New build has funky screen when starting up

https://ibb.co/YXdSQK0

Just built 2 computers yesterday. One for me and another for my friend. Mine is working perfectly and his was working at first after putting it together and throwing in the windows and drivers.

After he went home and started it up he started getting this screen. He apparently has some reset switch or whatever on top of his case and is able to hit it, it refreshes the screen and it goes away. Asked him to try using his MB instead of GPU but said his MB work at all so assuming his processor does not have on-board graphics.

Any ideas what could be causing this?
