I tried to enable the ptt/tpm 2.0 in the bios but everytime I restart my computer after enabling it, it revert to disabled

My specs are:

  • Microsoft Windows 11 Pro
  • Gigabyte B365M D2VX SI (version  :  American Megatrends Inc. F6, 2021-11-13)
  • Intel i7 8700 
  • 2x16GB Corsair Vengeance
  • 1000 GB SSD
  • NVIDIA GeForce RTX 4060

When you say it's reverting, is this immediate? You "Save and Exit," then when the computer restarts, the BIOS no longer has the setting?

 

Did you make sure you chose "Save and Exit" in the BIOS to save your changes? 

 

Did you enable Secure Boot? This might be required to enable TPM.

 

Did you disable CSM/Legacy Mode? This would be required for Secure Boot. Note that to do this, you'll want to make sure your SSD is using a GPT partition table and not MBR, as CSM is required for using MBR boot media.

Thank you for your answer. Yes I choose save & exit and the secure boot is on

It was a custom one from a small shop

Your CPU is officially supported by windows 11 and Windows 11 requires TPM to be enabled, for it to even let you install the OS. Why would the shop disable it, and install a modified version of Windows 11 to bypass the TPM requirement. Could there be some thing wrong with the TPM function in your CPU. According to your system info, under secure boot it shows, PCR7 Configuration: Binding not Possible and near the bottom Device Encryption Support. Reason for failed... TPM not Usable... 

Open up run and type in tpm.msc to check the TPM status. Go into bios and reset to defaults, the save and exit. Your windows will probably stop booting and system is going to spit out errors. Go back into bios and set it back to the way it was before, follow by enabling other necessary setting for TPM to work, then go to the TPM function section, and try to enable it. 

Still don't work or don't want to risk windows of not being able to boot up anymore, then look at your board, to see if there is a TPM header. This will let you install a TPM module, without having to fiddle around with the one from the CPU. For the add on TPM module, check pin layout cause there are 2 types out there.
