Hi sorry in advance if this turns out to be something simple but I keep getting the ez debug leds on my mobo for the cpu and ram to turn on and nothing gets displayed on my screen.

Specs
Cpu: AMD ryzen 5
Ram: Hp 8gb ddr4
Psu: cougar vtx
Cpu fan: raijintek leto

Can anybody help me? It's my first build and I really hope I didn't mess it up.
