Help??? Why am I getting a green screen when trying to watch films? I've got Windows 8.1 by the way. Sometimes when I try to watch films or video clips on 'iPlayer' or 'YouTube', I get a green screen....this is SO infuriating!!!! sometimes I can watch a film or video clip....no problem. Other times all I get is a green screen...why?!?!?! My monitor isn't green, no, no.....I mean the film or video itself won't play. I get sound, I just don't see any picture sometimes, why oh why???
