Hi yeager anna,
Since the calculator operates slowly even after the RAM has been cleared, I'd say, "Your OS must be corrupt." You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix this problem by installing the newest
Ti 84 Plus 2.55v. MP OS, operating system. Use fresh batteries when installing the new OS. If you need additional instructions your welcome to read my Ti 84 Plus solutions. I pretty much tell how you can install the new OS with another Ti 84 Plus calculator or, connecting the computer to the calculator to install the new OS. You can view my solution to install OS by clicking, "
Ti 84 Plus OS installation." Just stroll down to oneplusgh's solution at that posting and, I cover a lot of topics you may need advice on to install the new OS.
If you need instructions to downloading and installing TI Connect on a XP or, Mac computer click,
"TI Connect on a XP or Mac computer." I realize this posting was for a later OS but, this link will take you to the latest TI Connect software and, newest OS too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."
If you need instructions to downloading and installing TI Connect on a Windows 7 computer click,
"TI Connect on a Windows 7 computer." Just follow Procedure 3. You can also get instructions at this link on how to install the Ti driver to link computer and calculator. I realize this link instructions were for a Ti 89 calculator but, they will work for a Ti 84 Plus too. Once you get the TI Connect software installed come back to this posting and, follow the instructions above at "Ti 84 Plus OS installation."
My instructions is geared to save you a lot of hardship. No matter if your having to install Ti Connect or, the newest OS for your calculator. I do not use TI
OSDownloader because, TI
OSDownloader might not give you the newest OS for your calculator. My instructions will. If you have any questions just post a comment and, I'll respond quickly.
There weren't any.
