I bought this build: ryzen 5 2600, gigabyte b450m ds3h, vengeance lpx 2x8gb 2400Mhz ram, 550w bronze 80+ psu but when I turn it on the fans spin but nothing shows up on the monitor and I already tested the monitor and it works. the mobo’s light up pattern only lights out on the far left does this mean there’s a problem with the mobo or is the ram not compatible or something else. Plz help
