Why does Youtube not connect and say "Google could not find Youtube.com"?

[949]

So I'm connected to the internet, obviously. That's how I'm asking right now.
But for some reason (And it's happened before) I cant connect to YouTube. So I have it starred and up on my bookmarked list so I can just click on it, but when I did, a page came up saying "Oops, Google could not find YouTube.com"
So I tried searching it on Google itself. That didn't work.
I tried searching via the address bar. That didn't work.
I'm using Google Chrome and I have a Compaq Presario CQ61 Notebook PC.
If anyone would be able to explain why this is happening and how it can be fixed, I would really appreciate it.
