Boot failure, sudden restarts, glitchy screen, and unresponsiveness.

So the other day, I left Ndless on my calculator too long, and I took it out to find that there was a glitched screen left on all night.

• TI-Nspire CX CAS
• OS 4.4.0.532
• Had Ndless installed (4.4.0 r2007)
• Hardware revision O (0?)
• Was using nPDF

• Sudden restarts
• Glitchy screen (Usually during restarts)
• Does not respond to resets when reset button is pressed
  • Restarts when disconnected from computer (Battery?)

• Reinstall OS.
• Delete, then reinstall OS.
• Take out and put back same battery.

I would give images, but due to the buggy nature of this problem, it simply won't cooperate.

Update (8/16/17): Today my TI-Nspire CX CAS gave me a glitched TI-Nspire Classic boot. Of course, it glitched, but still, it was something.

Edit (11/20/17): My calculator doesn't turn on anymore. Help!
