Hard Drive? Its a new computer as in I bought it from Best Buy 2 weeks ago so i doubt it but how would I fix it?

Hello, I own a Vista and it freezes on an average 4-5 times a day being played for about ten hours in sessions of 3-5 hours. It doesn't get to hot and it has no obstruction to its fans, its a brand new computer designed less then 2 years ago, and I'm virus free while freezing occurs. The freezeing occurs when I'm on desktop, playing a game, on the internet and downloading anything. If it helps it seems to be an intel core 7, Nvidia Purevideo, Vista and I'm currently using Norton 360 as virus protection. If you could help me that would be great, and please be very in depth when you make instructions. Thank you.
