I have a crash related to the NTDLL on my P3D during my flight from Hong Kong to Amsterdam. I've had this crash before during my flights from Hong Kong to Europe but it was fixed a while ago by using driver booster to update the drivers. It is now happening again and I have:
1. Ensured I have all the latest drivers
2. Reinstalled my display driver
3. Updated my BIOS.
Here is the event viewer log.
Faulting application name: Prepar3D.exe, version: 188.8.131.5275, time stamp
The AVSIM CTD Guide, page 33 (see link to guide in my signature), provides probable fixes for the ntdll.dll and stackhash. It's something you have to investigate. I have had several of them. If I have my system overclocked and getting these faulting modules, I'll go to the optimal default overclock in the BIOS and this fixes it most of the time. Too high or too low CPU voltage and these faulting modules will suddenly appear.
To investigate, I would recommend checking out page 10 of the
