Hi and welcome to SevenForums,
You forgot to say which browser is being used and which ones you've tried to use to test the issue with
Your spec's page also says your using windows 8.1 is this true ?

Modern browsers do not need flash player to be installed to watch youtube videos,
Disable the adobe shockwave object in manage add-ons,
In Internet explorer Gear symbol on the top right and manage add-ons,
Click on Show on the bottom left column and switch to Show all add-ons,

Export Favorites to html file before resetting Internet explorer/ just to be safe.
