How to enable TPM

Hi, regarding your query I suggest to link Mai official link to get better understanding about your motherboard tpm settings. Below is the link.

MSI TPM settings

 

TPM enabled in BIOS but not showing in Windows

I've been having some issues with my PC of late (BSODs), and noticed my TPM version was 1.2, so I decided to upgrade it to 2.0.

Checked the manufacturer's website and downloaded its most recent TPM2.0 firmware upgrade.

After I dealt with ownership, running the upgrade provided another hurdle, had to clear the existing TPM, so ran tpm.msc and cleared it from there.

Found instructions on this page:

How to Successfully Update the TPM Firmware on your Dell Computer | Dell Australia

Then ran upgrade again. It looked like it was working (it did the reboot and then who knows what else) but then next in Windows there is no longer TPM visible under "Device Security - Security Processor" (running tpm.msc again it now literally says "There is no TPM available").

All online help talks about enabling it in BIOS, but it is enabled in BIOS (and always was). BIOS still showing TPM v1.2.

I also tried finding TPM in the Device Manager, as this is what I can find online: "The Trusted Platform Module should show under Security devices in Device Manager". But my Device Manager has no section called "Security devices"; also checked under System Devices, nothing at all with the word "security".

The "Other Devices" section has many lines (66 entries called "Base System Device",1 entry called "PCI Device", 6 entries called "Performance Counters", 1 entry called "SM Bus Controller" and 1 entry called "System Interrupt Controller") but for none there seem to be drivers, so potentially one could be TPM...?

Hardware: Dell Precision T5810 with an Intel Xeon 2680v4 and 32GB ECC RAM - BIOS on latest version.

Software: Windows 11 Pro 21H2 build 22000.2538 (the PC came with it; was bought as refurbished).

Windows is activated; Activation State tells me "Windows is activated with a digital license linked to your Microsoft Account".

Windows 11 itself (still) works fine, but it won't allow upgrade to a newer one (its update facility doesn't see any newer Win11 flavours).

It does allow for security updates.

If I try to run the TPM2.0 upgrade again it says there is no TPM; also tried an older version of the TPM2.0 upgrade, same issue.

The exact messages:

First "Error: The System TPM Query Failed, Aborting".

Then "Error: Unable to prepare the TPM update payload".

So the main question is, how do I get Windows to recognise that TPM is actually there (as it's enabled in BIOS with all the proper checks enabled as well). An additional question is, has anyone gone through the same scenario on identical/similar hardware and managed to get it to work and - if so - what were the steps to manage it successfully?

Thanks in advance.

<EDIT> checked via PowerShell, and it confirms that Windows is unable to detect anything to do with TPM

PS C:\Windows\system32> get-tpm

Before I ran the firmware upgrade it did have stuff there.

 

Windows Security says "There is no TPM available. Please check BIOS settings."

Hello GRCurmudgeon, KMLaw, stuck777,



Good to see you in Microsoft Community.

Firstly, you can refer to the steps of Enable TPM 2.0 on your PC (microsoft.com) to turn on TPM, or follow the specific steps provided by your equipment manufacturer, click the link below to view the specific steps.

[Motherboard] Which ASUS model supports Windows 11 and how to setup TPM 2.0 in BIOS? | Official Support | ASUS Global

How to Enable TPM on MSI Motherboards Featuring TPM 2.0

@KMLaw, however, I was unable to find a description/article on Enable TPM 2.0 on your device manufacturer's website. If you have not been able to successfully implement TPM 2.0 on your PC (microsoft.com), I suggest you visit Support | iBUYPOWER® for further technical support at your device manufacturer's official website.
