Has anyone else experienced this and if so how did you fix it?
Hello @MortTZW,
Typically when MSFS crashes, it will result in an application termination (crash to desktop), but your PC will still continue running normally. An application freeze followed by a reboot of your PC is possibly an indication of an underlying issue with your computer’s hardware, such as your CPU or GPU overheating. When MSFS freezes on you, are you able to alt-tab to other windows or press ctrl-alt-del to open Task Manager or has your entire PC locked up?
Thanks,
MSFS Team

I’ve seen a failing power supply cause an instant reboot.

Hi the entire PC locks up, no alt tabbing possible then reboots
Hello @MortTZW,
In that case, it sounds highly probable that the issue you are experiencing is with your PC itself, not with MSFS. These can sometimes be difficult to troubleshoot, so good luck! Please post back here if you’re able to figure out what was causing the problem.
Thanks,
MSFS Team
Mine was doing this for several weeks last spring - it was a failing power supply that was the culprit. I also needed a more powerful one, so it permitted some ‘overhead’ when really putting the system through its full paces. Has never happened since I replaced it, thankfully.

Can’t offer any help, only sympathy…
I have the same thing - only occasionally, perhaps 1 in every 3 flights though. Mostly when I go out of MSFS to start something else like YouTube or Spotify. Then - bam - reboot. So far I’ve not had a problem into a flight, only at or near the start.
I have a water-cooled CPU & GPU so not overheating; routinely check RAM (been bitten by that before!) and nothing else indicating a problem. Power supply could be the culprit as commented I guess.
For me, it’s not often enough (yet) to tear my PC apart. I haven’t had the same thing with anything except MSFS, but I don’t think I run any other program that stresses the PC as much.
Hope you get it sorted!

I had this last year (spontaneous boot) and found that I was getting 0x000000116 errors in Event Viewer. I’m sorry to have to tell you this, but Seedy could be right. When that happened to me, I had to send my card in for service. You could check the temps to see if they’re extremely high and go from there, but definitely check the Event Viewer.
I know this is a simplistic question, and I apologize, but some people here (myself included) are not PC experts so I need to ask. Did you actually reboot or just lose your screens? A problem I’ve had lately is that my screens go black - not a reboot - just all three go black and never recover. My PC never boots though - the CPU just sits there like nothing happened. It hasn’t happened over the last few weeks ( 
well there I go jinxing myself) but if or when it happens again, I’m going to try to reload my drivers by pressing the Windows key + Ctrl + Shift + B to see if that brings the screens back.

Thanks for the hint. My power supply should be easily powerful to handle MSFS but of course there’s the possibility that it’s faulty. I will get it checked out and post a solution in this thread if I can find one.

I haven’t seen your particular issue on my system. I get a screen freeze after about 5 mins of flight, can still hear sound echoing then after another few minutes the fans go crazy and the system reboots.
Weirdly I had the same issue last Nov (after SU6 I think) and after a lot of investigation, some system tweaking and nVidia driver rollback the sim worked fine again until now. It’s strange that it should recurr but I think I have done everything except change hardware so will get that properly investigated shortly.
After further stress testing of my system it looks like the problem of FS freezing after approx 5 minutes of flight and then rebooting was down to a faulty DRAM controller.
Replacing the motherboard seems to have fixed the issue.
Thanks to those who pointed me in the hardware direction.
