新的華碩主機板 安裝完出現 we detected a new processor... 這是被用過的

買了電腦零配件回來自已組，CUP AMD、華碩主機板，組裝完開機，跑出下列訊息
we detected a new processor which will change the data /structure of the storage space for firmware TPM.

If you did not apply TPM function,please press Y to continue, otherwise please follow instruction bellow:

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 previous fTPM record and continue system boot, fTPM will NOT enable in new processor.You can swap back to the old processor to recover TPM related keys and data.

版上有人換CPU跑出這些訊息，

買電腦時，店員貼保固貼紙，叫我看一下主機板有沒有問題，我看不出有什麼問題，

新主機板都會出來上面的訊息嗎，還是這是被用過的，

就上面訊息是要按Y還是N，還請各位大大解惑一下，謝謝～
