing and it would at least get me back to flying. But it would still occur . . . then I heard about the USB power management info and I gave it a try. Since then, 3 weeks now, have been free of the freezes. I hope it works for you.
