My setup is very similar. I have ddr4 instead. Never had any issues until the upgrade to Win11. CTD every flight about 20 minutes or so after takeoff. Especially after I'd leave it at cruise altitude only to come back to the sim not running any longer. I tried it all from emptying the community folder to graphics settings to removing GSX Pro, FS realistic and marketplace purchases to rolling back the nvidia drivers.

What ended up as the fix was individually going into every single device from the device manager list and unchecking the box to "Allow the computer to turn off this device to save power" for any device that has this option. I went through each and every device to uncheck the option as I don't think there is a way to disable the option to all devices at once. At first I got a CTD again so I went back to the list again only to find that I missed one. I can't say with certainty if that will work for you but that seemed to be the culprit for my system. I've had a week of simming with no CTDs with all the addons added back to the sim.

Agree with the concensus above, get rid of the Norton bloatware. A bit of sense and Windows Defender, your machine will run a lot better for it.....

It could by a Realtek Audio driver.  I was having CTD issues and that turned out to be the culprit.  Don't remember the exact name but in "Programs and Features" i saw some Realtek driver that I installed prior to CTD and removing that resolved the issue.  And yes, get rid of Norton.

Ditch any thrid party AV program and just use the microsoft defender and firewall. That's all I have used for 13 years and have never had any problem. 

I have never had a CTD with MSFS, however last night when I powered it up there was an update waiting. I did the update, then did two local flights at my local airport, and got a CTD with each. I have not done ANY troubleshooting at all yet, but it is possible that there could be something with the latest update. I am not saying that there is, but I would not rule it out yet.

Windows defender is  better than nothing, but not if  you really want security. Malwarebytes is for after your AV has dropped the ball, and you have been infected, and may not wipe everything out. 

Windows defender and common sense is the key to all the security you want. I've been using my pc without a third party AV since Windows 7 with no issues. Most problems with security/viruses is user related.

Nah. You need to completely remove every single thing in your community folder and whatever was downloaded from the marketplace. I mean everything.

Even small addons can conflict with other ones.

More information: Does this happen on a different route? Temperature of hardware? Any issues with USB's turning off or on?

Thank you everyone for the replies so far,

First step for me will be removing Norton completely and sticking with windows defender. I will try the flight again and see if that makes a difference and then continue to troubleshoot.

I have checked all temps and done some stress testing and they all came back fine so at least that is one thing.

Totally clean MSFS install?  Does it happen on that case?  Or disable all addons (temporarily move them out of Community folder)

 

Little update:

Removed Norton 360 and CTD still occurred. This time after 20 minutes. Going to to fun troubleshooting this one! Also, made sure USB devices would not power off. 
 

I’ve now read several say to remove Realtek driver so I have done that. Jumping back in to text again. 🙂

Yep, along with a clean windows 11 install. I did a full format as I thought possibly something was corrupt. With no event log and very limited installed on the pc, it is becoming increasingly hard to pin point. More so that all hardware is passing tests without any issues showing too.

Temps all good, all stress testing remained stable. 
kinda wish one would show an issue as I’m running out of ideas what on earth could be causing it! 
Thank you for the reply

Not having any event viewer log for the MSFS is really weird, Windows automatically creates these any time an app/program is terminated without user intent. It does indeed seem like something would intentionally close MSFS and making it seem like it was the user (like "close" in the regular way, ALT+4 or hitting the X in the window). I'm not a malware expert but I'd start looking there, also anti-virus could maybe do something alike.
I'd rule out hardware failures, those would create event logs (or bluescreen you). Overheating does not make the program fail, the GPU or CPU will throttle down long before.

Also this might sound strange but do you live alone and are sitting at the desk the whole flight? So it's not like a curious child or cat could play tricks on you?

Hey,

thank you for the reply. 
the only thing that has ever popped up in the event log is couatl64_MSFS.exe. However,  I chased this up with FSDT and they have told me it can’t crash the sim and the log is a result of something else causing the sim to crash.

Hmmm

I'm thinking hardware with a totally clean install but hard to say for sure.  What about a BIOS flash?  Is it updated?  Try reseating your RAM.  Swap PSU cords?  I've had a bad 3 prong power cable before .  Even try a different outlet in your house.

You probably already did but double check everything is connected to the motherboard nice and solid.
