TPM missing on HP Pavilion 550 series desktop

[caking715]

I am having problems with my MS OneNote since 11/30/20.  I cannot connect with my accounts and get the error that "Your computer's Trusted Platform Module has malfunctioned" when I try to sign in to my work account.  I was using it fine on the 30th!  I searched for the TPM file and it doesn't seem to exist on my computer.  I have looked at the solution at https://www.micorsoft.com/wamerrors, but it doesn't help as I can't reset something that isn't there!

Error code:  80090016

Correlation ID:  0101b550-85d1-4ebc-982c-85e9049a2eba

Hi@caking715, Welcome to the HP Support Community! Request you to follow the below troubleshooting steps:-

To open it, press Windows+R to open a run dialog window. Type tpm. msc into it and press Enter to launch the tool. If you see information about the TPM in the PC—including a message at the bottom right corner of the window informing you which TPM specification version your chip supports—your PC does have a TPM

Hope this helps! Keep me posted.
