R52400gtoR55600, if you have not please install a fresh copy of W11. This includes formatting your C: disk. Talk to your MB vendor about the -55C reading. I do not understand; you say "WIN11 (without the 2.0 TPM Requirement) " and "fTPM/PSP NV corrupted/NV structure changed". It seems to me that the first should exclude the second. If F67b is a Beta BIOS (usually what the b means), try the latest non Beta BIOS. I am curious why you disabled the TPM function. John.
Firstly,thanks for repsonding.Well, i had disabled the fTMP Fuction on my motherboard when i had the ryzen 5 5600.also about the "WIN11 (without the 2.0 TPM Requirement) " was that the ryzen 5 2400g isn't supported on windows 11 and it doesn't have the minimun TPM 2.0 that's why i said that.my next step is downgrading the bios and windows on my machine
R52400gtoR55600, of course Ryzen 2400G is supported on Windows 11 all Ryzens are. OK you are correct (no TPM) but you could run W11 using rufus to write your boot disk with W11 to prevent it from using the TPM or buy a TPM module for your MB if it supports it. You should be OK on the 5600 with the TPM enabled. Please do not use Tiny11. You will need to Clear the TPM. I bought a TPM for my 3970X (about USD 20) and run W11. John.
There's actually an even newer BIOS for your board, F67d released last week 9/2. However as @misterj states, BIOS versions that end with a letter are beta and may be buggy.
You need F63 or higher to support the 5600. You could try F63 or F66 which are not beta versions. If you don't want to go backwards at least try and Load Optimized Defaults in BIOS or perform a Clear CMOS.
By "without the TPM requirement" do you mean Tiny11?
the ryzen 5 2400g isn't a windows supported cpu and doesn't have TPM 2.0,thats why i said that.but ill try to downgrade my bios and change back to windows 10
