Windows 7 Professional 64 bit Flight Simulator X crashing

I can think of two possibilities.
1-It's one of your add-ons, possibly a AI traffic add-on.
2-Many have had problems when adding SP2.
The best way I have found to add SP1 and SP2 (both needed) is by a fresh install of FSX and adding The Acceleration Pack which contains SP1 and SP2, they seem to enter the Sim without any problems.

Let us know how whatever you choose help.

1- I do not have any addons installed.
2- The problem is happening with a fresh install and with any patch

Try lowering some of your memory eating slides such as autogen, shadows, clouds and AI.
For a last resort delete SP2 and see how it works.

I lowered clouds to an absolute minimum and I completely disabled scenery autogen, all AI traffic and shadows. I also did it again after I uninstalled SP2. Still not working

When is the last time you cleaned the dust out of your computer.
Blew the CPU and other fans clean.
Reseated all your ram and cards.
The machine needs occasional attention or it crashes when pushed to it limit (overheating)
If you don't know how just ask, and I or someone else will be more than happy to help.

Your problem is very baffling.

I cleaned all dust out of my computer last week.

I am suspecting that this is rather some absolutely weird problem with the machine trying to open in-game menus (no idea why could that be), not crashing due to overworking.

There have been extremely rare occasions where the pause menu did indeed open and I could close the game as normal without crashing and losing all my settings. I don't know how that happened, it was a miracle.

Every other game and program works perfectly on my computer. Only fsx behaves unusually running on 64 bit windows 7.

Is there any chance that my machine is not fully compatible with Windows 7 Professional 64 bit? If yes, how can I check that?

Thank you for your attention 🙂 It is indeed an extremely baffling, unusual problem

It is, check here.

How about cleaning out and changing your video card drivers.
Try the latest, if that doesn't do it try the one before what you are using now.

To check the driver number, go to start/search and type in "DXDIAG" without the quotes and you can read your system there.

When you rightmouseclick on the desktop FSX shortcut icon, a popup list should appear with options like [Troubleshoot Compatibility] and [Run with graphics processor..]. Go through all those tests and trials.
I found unchecking the Preview DirictX 10 option helped. Mine only crashes occaisionally now.

I found and downloaded the latest beta driver for my graphics card. I ran the game 3 times and it looks like the problem is GONE 😳 😳

It's been soooo soooo long since the problem started and prevened me from playing for so long

Thank you so much man 😀

👍 It took a while but you did it and I'm delighted.
Have fun!
