    your PSU & maybe the mobo, grafx and / or CPU may have died if your not using a surge protector, if you are using a surge protector it may just need reseting or replacing (depending on the type)
    BTW try a working power cable

    more than likely you have a fried power supply,You are going to need another
    power supply... and make sure you get a surge protector...

    Might as well try an ATX reset first before you spend your dosh on a component.

    Take the power lead out, hold the power button on the front of your tower for about 25 seconds, put the power lead back in and see if it works. 25% of "No Power" problems at my workplace are solved by that. It's quick and easy and worth a try really :)

    Just plug the PSU into another computer. If it doesn't work then your PSU is fried (bad) and if it does work then your components are fried (really bad).

    You can also buy PSU testers which have an LED for each power wire which light up indicating that you're either getting or not getting juice from it.

    I was going for a zero cost solution but yes, that will work too.

    Either just the PSU has been fried, or the whole system has too because i would of thought if the whole system got fried then the PSU would of too.

    [ot] Don't you think that in this day and age, PSU manufacturers should sell the PSU with a small device, indicator, to help ascertain quickly whether there is any juice coming out of the PSU? All they really need is a a light bulb at the end os some male plug of some description. It's not like they have not got the materials.... [/ot]

    From my experience, if a PSU or mobo die, there is some activity like fans spinning etc. From the description it sounds like a 'door-nail-dead' PSU. Have a simple inspection of the mobo to check for electrical burning marks (metallic shiny bluey colour) on the back of the mobo.
