TPM Authentication failed. (0x1)

HP Recommended
HP EliteDesk 800 G2 TWR
Microsoft Windows 8.1 (64-bit)

After resting BIOS defaults I am unable to boot up my EliteDesk 800G2 S.No. [edited] and I am stuck at the WinMAGIC Drive encryption LOGIN  screen where despite entering the correct password I keep getting the error message : TPM Authentication failed. (0x1). I am getting the same message when entering the security questions.
