Is my HP laptop a piece of junk?

I bought an HP notebook about four months ago. It has Vista and everything seemed to be going well. Then yesterday out of the blue the hard drive crashed. I have anti-virus that I run regularly, I have spy-ware stopper that I run regularly, and I don’t go around the internet willy-nilly downloading potentially dangerous stuff. So what’s up with a hard-drive crash so quickly. Could it be Vista? Is this just a fluke or did I buy a paperweight?

I have spoken to HP and a new hard drive is on its way – at no cost.
