Question Problem trying to install windows freezes after logo with light blue screen

Aug 31, 2019
As it says above, new build. I've taken it to one stick of ram, no graphics card etc just mobo, cpu + fan,the USB installing windows and an ssd

Basically I can browse the bios etc fine but as soon as I try and install Windows from the USB it goes past the windows logo then just stays on a light blue screen with no text.

Specs are
I7 9700k
Corsaair vengeance 3200mhz ram
Gigabyte z390 aorus pro

I've tried googling and searching around but I kept finding people talking about blue screen of death etc and this is just a light blue screen. Any ideas? And thanks. Sorry if I haven't provided enough info let me know and I'll add more.
