PMDG 737 NGX Causing CTD

Recommended Posts

I am currently experiencing a weird situation whereby on flying in the British Airways livery NGX after about 20 to 40 minutes the sim crashes to my desktop.

 

Now I can ruin the PMDG 737 NGX house version and the PMDG 777 and I do not experience this issue which is the same with my default aircraft.

 

I am using P3D and my OS is Windows 7.

 

Any help would be appreciated please.

Might you be flying the default livery aircraft in different locations than where you'd be flying the BA livery? I ask this because BA usually means LHR, and many people use high resolution scenery, and LHR add-ons tend to be heavy hitters as well. All of that combined will cause a sim crash due to an out of memory error if you do not properly manage your memory use.

 

If you're going to compare liveries, please make sure that you minimize variables: no weather, same route, same type of day, and so on. I do highly doubt this is related to the livery, however.

Hi,

 

I have flown the BA livery in all different locations before with no issues at all.

 

I am not using LHR to fly out of and during the flight and prior to the CDT I have excellent vas about 1.7 left and frame rates in the 50's.

 

I still do not understand why it is this livery aircraft that I have the issue whereby the 737 NGX PMDG aircraft is fine.

 

Further observations would be welcome.

Good question, but the livery has been out for a couple years and there's a lot of users without this complaint so time to do a little digging.  First, what is the nature of the crash? Do you get a message that the sim is shutting down, any other error messages or anything logged in the Event Viewer?  Nice to have additional info to track down what is happening.

Many thanks for your reply.

 

Basically what happens is that the sim screen goes white the sound still carries on in the background.

 

There is no message re fatal error etc- just a white blank screen.

 

The vas is still good considering I am using a PMDG aircraft with excellent frame rates.

 

Further assistance would be appreciated.

Are you dong anything else at the time? Changing between FSX and something else? Using any external programs?

Confirm you have the HIGHMEMFIX=1 setting in your prepar3d.cfg file as recommended in the Introduction.  Is this happening full screen? Are you using ATI or NVidia GPU? Current driver?

 

Years ago in FSX some would get a white screen lockup using light bloom but I haven't seen this problem in awhile, interesting.... also what Kyle said of course.

Hi,

 

Thanks for your reply.

 

I do not have Highmemfix in my cfg as I was under the impression that it was not needed in P3D.

 

This all happens in window mode and I am using a Nvidia GPU and I am using driver number 5382 and have not changed to the latest version as I believe it has caused some issues.

 

Anyway,would welcome further observations.

Michael,

 

Did you note the Blue Screen MS error code in your case? I have had a couple lately with error code 00000124 which is apparently hardware related. Often to do with overheating. There's lots of helpul discussion if you Google on that code. I followed most of it, stripped my machine, cleaned it, reseated all cards and RAM, checked all the fans, updated drivers etc. but too soon to say if this was enough. I didn't reseat the CPU but would do that finally. Even though currently all 4 cores are running comfortably under the high 70's with high loads.

 

Here in Spain the temps have been well into the mid-high 30's C July/Aug so that adds a cooling burden for the PC of course.   

 

Good luck with it.

 

Regards

 

Gareth

Correct and I stand corrected.  Please check your Event Viewer in Windows Computer Management. There should be a critical event logged if P3D, PMDG or any module running at the time is involved in your white screen.

 

Also, check the L-M Prepar3D forum for anyone there that may have run into this. It's the first I've seen reported (assuming you don't get a blue screen) here in a long time... i.e. before Win7.

Thanks for your replies.

 

I do not get a blue screen just a white one.

 

I am only running Active Sky Next as an external programme.

 

This only happens with PMDG 737 NGX-no other aircraft.

As you know, correlation does not mean causation.  I'd like to help but if you do not provide requested information then there's nothing I can do for you.  Please look at the event viewer to see what Windows is reporting. This may provide an important clue.

 

It would be nice to blame the NGX but honestly, there are tens of thousands of this simulation out there and yours is the first reported white screen.  That doesn't mean NGX is not causing your problem but if we are going to figure this out then you need to help.

I have again used the BA livery 737 NGX and after about 1 hour's flying the white screen suddenly appeared  with sim noise still continuing.

 

I went to my Event Viewer and although I am not familiar with this  I saw at the time of the crash this info;

I hope this may show something and would appreciate further assistance.

Now wee are getting someplace. EventID is your graphics driver crashing.  Do you have a current version?  I am not using the latest NVidia to personnally vouch for it but the P3D forum has not reported problems with it.

 

Try updating your graphics driver.

Hi,

 

Thanks for your replies again.

 

I have today flown the PMDG 777 from EGKK to KJFK with no issues at all, 6 hour flight.

 

This problem has something to do with the 737 NGX as this is the only aircraft that crashes to a white screen.

 

I do not believe its p3d nor my hardware.

 

Any further comments would be appreciated.

Faulty logic.  Since your problem is your video driver, it is highly possible that the NGX is in use when you crash but it's not a bug in the NGX. I've done all I can to help you... maybe you should submit a trouble ticket to PMDG Product Support to see if they can isolate your NGX bug.
