Windows 10 has very recent changes. The most common issue I run into is allowing Microsoft drivers.
Roll them back. Use System Restore to when it worked and block driver changes.

A couple of days ago my internet cut out unexpectedly (only on my wired PC) it took me a good hour of resetting various devices to get it going again. The following night, same thing happened, this time I had to uninstall my network adapter and reboot to fix it.
Today, nothing works. I've tried all the previous fixes and I get no connections available, limited connection, or connected to Internet, but anything that actually uses the internet just crashes.
It also is no longer shutting down properly, if I hit shut down it goes through the normal motions, the screens shut off, but the computer is still running for a few minutes before it boots back up to the log in screen. So far trying to shut it down at this stage has worked.

Most recent hardware change was months ago, no recent changes in software.
Any help would be hugely appreciated.
