If I use the AMD Ryzen Master program or bios to adjust the GPU core clock to any setting besides the default it works fine except when I reboot the computer then the computer shuts off. Trying to start the computer it will not start. I have to clear the bios on the motherboard and then the computer will start and I have to setup the bios every time. If I overclock the CPU and/or memory from the bios or Ryzen master program then the computer works as expected. Overclock works and I can reboot the computer. It's only if I change the GPU core clock in bios or Ryzen master that the computer shuts off on every reboot. Besides the issue with the GPU the system runs nice, quiet and cool.
