Ok it started reading no disk right when I got it out of the box, even when a disc was in it.

So, I took the top off and then turned it on, and the motor spun the disk a few times, VERY SLOWLY, not even making a full rotation. Is it supposed to just spin it very slightly, not even making a rotation, then stop, or when you turn it on should it start spinning at a somewhat fast rotation and not stop? I need to figure out what is wrong with it.
