Computer Freeze_ups

[mkroc]

I installed windows and NPVR on my current computer a year ago. After about 6 months I had trouble with frequent computer freezing (blank screen and not responding to inputs) and considered that I may have had an issue with an well used video card, and the event viewer show a couple of errors.
Last month I removed the card, reinstalled Windows 11 and NPVR. Things ran very well until this week and two days in a row I had to reboot a non-responsive computer. I can not tell from the Windows logs what time this may be happening, and the only errors I see are com related to NPVR? The computer in question is just used as a media player (NPVR and occasional videos). Windows update is on automatic.
I ran disk and memory diags on the computer and it looked ok.

Is it possible for someone to see if there is any info in the logs that may help, even though it does not seem to be an issue during active recording?
log should be attached mkroc logs 9_16_26.zip

Thanks

I see you have a lot of channels that aren't mapped to Schedules Direct which use OTA and some of those OTA channels aren't mapped to a guide. it probably is to your advantage to map those correctly.

Where I suspect things are going wrong are scheduling wakeup but the best thing to do is to paste the actual error(s) from the event log.

Thanks for looking at this


All along I have only setup Schedules direct for the few OTA stations that I watch.
I will start setting up the rest if that is required for error free operation.
Would it be just a valid to delete the 40 odd stations I never watch?
Thanks for your help and advice

That doesn't seem to be an NextPVR error. The times I would check would be around 2:25 when

Badly mapped channels aren't a source of problems exactly but you have so many that these take an extra 16 minutes. I would think you'd want NBC to have better data.
