    I have tried with or without the video card, the red led still would not come on.
    Also tried with another video card but still nothing.
    The only time the red led lights is when I bypass the green wire on the power supply and the supplies then switch on but still the front panel would not keep lit and no tone from speaker.
    Do you think I can test the video card on a pc instead just to try it out?
    Thanks

    Update.
    Tested mac with another video card but still nothing and I it works on another pc.
    I think I should hear a beep if no video card is present. If no ram is present it should beep as well.

    The motherboard may be dead. Especially with trying a new video card and removing the ram, and still having no improvement.

    Yes I am thinking it may be partially dead, not sure about the processor though. The thing that it does not start on its own with just the power button already shows me that something is wrong with the board. Are there any tests I can do to check the processor is ok because if both are dead, it is surely not worth repairing?

    You most likely have a dead motherboard. Or it could be a power supply issue, you never know. I assume if you are confident in replacing capacitors, you can use a multi meter.

    Try this:

    I know how to use a multimeter. I know for sure that the power supply is 100% ok. But you can only check capacitors for short circuit on board, you cannot test for leaky capacitors on board.
    I think I am going to have a go at changing the capacitors on board since many of you are talking about them and though I am not seeing any signs of bulged capacitors or shorted ones.
    Will try to make some time to replace some of the capacitors.
