Constant Crashes out of nowhere

Hi All,

I have run FSX on this machine for over a year, and never had any problems with freezing or crashing. I'm beside myself with frustration, and beg you all for some guidance! Thank you in advance.

In the past 2 weeks, I have done the following,

- Purchased and installed a new video card (XFX Radeon R7 360) and applicable drivers. Used for 2 days with no freezing happening.

The 3rd day, I:

- Installed a 3rd party replacement of default some trees, textures: http://flyawaysimulation.com/downloads/files/1373/fsx-modified-terrain-textures-config-file/

- Installed this 3rd party runway texture package: http://flyawaysimulation.com/downloads/files/1407/fsx-airport-ground-texture-upgrade/

Then, I had flashing runways, so I installed this: http://www.lockonfiles.com/files/download/2612-fsx-dx10-shader-fixers-v322/

Then the game began freezing and crashing within a few minutes every time I ran it.

I have since put the original files back in the Textures, etc folders from my backups, and disabled DX10 Preview. Still freezing within 5 minutes of flying every single time.

Then, I rebuilt my FSX.cfg file using this tool

Still the same problem.

You should let FSX itself rebuild the fsx.cfg. You should not need a tool for that.

Are you using FSUIPC? I think the g3d.dll error you are seeing is the one that FSUIPC

will correct. Sometimes driver issues can cause that error, which is scenery related,

but being as it ran OK for a while, the driver may not be the problem.
