Just recently started experiencing a problem, Everything was perfect before. Using Crystal Light. During the flight, I take off the headset and do some other things. Then sudenly the comp turns off and restarts. I had never had such problem before. I cannot recal when exactly the issue appeared. Initially I thought that it was temperature issue (indeed, the CPU was hot). I upgraded the cooler, but the problem still exists. When I take off the headset, after 10-15 min the comp truns off. I did several flights more than 1h and everything was ok. But after I take off the headset, soon the comp reboots. The conclusion I made is that Pymax conflicts with the system after going to sleep mode or something simillar. Repeat, there were no such issues before. But most likely the problem appeared after MFS2024 reinstall. Or maybe it is just a coinsidence.

Yesterday I did 2h+ flight, but before leaving the cockpit I switched off the VR mode. Later got into the cockpit, entered the VR mode and everything was ok. I could live with this method, but previously there were cases when I had a sim crash after entering a VR mode after longer break (flying long haul flight). So, don;t want to risk :)

Maybe you understand the problem and have any advice how to fix the system crash after the headset goes to sleep mode?

I've never had the problem you are describing but I've had two Pimax Crystals and in both cases I had problems with the headset losing connection with the software that were related to USB power settings. I make sure to change all the related USB power settings in Device Manager so Windows won't shut them off to save power. Probably unrelated, but throwing it out there in the off chance it helps you in some way.

Thanks for your feedback. The ChatGPT also mentioned USB power settings. Will try that out. But for now I just reinstalled the Pymax Play, set the sleep mode for 20 min (max). But yet did not dare to check if it still causes problems. The passion for flights prevents me from experimenting :)

Later will go deeper into settings.

That sounds more like a power or driver reset than a normal MSFS problem to me. If the whole PC is rebooting, I would check Windows Event Viewer after it happens and see whether it is only Kernel-Power 41, or if there is a WHEA, USB, or controller error just before it.

The USB power-saving angle is worth trying, but I would also disable sleep and USB selective suspend temporarily and test with the headset idle on the desk, without MSFS running. If it still reboots there, you have narrowed it to Pimax, USB, or power management instead of the sim.
