Hello, @Willejust
According to the steps in [Motherboard] Which ASUS model supports Windows 11 and how to setup TPM 2.0 in BIOS? :
1. Press "Del" when the ASUS or ROG logo appears to enter the BIOS.
2. Go to Advanced\PCH-FW Configuration page and enable "PTT".
3. Once you attempt to make the change in the BIOS, a notification box will appear (see below). Just click the OK button, then press F10 to save your changes and reboot your PC.
May I ask if the PTT wasn't correctly enabled after saving the settings?
We recommend referring to the instructions in [Motherboard] How to install Windows 11? to ensure no steps are missing or incorrect.
Also, if your BIOS hasn't been updated to the latest version 1904 released on February 16, 2024, consider updating and clearing CMOS before checking again.
Thank you.
