you could try these step by step:

• Reset bios to default and make sure you could go to windows
• Disconnect from internet
• Uninstall the gpu driver using ddu (clean and do not restart)
• Uninstall all the processors on device manager (should be 24 on yours) like this:
  
  
• Restart pc to bios and update the bios (download the file, extract it, copy the folder you extracted to flash drive, plug the flash drive on top rear motherboard, and find bios flash menu and find the folder, and proceed flash the file, wait and let it restart), then go to bios after update and load default/optimized settings.
  
  
• boot up to windows and install the latest AMD Chipset driver, reboot, and go to power plan and choose amd ryzen balanced power plans. you may now connect to internet.
  
  
• Install the latest radeon driver.
  
  
• And check windows update (and optional updates) if there is any. install them all (and reboot if required).

*do this all offline until reboot after installing amd chipset driver, also you may reboot to bios after all of this to set the XMP and check if secure boot is on (and previous settings you did)

Also try to restore factory key on the bios, then reboot to bios again, and set the secure boot to standard, then save and exit.

make sure your ram is on slot 2 and 4. Download needed files (highlighted word) before doing step 1.



also make sure the psu connected to the gpu is 1 pcie cable per 1 slot (use main cable, not the branches/split) like this:
