Question Ryzen 5 PRO 4650G and motherboard?

Jun 21, 2021
Hello everyone,
I was building a new PC with MSI b450 tomahawk max and Ryzen 5 4650g in the first time I powred the pc the Mobo ez debug led with indicate to the CPU and nothing with showing in the monitor but after a bios update it worked and the mobo detected the CPU and the CPU specifications right but it was indicating to the CPU in the ez debug led but I was working and i started installing windows but the power suddenly went off during the installation and i had a tough time trying to start installing it again (i was constantly turning off the pc to start a new instalation ) however one time when turning on it again there was nothing showing as well on the monitor and the keyboard wasn't working so
is it a motherboard compatibility problem (though the motherboard manufacture was saying that it support Ryzen 4000 series APUs ) or what ?
