Question pc build crash

New build up pc by myself.
Ryzen 3 2200g (
motherboard is AB350-DS3H ) with integrated graphics and 8g ram corsair vengence with a power supply of 450 watt bronze,mini rose-will case.
Its my first time building a pc so i checked twice everything and when i turn on the monitors, its show black and green screen :(
any ideas?
Do you know if that board was updated with a BIOS version compatible for a 2200G processor? By now most boards should have been updated before purchase...the box would say 'Ryzen 2000 Ready' on it. But it makes sense retailers would discount new-old stock like crazy to clear inventory before year-end to avoid taxes.
