Hey everyone, so ive built up my first PC, and i'm having an issue where my PC isn't Displaying any video when i turn it on and i can't really figure out why, i feel however my CPU May not be compatible with my Motherboard, but if anyone could help it would be highly appreciated.
SPEC: ASUS Prime B450M-K
AMD Ryzen 5 3400G APU
Team T-Force Dark 3000MHz (2x8GB) DDR4
Cooler Master MasterBox Lite 5 Mid Tower Case
CoolerMaster MasterWatt lite 600W PSU

Note that im planning on running Intergrated graphics until i can afford a Graphics card

Hi,
The CPU is supported, but with a BIOS update. What are the last 4 digits on a thin sticker on board?
