I recommend that you attempt to boot into Safe Mode:
It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.
Good luck and let us know!

OK, thank you.
Assuming your issue is not hardware (which is impossible to diagnose at an internet-distance), your next steps will be these rather drastic recovery attempts:
Hopefully you already have a good backup, as it is unlikely you'll be able to take one now.
If the problem is hardware, then of course there is nothing we can offer you to try...only in-hand evaluation by a qualified BB hardware technician could give you a proper diagnosis and estimate of a hardware issue.
