747-8 CTD (again)

Recommended Posts

Posted (edited)

Thought I had the issue resolved but while I was playing around with the EFB during a flight I got another CTD. Same error codes as before. Here's the log from the event viewer below.

I was told by PMDG support that the error code CLR20r3 is related to overclocking issues, and sometimes corrupt or outdated drivers. I only have factory overclocking on my GPU so I opted to reinstall my GPU driver and that seemed to do the trick for awhile. However it appears that something else is going on here. I already tried to do a clean reinstall of the driver again but that doesn't appear to remedy the problem anymore. Maybe someone here can offer some insight that PMDG support can't.

Faulting Application Path:    E:\Program Files\Lockheed Martin\Prepar3D V4\Prepar3D.exe

Same answer as before.

The same crash dump is pointing to the same issue. Graphics card/driver issue. Right in the crash dump.

Try cleaning out all driver files and folders.  Get DDU (display driver uninstaller) (free) and run it with windows in safe mode.  Safe mode is required to completely  clean out old files.  Then restart windows and download current or known good driver and install it.  Hope this helps. It has help me on occasion but isn't always the solution.

I myself use the ccleaner to clean out any leftovers before i install the new drivers.
