Question B350 bios issue

[Edragal]

Hello guys! I'm new to the forum, but I really need help. So I got a MSI B350 PC Mate that I wanted to use a Ryzen 5 3600 with. I updated the Bios with the recommended one from MSI, but it didn't work. The problem is that now the PC won't display anything with the CPU I was using before (AMD a8-9600) nor with the Ryzen 5. With the Original CPU all fans turn and the CPU light turns on, and with the Ryzen 5 all fans spin but there's no lights that torn on on the motherboard. Any ideas on what the issue might be?
