  1. are all the cables plugged in?

    you should have 2x 6 pin PCIe cables for the graphics card, 1x 4/8 pin ATX12V cable and 24 pin motherboard cable along with the molex, fan and sata cables where they're needed.
  2. maybe you should try turning on the power without the swtich, meaning using tweasers.

    or maybe it could be just when you first connect and turn everything on and that's how your motherboard or psu loads up.

    see most people once they connected everything they leave it and don't disconnect.
