AMDKMDAP - Device not started






This problem has been persistent for about 3 months now and I have tried multiple solutions I found online to no success.

The problem started after I installed a M.2 Nvme in December last year.

I have tried the following:

  • Clean windows install on M.2
  • Clean windows install on previous boot drive
  • Driver roll-back to multiple old driver versions
  • DDU clean up
  • AMD utility clean up
  • sfc /Scannow
  • Device reinstall
  • Device lane change
  • Bios update
  • Replaced MUI file

My hardware is:

  • MB: MSI B550-a pro
  • CPU: Ryzen 5 3600
  • GPU: RX 570 4G
  • Boot Drive: Aorus M.2 PCI-E 4.0 500gb
  • RAM: 16gb 3200Mhz

I really am just lost now as to what could be causing the problem. If there is anything else I can try please advise.

Willing to provide any more information that is required.

Please please please help
