Dimension 4400 computer not running

  1. I am currently troubleshooting a computer, trying to figure out the culprit of the problem. When I press the power button, it lights up amber color but there is no LED lights, nor is any of the case fans or power supply fans are running at all. Essentially the only thing I hear from the computer is a very low volume high pitch sound from the computer.

    Things I tried so far:
    Checking Power Cord
    Checking Power Outlet
    Checking LED (unconfirmed)
    Stripped components to bare minimum.

    Here is the website of the manual that I looked at


    I have a few suspicion of the problem but need to confirm it here. Anyone else have any inputs on this? Any questions will be answered as detailed as best to my knowledge. Thank you.

    Motherboard or power supply is bad I think
