|If you just installed that motherboard into your case you should have bench tested it first. |
Is the board new or used?
Are you sure the CPU you installed is compatible?
Do you have the Auxiliary power connector plugged in directly to the board?
None of the case to board wiring is needed to run the board.
Simply shorting out the two PWR pins should start the board without any wiring connected to THAT header.
Supply the model of your processor, RAM and the model number of your power supply.
