The Gigabyte RX 460 super oc x8 doesn't need a PCIE power connector, right?

Having tested with another card and getting the same result the board might need a BIOS update.

Not sure if you can do that easily without a display output.

Edit: Anyway do not attemp a BIOS update if you're not familiar with the process as if the update process goes wrong you might end up bricking your board.

Are the mouse and keyboard PS/2 or USB?

If USB, were the mouse and keyboard plugged into the motherboard I/O panel on the back or to front case USB connectors?

If so the front case USB connector/ports might have a short.
