I must not be the only one having this problem. There are many pages on the internet for this topic, but I couldn't find the solution. Note that I found mention of a problem recognized by AMD which should offer an update at the end of May 2022. Are you informed of this?


Thank you for your attention.

Best regards.

Some other reports I've read on the Internet indicate the problem arises after upgrading windows to a newer version and caused by previous drivers not working properly.


Did you just upgrade from Windows 10 to 11?  A new BIOS was released just last month but it was for ROM  family 87D6 and you have 8643.  I don't think it will work even though it's the same product ID.

Hello. Thank you for the answer. Actually my ROM ID is 8643 and my BIOS version is F41 (and now I understand why there are newer versions with smaller version numbers, and also why my attempt to upgrade to the new bios doesn't work not and was not accepted). Using HWInfo64 I saw that there was a driver test (with DriverFix). From the output of this software, only my Audio drivers seem outdated, but I checked on the HP site that I have the latest version. Finally (and really half-heartedly) I saw that there was a specific power management mode for the Ryzen (AMD Ryzen Balanced) which I selected. Since then, but it may be a coincidence, I no longer have any blocking (I remain skeptical about this potential solution, too simple, even if it is a driver - amdppm.sys - linked to the management of the diet which may be involved - to be continued...)

Of course, changing the power management mode does not solve the problem. For the moment I am testing AMD Software Driver Version 22.4.2 hoping that AMD has taken into account the problem of BSOD DPC_WATCHDOG_VIOLATION. To be continued...
