I think my bios setting resets on each boot
1st boot of the day takes a longer time to start the pc
Next boot is easy but first boot takes too much time
Is there anything wrong with psu or motherboard?
I also experienced the same thing with my Asrock B450 Steel Legend. The BIOS is not resetting entirely. The CSM enables on its own when I boot after shutting down thus forcing the secure boot to disable.
