Custom-built computer won't turn on

  1. I recently ordered the parts to build a computer and once I had everything hooked up I could not get the computer to start up.

    PC components:
    Raidmax Smilodon Tower with 500w PSU
    Asus P8H 61-MLE Series Motherboard
    Intel Core i3-2100 LGA1155 Processor
    G.Skill DDR3-1333 4GB (2x2GB) RAM
    Western Digital 320GB HDD

    The MoBo led comes on showing that the PSU is plugged in and on but no response when the PC switch is pressed. I've tried moving the MoBo jumper to reset the CMOS with no response yet.

    Also, when I unplug the ATX12V plug from the MoBo I get a light/fan response but still no boot...

    Any suggestions or help?
    Plz and Ty

    sounds like you may have the power and reset plugs in the wrong places read your manual and see where they need to be plugged

    Checked and double checked the powersw and resetsw but from what I can tell they are properly plugged into the motherboard

    I've read carefully through the motherboard manual several times with no success reconnecting cords to make sure they were tight and placed correctly. The Motherboard L.E.D. light is on but the system still does not boot when the power button is pushed.

    Make sure your ram is correctly seated. i.e. remove ram completely, then open latches and press ram firmly into the slot until you each lock snap into place.

    Tried reseating the RAM, no change...

    You got another computer you can use to test the PSU?

    Is the voltage selector switch set to the correct voltage?
