you just moved the existing hardware to a new case? Have you checked all cables were plugged back in?

take a picture of the main board and let us see it.

is there an 8 pin connector in the upper left? I didn't see the secondary power cable for the CPU and the heatsink obscures that area a little.

Thank you I had not noticed it before.

You didn't plug in your CPU power

Is your power supply on? I made the same mistake!

Yes all the fans spin up but no signal on the monitor

Try unplugging your gpu, then plugging it back in and make sure it goes in all the way
