Okey guys so I just set up my first build:
-msi X370 Gaming Pro
-Ryzen 5 2600
-Sapphire RX580 8GB Nitro+
-G.Skill Aegis DDR4 8Gb 2400 x1
-My old pc's Silent Storm 560W Semi Modular
- Kingston 240 gb SSD M.2 Nvme
- Old WD 750 gb 7200

I got everything into place, double checked every Power supply cable, put the ram stick in the right place recommended by msi, plugged in the dvi cable and nothing happened, the monitor shows no cable when off but no signal when turned on, so my guess is that's receiving some kind of signal. All the lights are working and the fans spinning, but as I don't have a speaker, I'm not really sure if it could be the motherboard, or even the ram, any guess?
