My b450-f has onboard RGB, and when I shut my pc off, the RGB stays on. I have the option in bios to change it so that onboard leds will shutoff when pc is shutoff or in hibernate, and when I set that setting to enabled, exit bios with saving, then turn my pc off, it works. When I turn my pc back on, then turn it back off, the setting resets back to disabled. Any fixes?
Already tried removing/replacing CMOS
