Could be a faulty adapter

First double check that you have a secure connection at both ends. Next test with a different adapter. Or connect the display to another system, see if the symptoms follow the monitor.

If they don't follow the monitor it's either the adapter or the port. If you have another adapter, and the problem persists, you need a new logic board. You probably wiggle the cable to get it out, and that in turn weakens the solder joints from the port to the logic board causing intermittent signal failure. You can also test this if you bend the adapter cable and the symptoms stop. Of course doing that long term will only exacerbate the problem, so don't go getting any ideas.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
