You can try seeing if you can start it in "Safe Mode" and see if that allows you access to the tablet. If it does, that means you have something on that tablet that is interfering with its normal operations and you need to locate and remove the problem.
If that doesn't work, you may need to try a "Hard Reset", but note that will make you lose all personal data on the device.
Here are the instructions for both.
To get into "Safe Mode" please do the following.
1. First turn off the tablet.
2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.
3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.
4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.
NOTE: Doing this will clear the data on your tablet, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the device.
Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset.
