Computer Build - no display

[Chrkeller]

I built a computer recently; I have everything installed except the GPU.  However, my CPU should have integrated graphics.  The computer turns on, the fans turn on, but I am not getting any display output.  I know the HDMI cable and monitor are in working order.  I also noticed the CPU fan is not turning on.  I do have two CPU power connectors running to my modular PSU.  Any thoughts?  I am a bit lost on this one, plus a bit worried.  CPU not working?  MB Bios needs to be updated?  I have DDR5 ram, which my MB should support easily enough.
