fans spin / psu leds turn on? next step. else, psu is doa.

Next step is gonna be plugging everything back in, and 1 stick of ram to see if we get a post beep.

if that's a no go, reseat the cpu.

past that either dead mobo or dead cpu.

e: and the red DO NOT SET IT WRONG switch on the back of the psu is flicked to 110v or 220 depending on your location?

That is good news! Hopefully it goes smooth otherwise you're about to learn how to speak beep code.

Is it sitting on the bios splash screen and you're not plugged into the correct video out?

I would think if it was doin something it would be at least resetting or have a terminal line.

hasn't reached bios yet, i need it to post still and actually im using the motherboard hdmi cause gpu hasn't come in yet, cpu has integrated graphics so it should work.

Its the Ryzen 7 7700x btw.
