Hi guys - advice/suggestions invited ! My SP2 system has recently started to crash on ending a flight or when  exiting FSX (and only at these points - the rest of the time it runs fine). The module most commonly flagged in the Event Log is nvwgf2um.dll, which is puzzling, since (I think) that is a DX10/11 module and I am running DX9.

 

I'm running a GTX580 and driver 306.97, which was installed over a year ago, and has been running fine until this point. The rest of my specs are in my profile.

 

I take regular system images, so I can roll the system back to a point before the crashes started, but I'd rather not do that unless really necessary as there are quite a few changes to be re-installed. And of course if the cause is hardware, then that won't help. Prior to that I will probably try re-building the FSX and re-installing the driver, but all other suggestions gratefully received !

 

 

In Internet Options>Advanced>Accelerated Graphics, make sure the box is unchecked.  If this is okay, then you will need to reinstall your graphic drivers.  I would do the clean install option provided when the Nvidia installation screen opens and you select Advanced Options.

 

Best regards,

Assuming you mean IE Internet Options, then that's certainly something I wouldn't have thought to look at ! But in any event, it is unchecked.

 

Thanks

Well, it took a while, but I found the cause of the problem. And not where I expected.

 

Turns out there was a bug in the aircraft.cfg file for one of my AI aircraft. The line that should have read:

 

atc_parking_types =

 

was mistyped as

 

atc_parking_codes =

 

so in fact the file had two atc_parking_codes lines and no atc_parking_types line.

 

No idea why this should have cause the type of CTD that I was seeing, but it did.

 

What made finding the problem really difficult was that it only occurred when a AI flight plan using this particular a/c was active when I ended the flight I was on. Which  meant that it only happened at certain times of the day ! And I doubt I would ever have found it had I not kept a detailed record of all the changes I made since he last backup and when the error first occurred.

 

In the course of tracking the bug I backed off to a previous level and back again several times. Rebuilding now . . .

Jeez, not sure how you found that, but bravo to you sir.
