Good day, everyone.
Several times I have set my PC to render some odd 12 - 20 episodes in the evening, only to be met with a fresh desktop environment and closed Vegas open in the morning and only 1 episode rendered. There is no crash report window of any kind.
I suspect that it's windows restarting to update because it assumes that if the mouse isn't moving then I must not be using the computer but I don't know for sure. Perhaps just Vegas crashing and not reporting?
Vegas 18 Pro
What does the system log show? It should say why the PC rebooted, or at least what it was last doing before it rebooted.
I have never had Windows reboot without informing me. I would look into possibly a heat problem or Vegas crash.
I allowed an update to my media server today right after my wife's soap opera finished recording. I was mowing the grass and she was playing with our grand daughter.
If you're worried about a reboot to install Windows Updates you could Pause Updates for Seven Days or Change Active Hours.
"I have never had Windows reboot without informing me."
It could happen on an unattended workstation.
@john_dennis I guess, but I have never had it happen.
Type 'view reliability history' into windows search bar, check what it says. Normally when I had to do overnight renders with Vegas it would stop Windows going to sleep EXCEPT, if the render stalls, stuck on 57.1% etc, the computer will then go to sleep after whatever idle time you have set. But if that did happen, you'd see a stuck Vegas when you woke your computer up. From your description your computer is restarting
You have to 1st set the power policies to 'never' for sleep and shutdown instead of an inactivity timer when under power rather than battery. Then either go offline, suspend Windows updates, or disable WinUpdate restarts completely via gpedit.msc. There are other ways to disable auto restarts completely like with PowerShell scripts and regedit but they do the same thing as gpedit which is how I prefer to do it... disabling the restarts that way lets the security updates and virus defs download and get applied if they don't require a reboot. While you'd at it, I also recommend using gpedit to disable WinUpdate driver updates although DDU has a convenient option to do the same thing if you use that. You can google for details on the various procedures. I only suspend WinUpdates when I want to stay online for remote console or file system access, but don't want anything downloading while I'm running benchmark scripts.
If you suspect it is Windows restarting to finish updating you can look in the Update History within Windows Update to see when any of the various auto-updates occured. These give you the dates but not the times of day.
If you go into Advanced Options you can toggle on "Notify Me When A Restart Is Required To Finish Updating". However it will still complete the update if it thinks you are not in Active Hours. So also specify what your Active Hours are e.g. I set mine to 6:00am to midnight.
Initially I wondered why you needed overnight to finish rendering, perhaps an old PC. My current renders in as little as 1/10th of the real time on the RTX3060 so an hour may be 6 minutes on a 1080p multicam project of 1 hour. But you're on an RTX3070 etc so all should be fine.

It's usually batch rendering about 7 o 15 episodes using the batch export script. also MKV footage so no gpu acceleration.
Mine rebooted a couple nights ago on its own. I was not rendering, though, as I don't render overnight. I'm sure it was Windows installing an update that caused it to reboot.
