Question Integrated graphics, no display first boot

[Orthasthemighty]

Hey all
Just built a new system and for some reason every time I start my PC for the first time everyday I get no display, but will work after I reset. I thought it was a motherboard issue so I got it replaced but the issue still persists. It's a i7 8700k stock. Have tried numerous things. I guess it's not a huge issue but would rather not have to restart every time I want to use it. I am unable to try it with a GPU at this stage. Anyone have any ideas what the problem may be???
Thanks
Orthas

It might be that the PSU cannot give enough power. Does it have any labels on that you can take photos of so that someone can identify whether or not if is good enough?
