Reboot Problem

[Han]

First, try clearing your memory. I believe this can be done using [ON] [A] [F]. If it doesn't help... read on.

If you have not already backed up the calculator, I recommend doing so. And I would recommend backing up each individual program/app/note and not the whole calculator. That is, back up the parts. Otherwise, a normal backup could possibly just be saving the problem that gets installed back onto your calculator with a restore.

Then, format the calculator. During a warmstart ([ON][Symb]), hold [A] [C] [O] to get to the flash utility (option 4). Then select format. To exit this interface, force another warmstart ([ON][Symb]).
