Sleep WakeUp, PC shuts down instead

[FM5]

I would think this is a Windows 10 problem not an NextPVR problem, but it's still doing it after I had Windows 10 do its full reinstall, and swapped power supplies, and put the hard drive into an entirely different PC.  

NextPVR had been working great as it basically always has.  Until a few or so months ago it started missing recordings.  The PC goes into sleep mode, and wakes up fine to record, sometimes.  Seems like after a reboot, recordings will record properly and go to sleep and wake up for a day or two or three, then the PC won't wake up for anything after that -- including me trying to manually wake up by moving the mouse or pressing a keyboard button like usually works.

That last part makes me think it can't be an NextPVR problem -- unless NextPVR sometimes tells the PC to shut down instead of sleep.
------------------------------------------

So, apparently, the PC for some reason shuts down instead of going back into sleep mode.  Or shuts down while in sleep mode.   This PC is 95% only ever used for NextPVR to record TV.  There's not much that should be changing anything with it.   

The bios sleep settings were the same as always.  I tried a different power supply.  I let Windows 10 do its own full reinstallation, and then I installed all programs fresh, including NextPVR.  I had saved 500GB of TV recordings NextPVR already did and then copied/pasted that 500GB back into a NextPVR recordings folder, but that shouldn't matter.

It still did the same thing.  The computer works fine for a day or three, then it apparently goes into full shutdown instead of being in sleep, and I have to turn it on with the power button, and it does a full bootup and works fine for a day or two or three again.

Maybe it's a motherboard problem.  Yes, it's not recommended, but I removed the hard drive and put it into an entirely different PC.  Same thing happens.  So it might be a motherboard driver problem, but it's not a motherboard problem.

If you can rule out it's not related to NextPVR, that'd be great.  Figured I'd ask before doing yet another full Windows and apps reinstall on the alternate PC.

Also set the hard drive power-down minutes to 9999 since I read that helped someone with a similar problem.  No change.

NextPVR doesn't tell the system to shutdown but I do see the system was shutdown here

2024-05-07 16:52:20.023 [DEBUG][7] /shutdown...

and it wasn't restarted until early today

2024-05-09 01:16:08.350 [DEBUG][1] No C:\Users\Public\NPVR-data\scripts\PreStartup.bat

The 7th was patch Tuesday and as it turns out I have an update at very near that time, perhaps you didn't tell Windows to restart.

If I ever manually shut down that computer, I always restart it immediately after, since 95% of its use is for NextPVR. So the PC is supposed to always either be on or in sleep mode and never off for more than five minutes.

Yes, I restarted it today. And that's when I saw it missed the last two(?) days of recordings. Today I restarted it about 10 minutes before NextPVR was scheduled to record a TV episode. And then it turned on as expected since it had been restarted recently.

I mostly assumed the problem is with Windows 10 auto-changing drivers of something during a Windows update instead of it leaving things alone. I tried a different driver for Intel Management Engine(?) which internet people often point to as creating sleep problems. Nope. Windows 10 apparently has that driver built in, but I tried the Windows 7 and 8 versions from the motherboard site (ancient Biostar TZ68A+) since those used to work fine. Nope.

How would I tell Windows to restart after a patch? It's always been automatic. And do you mean a Windows 10 patch, or a NextPVR patch? I'm guessing you mean Windows since I thought NextPVR patches are all done manually. Maybe it's shutting down after an update, if an update happens every three days or so. I don't see anything in Windows Update settings other than "restart this device as soon as possible when an update is available."

I meant windows patch but you can check the Windows event log to see what when on between the 7th and the 9th. I already said NextPVR doesn't shutdown but I can add you are correct and it also doesn't install patches automatically.

Your tuner driver could also be crashing Windows which is like a shutdown. The Windows event logs might show more.
