When I start up my PC, I get this BIOS message that says, 'New CPU installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed.' It suggests I can press Y to reset fTPM, but warns that if I have BitLocker or encryption enabled, I won't be able to boot without a recovery key. If I press N, it continues to boot but won't enable fTPM on the new CPU. I haven't installed anything new recently—just played some modded Minecraft and worked on a NodeJS project. I chose N when prompted, but I had to reset my PIN, and after a Windows update, the message came back. What should I do?

This message usually pops up after a BIOS update or if the TPM firmware is acting funky. It might also think you've changed your CPU when you haven't. I recommend resetting the fTPM. You can do this by rebooting and entering the BIOS (usually by hitting DEL, F2, or ESC). Once you're in there, go to 'Advanced' > 'Trusted Computing' > 'AMD fTPM Configuration' and set fTPM to 'Disabled'. Save and exit, then reboot and re-enter BIOS to enable fTPM again. This should help straighten things out.
Out of curiosity, what is this fTPM thing and what role does it play in my system?
fTPM stands for Firmware Trusted Platform Module. It's a security feature that handles encryption keys and keeps your system secure. If there's a problem with it, your system may not boot properly after hardware changes.
