I installed the PMDG NGX on Windows 8, but there is continuomente, even in cold and dark, a continuous sound and strong air conditioning. I tried reinstalling the program but I have not solved. Sorry for my english.

1. Are the engines off for sure?

 

2. Are the pack switches ON or on AUTO?

 

3. Do you have an external air cart connected? (any readings on the bleed duct pressure gauge?).

 

4. Is this (FSX and/or PMDG 737NGX) a new installation?

Turn the pack switches OFF and see if that makes the noise stop (if you have not done that yet).

 

And you are verifying that the bleed air duct pressure gauge is reading 0 correct?
