    What are the complete specs of this computer including PSU model/make etc.?

    Do you hear any beeps?

    Please ensure that there is no dust inside the casing, if you haven't cleaned it in a while do so by using compressed air. Also check that all cables are correctly attached, and RAM is seated properly.

    Disconnect everything from the motherboard, HDDs/DVDs etc. and see whether the system POST

    No beeps, may mean that your motherboard is not responding. But before going any further, I'd suggest that if you can get another PSU try booting this system with it.

    I hope someone else will also look into this thread, and may come up with some more info.

    i tried a different psu but it was a 250w power supply should i go buy a higher watt on also if i found the voltage switch got changed and it stayed on when the power switch was hit

    250W should let you boot that system IMO.

    Can you please download CPUz, run it, then go to About tab and click on "Save as Text", once you've done that, attach the resulting file with your next post.

    Ensure that the motherboard is not shorting or something like that.

    If that is not the case, well then you probably have dead/malfunctioning motherboard.

    Hmm ......... may be the switch is broken or something? because as you said, when you short the power connector pins it POST (correct me if I am wrong) ....... I don't know if you can get that button repaired or not.

    I'm sorry, I am unable to clearly understand what do you mean.

    If nothing comes up on screen, it means it probably isn't completing POST, which doesn't sound good frankly.

    I'm still suspecting motherboard here, try booting it with one RAM stick (in case you have multiple RAM modules) and disconnect all HDDs/DVDs etc., I think we tried it before but there is no harm trying again before you make the decision to buy new motherboard.

    I am afraid you can't install windows without a key, if you have some valid record of your OS purchase you may contact MS and see whether they can help you in this regard. Otherwise, your only option will to be buy another one.
