Videos won't play on Facebook and Live Feed Videos won't play on Youtube

I have a Lenovo Laptop and since upgrading to Windows 10 my facebook newsfeed videos won't play and I am having to view them on my iPhone Facebook app and then I watch a Live Feed that one of my local news stations does and that just gives me a black screen and a buffering circle and doesn't seem to want to load.. so can anyone help me please..

Thank you in Advance
