Well, after messing with drivers, reinstalls and etc., it turned out to be something so simple. My old card had a full sized HDMI output and my new card had a mini HDMI output, which I didn't have a cable for, so I just connected my new card to my monitor with a VGA cable. Out of frustration, I went and picked up a new HDMI cable that had a mini on one end, so I could use it with my new card. THAT WAS IT! Somehow, the NGX didn't like using an analog cable! I was wondering why my old card kept working...every time I reinstalled the old card, I also used the HDMI cable. Aren't computers the most frustrating thing?! Oh well, all is good now. Thanks for all the help!

Any other suggestions for me? Should I use some driver cleaner program? I just uninstalled the driver through the control panel and used the auto installer from NVIDIA.

I did that, too! Rolled back to VGA and then reinstalled nvidia drivers.

I'm not sure what a Shader Cache rebuild is. I did just uninstall and reinstall the entire package and nothing changed. The NGX still loads up and the VC looks great, except it's cold and dark and clicking sswitches either do nothing or crash and restart the sim. Again, the only differnce is the new gt640 video card with the same newest NVIDIA driver as the GT620. NGX was working perfectly until the new card.

I deleted my cfg and still nothing on the NGX. My new cfg looks fine and only one video card is listed. Perhaps I should uninstall and reinstall?

Yes, those are the driver I'm running. I am running as admin, but will try rebuilding the cfg. Thanks! Only reason I'm concerned is all my other add ons are running perfectly.

Thanks, but they are the latest drivers from NVIDIA and the same drivers I was using before installing this new card. The card is barely an upgrade.

Thanks for the quick reply, but the plot thickens! I cannot click on anything. Overhead switched no longer work, etc. I was able to click to lower the yoke, but it crashed the sim. It's clearly something with the video card. I'm using the same exact drivers that I was using on the older card last night and everything worked perfectly, as usaul. Everything else in FSX works as usual. The NGX is the only problem since installing the new card. Thanks again! I loaded again and tried to rotate some nobs on the a/p. Crashes every time. Never had this happen with the NGX.

I loaded up the NGX after installing a newer video card. Just went from a GT620 to a GT640, so no big deal. Last night, the NGX loaded up ready for take off as usual (do not have time for the whole start up thing). After just now installing the new video card, FSX loaded up perfectly and so did the NGX. Problem is it's cold and dark. Is there some setting I may have accidentially changed? I'd like to get back to the NGX loading in a ready for take off state. One more dumb question: Been awhile since I looked for the manual that came with the download. Any idea where it's located on my computer? It would be in the default location that I cannot remember.

I should have added that other add ons, such as PMDG 737, still load fine with no problems, so I'm certain the 767 uninstall took a critical file with it.Thanks again.

Been a long time, so I dusted off FS9 last night. Fun fun!Long story short, the level D 767 was acting weird, so I deleted it. Since I deleted it, all of my Flight One products cause a CTD as soon as I select the airplane. I'm assuming the Level D uninstall took a critical file that the other Flight One products need. I'm specifically talking about the DF 727, Super 80 and ATR. The Super 80 loads but all the guages are frozen and nothing responds. The other two sims just crash FS9.Thanks in advance if someone can help me!Sorry I posted here. I lost track of my Flight One log in info. It has been years!
