HP Envy x360 Ryzen F19 BIOS disaster DO NOT UPDATE

[mrami]

I have been contacted too to escalate the issue to HP support team, but still did not receive any feedback.

My ticket  with AMD, after many attempts (changing TDR_DELAY registry key and so on), ended with a "forward to the internal relevant team within AMD for further consideration to work with HP".

What's your bios and driver versions?

[mrami]

Windows 1809, F.20, I'm sticked to sp83831 (22.19.655.1) I have tried Andrenalin 19.1, 19.2 and 19.3, they all have the same problem: after boot, the system freezes for seconds. If after some seconds the screen flickers (see figure), then everything runs fine. If that weird 5 seconds flickering does not happen while the system is frozen, then a random BSOD between THREAD_STUCK_IN_DEVICE_DRIVER and  BSOD CLOCK_WATCHDOG_TIMEOUT is thrown.

Have you run HW Diagnostics (all) and reflashed the BIOS, same version?

Such problems usually indicate HW issue or BIOS corruption. My 3rd laptop had something alike (damaged graphics chip, overheating).

Did you try clean win10 install?

[mrami]

I have to re-run the HW diagnostics, that I run in the past having no issues, and I reflashed the BIOS. The weird flickering happens only with the latest drivers, with the older drivers I am having video artifacts with Netflix, Youtube, etc. but there are no strange flickering effects at boot.

I might try a clean install of Windows and a direct install of the 19.3.

When I first installed the new AMD official drivers I ran sfc /Scannow and it found corrupted files it could not fix, Even (DISM Deployment Image Servicing and Management) couldn't repair the files. I wiped the disk and reinstalled win 10 1809 and it fixed most of my problems.it would probably help your situtation......an d don't install any of HP stuff let Windows auto everything, then install the AMD drivers...  Good Luck.....

You seemed to have indicated issues during POST... if so HW or BIOS could be the culprit, if not it is Windows/display driver corruption.

Uninstall all AMD SW + DDU and install newest driver. If no help do the clean win install. Check your hardware but artifacts during video playback indicate the driver.

I have NO issues during POST. The issues I reported (as well as the video flickering photo shown) are only AFTER the video drivers have been loaded, right after login, when using 19.xx

No luck with DDU, as already reported. A full hardware test done overnight reports all ok. I have done a "Reset this PC" having no changes, but I suspect that the essential system regkeys and drivers are not affected during the "Reset", that is different from a fresh Windows 10 install, since the system came back with the same drivers as before reset but with all HP bloatware reinstalled.

When I have some time I'll make a clean install with an USB pen done with the Windows Create media tool (for Windows 10 1809).

I thought it was established that these fickering and BSOD problems are driver + BIOS issues? F20 has problems with Adrenaline 19. I'm on F19 and have the same issues with 22.19.655.1, but all fine with latest Adrenaline.

There are at least 2 ways to do reset (with, w/o files, with or w/o clean the drive...). Unfortunately even reset is in rare cases not a "cure all" solution. Your issues revolve around graphics (driver) or Win10 inability to manage hardware. Kill fastboot, hardware acceleration as discussed previously, troubleshoot in clean boot (driver, driver conflict etc.). Make sure Win10 works ok with Basic VGA driver, and only then update. If not, clean install Win10. With F20 BIOS do not use the old driver.

You need to simplify the environment and not do loops in already possibly corrupted one.
