As Subject states.

I have done everything to try and fix this. 
Re-installed Sky Go, turn pc off/on etc reset router

I called on phone and adviser was like its your PC, no it is not my PC coz i can watch adverts on the app all day long but i cant watch a programme.

All i get is a persistent black screen with the sound of what ever programme i am wanting to watch.

When the blank screen loads up try putting your cursor on one of the corners of it and then try dragging it to make it bigger to see if that then loads up Sky Go.
