No power to the stepper motors?

I had just finished a carve and was setting up for a second one when i noticed there was no power to the unit. I turned the power off and back on. The fan on the X-Carve comes on but the power lights do not, neither front or back. I have tested the power and have power to the top circuit board so its not the e-stop, also my computer is not recognizing the unit when the USB is plugged in. At my wits end to what it causing this. FYI, i have shut everything down and restarted everything several times and still nothing. Any help would be great!

Check the E-Stop.

I have checked the E-stop. I pulled the wiring harness on the top circuit board and I have power when the E-stop is disengaged. I’m at a total loss on what it could be.
