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.
