Should I insist that Best Buy replace my brand new laptop?

I bought an ASUS laptop on Feb 20th. The next day I played with it for a couple of hours. I loaded Facebook, Firefox, and played with some of the settings.
Then it sat on my kitchen table until today.

First day of work was today. I was finally able to down load my yahoo email account…and after that I was just hit with pop up after pop up after pop up.

I received account info so I could log in to the MLS. When I’d try to set my cursor into the ID field, it hit me with a pop up. When I tried to set my cursor into the password field it hit me with a pop up.

I ran the anti-virus software they gave me with the computer. It found a lot of bugs. It said it cleaned them up and asked to restart. I said, OK, and it just hung up, on a screen that said not to turn the computer off.

After 2 hours it was still hung up.

What would you do?
