My PC was working well. Turned it off and later tried to turn it on and have no display or signal to mouse or keyboard. Can I enable a led or beep for knowing where the error is occurring? What else can be done for fixing it? All components are Ryzen 5600G, Vengeance ddr4 16GB, Samsung SSD 1T and Thermaltake 500W

Is anything happening at all? Is the CPU fan spinning?
If nothing is happening, it could be the power supply.

LEDs of the MB and case are working, also the case and CPU fan spins. Tried with a different PSU and got same result. Also reset the CPU o change the RAM to different slots but still the same. Also I did the CMOS shortcut with the pins but still the same. Anything else I can do? Start thinking is something wrong with the MB

Purely based on it being B450m, I'm wondering if it's a fairly old setup.
Have you checked the RTC battery? They do eventually deplete. Based on my experience, they last 2-10 years (totally depending on power-on time, etc.).
If the battery is low (under 2.8V open circuit), replace it, do CMOS reset, and give it a few minutes.
