Pc Keeps Freezing.

Windows 10 1803 all up to date.
Build attached.

Had a week or two of PC freezing...usually soon after morning start up.....have to pull the mains plug then restart.
Normally it will not freeze again that day and everything opens as it should....even if it is turned off and restarted one or more times in the day.

One complication is that before it freezes it often doesn't cleanly log into the internet (on start up)...it's on a WiFi extender....in the list of connections available I have to fiddle and perhaps disconnect then reconnect (for a clean network and internet start)....it gets the network but not the internet connection on initial start up!
Have run system file checks and a couple of hardware checks, memory and hard discs etc.

I have checked the events logs and only the one copied seems to be relevant:-

Am moving to a full reinstall of Windows 10 in the near future but it's not something I contemplate lightly!!

 

Thanks for that David I did try your suggestions.
Have been through most of the possibilities and had some luck with my Network Adaptor driver (USB).
Uninstalled/reinstalled, also changed the USB socket, and had 48 hours without problem.
Now back to simple freezes, normally just after start up.
Have also done memory and hard drive tests with no negatives.
May well submit the logs for scrutiny at Bleeping with their app.
Will work through my AV etc in the meantime.
