Some users have said they see an fTPM/PSP NV corrupted message when they boot up their PCs. They can’t boot into Windows because of the fTPM/PSP NV error, but others see the same message again. So, let’s find out how you can fix things.

How come the fTPM/PSP NV corrupted error occurs?

The fTPM/PSP NV error message references an fTPM module, which is the main cause of the issue. That’s a type of Firmware TPM (Trusted Platform Module) implementation for encrypting system drives with BitLocker.

Therefore, the fix can often be to reset fTPM on your PC. However, some users need to disable BitLocker to reset fTPM. You get two options here:

  • Press Y to reset fTPM. If you have Bitlocker or encryption enabled, the system will not boot without a recovery key.
  • Press N to keep THE previous fTPM record and continue the system boot. fTPM will not enable in the new CPU, you can swap back to the old CPU to recover TPM-related keys and data.

The first option will reset the fTPM. And many ask, what will happen if I reset fTPM? The answer is simple. If you have Bitlocker enabled, don’t do it without turning off encryption first.

However, some users continue to see the fTPM/PSP NV message even though they can enter Windows after selecting Y. Some users who press the N key get prompted to enter a PIN, but things don’t always work.
