PC settings for YouTube
 

anyone got any idea how to fix a glitch on my PC , only had the problem for a couple of a days , used to be able to view the videos posted in the video jukebox thread , but not any more , same problem with other sites with a link to a Youtube video .(all I get is a blank screen with a small logo in top left corner .
Youtube works fine if I click onto the site directly , not aware that I have disabled any settings and no pop ups telling me to download an update or anything .

idiot proof, step by step instructions please
Thanks
