I have recently had the problem of the sim crashing to restart. I can run the desktop all day on the internet if I want to. As soon as I fire up P3Dv5, pick an airport, have an airplane, the PC crashes and restarts after about 3-5 mins.

Confused, I am. Anybody have any ideas gratefully received.

Have you put any new addons on recently ? if so uninstall it and see how you go

If you are saying your PC reboots, then that could be a loose connection on your hardware, a dry joint as it`s known as, when more power is needed it trips out and the PC re-starts check Event Viewer. 

Hello. No new addons lately. Appcrashview only shows MsSense.ex as a fault which is something to do with W11 defender. What should I be looking at in the event viewer?

Note the time of the crash. Then right-click on the Start button and select Event Viewer. Click on the arrow next to Windows logs, then click on Application. Now, in the top center pane scroll down to the time of the crash and look for entries titled "Error". Copy and paste any such entries here.

I would also say check that your power supply fan is running as well. I had the issue a few years ago where the PC would restart if it ran any graphic intensive application and I found on observation that the power supply fan had stopped working.  I got it replaced and it was smooth sailing since. 

All the errors seem to indicate the same thing, MsSense.dll from the Windows defender advanced threat protection in W11. So it is a windows problem.

Have you excluded P3D folder from WD?

Temporarily turn off Defender and try again.

Are you running P3D with administrator privileges and you should not put in Program Files(x86), Defender will protect this.   

Hello people thanks for your inputs. I have just gone back to W10 from W11. That surprise, surprise, made no difference. Looking elsewhere, I have come to the conclusion that the graphics card is not well. As said before the PC can stay on for hours with no load. Start the sim and after 3-5 minutes the PC crashes. The temperatures do read normal, about 60 C, however the upper surface of the graphics card are extremely hot. Event viewer and appcrash tell me nothing. I am coming to the conclusion that the card is becoming faulty.

Try a stress utility like furmark. (https://geeks3d.com/furmark/) it may give useful insight if it is the card. 

I have tried the furmark stress test on the graphics card. It seems fine. I ran a intel stress test on the CPU @ 4.9 and that appears to be fine surviving on 100% load with temperatures in the low 70's. However, firing up P3Dv5 the PC crashes after 2-5 minutes. Lowering the OC to basic 3.7, it still crashes after about 10 minutes. The crash report in event viewer is a critical 'kernel-power 41', which to me is a foreign language. So is it the CPU ?

When I google it, the following comes up......................

This sounds like either a bad power connection to the GPU or a bad/overloaded PSU.  It could be a failing GPU as well.

Make sure the aux power connectors on the GPU are connected, and at both ends of the power cable(s).  I'd recommend removing and reseating them  What CPU/GPU are you using and what power supply is in the computer?
