Anytime someone comes here running Win10 and complains about something suddenly not working, I immediately suspect Windows Driver updates.
Unfortunately, Win10 automatically forces driver updates on all of us, without our knowledge, and without our permission -- and when this happens, a working PC is suddenly "broken". This might have happened to you.
You need to go into Settings, Update & Security --> Windows Update.
Then, choose Advanced Options --> History to see when updates were last applied. If you see any that include device drivers, those could be the problem. So, if you can, you should see if you can rollback the drivers that are causing the problem. You do this by going into Device Manager, seeing if the appropriate device is still listed, and if so, trying to rollback the last driver update.
And if that fixes the problem, then consider disabling future driver updates using the information in the link: http://www.tenforums.com/tutorials/15989-device-driver-automatic-installation-turn-off-windows-10-a....
Good Luck
