I think my motherboard is broken.

Built this pc 3 weeks ago. Brand new mobo. Cpu and gpu are second hand. Ram is brand new as well.
Went to redo the cable management and I reconnected the 24 pic connector only. I turned the pc on and my monitor displays no signal. But all fans and other components spin up/light up. The mother board led also turns on. I have tried changing the monitor. Running withought ram. Running with each stick in each slot.
Even then it does not post. Even withought cpu power cable it still powers on all of the fans.
Thanks in advance

could it possibly be the power supply? i have a spare working one that i am going to try tonight.
i also have a spare mobo but would prefer not to have to remove that and breadboard it.

specs
i5 7600k

can confirm it is motherboard. bread boarded with new ram, psu but same cpu and gpu. no boot. when i changed the mobo but kept every thing else the same it booted. hence must be mobo.
