    yep agree with GoldenVenom-1067 the SCEP error still exists, though as each individual receives this error differently, I thought mine was fixed, just played the technical test for Rainbow Six: Extraction and had no problems, so tried Metro: Exodus and it crashed

    Hey Guys,

    i have the same Issues after the latest windows updates - before i had no issues for about 3 months. With the latest Windows Update, my Monitors going dark and my graphic driver seems to crash. Now i have disabled fTPM in my bios, the error is gone, tho my graphic driver is still crashing, when iam playing games.

    Would you reccomend a fresh windows install?

    Best Marco

    Something is peculiar regarding this error. The Microsoft Root Authority certificate expired on 12/31/2020. Now, that may be all fine & well if the signing of certificates was performed prior to 12/31/2020. I note new Windows 11 certificates have expiration dates well into 2036. It more or less speaks to me somewhere there is a failure in the code used to navigate to the Microsoft Root Authority to gain a valid certificate via the directed path: "amd-keyid-578c545f796951421221a4a578acdb5f682f89c8.microsoftaik.azure.net". I mean, that path has to be the CA doesn't it? IOW, it has to be the root server for any Attestation to secure the PKI RSA keys used by the TPM chipset. It "appears" it's effecting AMD since AMD is the keyid it is looking to find. Does the Microsoft CA Root Server not have the key or is the Root Server incorrectly configured for AMD? AMD not provide the code to MS to provide RSA keys for the CA Root Server? Does this effect Intel chips, as well?
