Problem solved - my computer fairy did it!!!!!!!!!!!!!!!!!!lol I just went back into you tube and i can now watch a vidoe with no interuptions!

I wonder if if has something to do with the fact that this morning I mistakenly disconnected myself from the server. When i was trying to access the internet it kept saying something about no server found! I coulnt get into the internet so I switched everything off and then back on again and the computer has reconnected itself and since then the speed its working at is amazing!
