Have you got a Micro SD Card for it? If so format the sd card as fat32 and follow the instructions from the Quote in this post. It should start an update procedure and then you should be able to boot your tablet.

P.S. If you only just got it, it's good to leave it on charge for a while overnight 24hrs to ensure it charges up. Usually if the battery is too low to boot up it will vibrate and not boot when you try to turn it on.
