First off, I wanted to say hello to everyone. I have used this forum to find answers to many questions I have with my flight simming. However, I have encountered a problem which I can find zero information about. I have searched the forums and the net for hours and have found nothing.

 

Recently FSX has started to randomly freeze during flights. It also now freezes and crashes at exit 100% of the time. Normally a crash at exit would not bother me but I am certain these two problems are linked.

 

Every time the freezes/crashes occur are when I am usung the PMDG 737 NGX. In my search to find the problem this is what I have come up with.

 

Checking the DXDIAG it reports no problems found.

 

Checking the event manager here are the results:

I know some will say that FSX needs to be installed in C:\ but as I stated before, this problem just recently started. No problems beforehand. Something is causing a d3d9.dll error and I am going crazy trying to figure it out. I have never installed the other programs that would put the hacked d3d9.dll into the fsx directory. Just to be sure I checked the fsx directory and did not find a d3d9.dll file anywhere. It only exists in the system files.

 

Since this was a dll problem I then went into my dll.xml file for fsx and removed it from the folder. Started up and no problems. everything ran fine. So now I think I am narrowing the problem down. Systematically started turning off components on the dll.xml file and tried to recreate the problem. Problem still exists until I disable PMDG.

    <DllStartName>module_init</DllStartName>
    <DllStopName>module_deinit</DllStopName>
  </Launch.Addon>

 

When I change this to <Disabled>True</Disabled> the problem goes away.

At a complete loss I decided to do a repair install on the PMDG 737 to see if maybe a file had been corrupted. Success! Everything seemed to be buttery smooth afterwards! That is until the next day. The problem came back and disabling the pmdg seemed to be the only fix.

 

I am at a complete loss with this issue and it is driving me crazy. 

 

I am running Windows 10 Home

Intel Core i5-4590

8 GB Ram

Nvidia Geforce 750 with current drivers.

 

FWIW Windows did do an automatic update and changed my OS from Windows 10 Home to Windows 10 Home Anniversary. This was done while I was out of town for work and the option to rollback was changed from 30 days to 10 days and now I am stuck with this OS.

 

If anyone could help me track down this problem I would be very appreciative. Also, if there is any other information that I have left out please let me know and I will get that information posted ASAP.

 

Thank You,

 

Richard

 

 

Richard, full names in the PMDG forums please. Note the pinned forum rules for clarification.

 

Freezes. You didn't say how long these events last because there's a difference between a millisecond freeze and a 6 minute freeze; either of which could be called a freeze.

 

I can't help with the crash on exit. I had a FSX configuration that always crashed on exit and I never figured it out. I just moved on to my next computer build. However, freezes is something you can do something about but it depends on whether it is a long frame or an appHang.
