The problem is that Windows update has corrupted the install.
You will need to do a few things:
Disable Hibernation/Fast Startup
Download the latest AMD driver. You may already have that.
Download DDU from Wagnardsoft_com. Follow the instructions, must be run from safe mode with internet disable.
Install the AMD driver with internet still disabled. This keeps Windows update from messing things up again. Choose clean install if available. If not that it good too as DDU fully cleaned the old driver info out.
Restart and plug the internet back in.
I did as you said. I disabled hibernation then I went to run DDU. Once that was done, I went to install the AMD driver without internet. However, my computer still keeps automatically restarting when the driver is 37% installed. Once my computer starts turning back on, I see myself at the automatic repair screen again. I made sure I ran DDU in safe mode without internet and tried to install the driver without internet, but I still get the same problem.
All I know is that my computer experiences a system failure when the driver is 37% installed which is what causes the automatic restart.
I just tried 19.5.1 and that still causes a system failure.
As for the hibernation, I have disabled hibernation, but that still did not work. My power plan is also already on high performance.
It's not impossible you just have a card that went bad. If you have another computer I would try the card in it to see if it is the card or not. Unfortunately there are a lot of reports of cards going bad after the failed installs.
If your GPU is from sub vendor HP, then we might have had the same issue. I came to the conclusion that there is an issue with the stock BIOS for HP's AMD R9 390X causing the driver install to fail and the system to hang.
I have created a custom BIOS for the AMD R9 390X HP OEM. I used an XFX BIOS (XFX.R9390X.8192.150612.rom) and updated fan and other settings to be equal to the original HP one.
I have flashed it and the GPU is working fine now. AMD drivers were updated to the latest version "Win10-Radeon-Software-Adrenalin-2020-Edition-20.5.1-June10", 27.20.1017.1011.
