I formatted my computer again, and it only has Windows 7, FSX and 737NGX. No more addon to avoid interference. The problem continues. In the early afternoon, unhappy with all this, and 737NGX FSX installed on the computer from my son, who never had FSX installed. It's another computer, another motherboard, another video card, other memories, no relation to my i7. And my son runs everything perfectly all he wants and likes. Well, I installed everything and did the test. Result: The SAME THING HAPPENS, THE SAME WAY LOCK, GIVE THE SAME MESSAGE FLIGHT SIMULATOR NOT RESPONDING AND LOCK, paralyzing the functioning of 737NGX PMDG and FSX. I uninstalled FSUIPC and everything is working again perfectly. Today completes 1 month'm in this fight to find out, because this problem happens.
I await guidance!
