It started a week ago. What happens is as soon as you turn the power on ot stays on the start up screen continuously flashing NOTEBOOK over and over again. It won't go into the main screen.
That's not a notebook, it's a tablet, what is flashing is probably "NEXTbook" not NOTEbook. Since it's a tablet you don't have too many things to look at for the issue, first try doing a factory reset, which will wipe the thing and set it to factory new state. It will have a button press combination listed in the manual or support site how to do that.
If that does not work, contact the vendor for support, it's likely something is damaged.
