I have a TPM Module on an old Dell Precision T5400 which I am trying to enable under Windows 10. Unfortunately, windows is hanging on boot at the splash screen after I enable TPM in the BIOS. Does TPM need to be enabled (and activated) prior to installing Windows, specifically win10? I have tried several steps to enable it and none of them are working. I started with a Win7 install then upgraded to 10 and would rather not do a fresh install if there is a way around this - especially if I will get the same result. I've also applied driver firmware update from Dell to upgrade TPM 1.2 to 2.0
Attempts thus far: 1) Enable TPM in bios without activating - Won't boot 2) Enable TPM in bios plus activate - Won't boot 3) Disable and deactivate TPM - Boots successfully
