I have a new main board and Cooler Master case I’m setting up, for some reason when I plug in the power supply (100w), the led on that side lights up and it does the blinking led check. But no power is delivered to the expansion cards on the other side.

I tested the expansion cards and confirm they work on the side that has power. Is there any hard reset fix? I didn’t do anything but install a new SSD, it was working before. The minor annoyance is one of the ports is taken for powered but the other one is for my display so I can’t get into the BIOS as there’s no power to the keyboard on the other side.
