Ok. So all it was was just a ram stick not fully seated. I'm dumb

The CPU power has an 8 pin and a 4 pin right next to each other. I only have the 8 pin installed (it didn't come with a 4 pin connector that I saw)

And I'm aware the cpu fan is sideways

I removed the graphics card for the latter ones for better view.

Won't let me upload pics.

Yeah, I have tried both the hdmi and dvi. It's the same monitor my old pc worked with.

Working on a ground up build, I have everything connected to the best of my knowledge. PC powers up, all fans running, but no display to the monitor and no USBs seem to be working. Keyboard plugged in ...
