Watching videos on the net...Javascript

[mini-valver]

Every time I try to view a Youtube video, I get a message saying I either have Javascript turned off or I need the new version of Flash player. Click the link and try to download it and it says I already have the latest version. So, how the f**k do I check if Javascript is on/off and if its not that, why wont it work? Never had this before on this laptop so I have no idea whats going on!

Help!

You may need to enable it in here if it says you already have it

Says Java is enabled but also says not verified in the middle box? I'm a r****d with computers, lol
