Why won't my ipad turn on?

Hi,

My ipad was working fine until earlier, it froze and I did the hard reset. After doing it, it turned on but to my surprise, the screen was on set-up mode and was asking for the iCloud pasword. I tried to input it a few times but it still didn't work. Then I tried hard resetting it again but now all I get from it is the apple logo and then it turns itself off again.

I also tried connecting it to the iTunes on my laptop.

Do you have any suggestions for this?

Thanks,

Ian
