|You should always bench test a new system with the MBoard out of the case. |
You can set the motherboard on the anti-static bag it came in on top of the case on its side.
The only hardware needed are the following:
MBoard with CPU/HS/fan connected to the CPU fan header, 1 stick of RAM, on board or add in graphics, keyboard, monitor.
Connect the power supply 24 pin and CPU connectors to the MBoard. If using an add in graphics card that requires external power connectors then connect them. On board is preferable if available. Connect the monitor and keyboard. NO other cards, cables, USB, etc. No other case wiring should be connected at this time.
start the system by momentarily shorting the 2 power switch pins on the MBoard.
System should go through the POST screens and then show a screen stating there is no bootable device.
Before placing board back into the case be sure that there are standoffs mounted under EVERY screw hole in the board and ONLY under screw holes. If you have a cheap board with raised bosses instead of standoffs then you should be using insulating washers between the bosses and the board.
