    I have my niece's desktop pc here which won't power on at all. No beeps, no cpu fan, no nothing, it's completely dead.

    I've tested the power supply and it's ok.
    I've checked and secured all cables/connections.
    I've tested the power off/on switch on the case and this is ok.
    There are no lights showing on the motherboard at all.
    The motherboard model is RC410-M rev:1.01

    Any ideas anyone?

    how have you tested all of the above?
    from what you've said, sounds like the motherboard is dead
    ..but im sure you already knew that

    Thx for replying so quickly m8.

    I tested using a voltmeter but also replaced power supply with a good known working one just to make sure.
    I took out a good off/on switch from another machine i have and used this too but still no joy.

    I was thinking it's either the motherboard too or cpu but is there a way to test either?

    E-machines.

    It's dead, and rightly so.

    Bloody things.

    Take out the HDD and slave it in a quality machine to get the data off it.

    Beat your customer until they understand that buying a PC from PC World/Dixons/Currys/Asda/Tesco is a BAD thing.

    Oh, and once you've retrieved the data from the old drive, chuck that over the fence too.

    I've stopped smoking, sorry if I sound grumpy, it's because I am. :x

    Emachines = poo

    THe power supplies used in systems like these are usually crap and when the power supply fails it tends to take something with it. YOu could be a conspiracy theorist and say its designed like that so you will pay extortiant amounts for emachines people to fix it.

    if you have tested everything like you said then I would suspect the psu has taken the motherboard with it when it died.

    Have a look on the mobo (you may need a torch) for burnt or scortched bits.

    Look at the capacitors (small cylindrical objects near the cpu socket) if any are leaking or collapsing on themselves or look like they are expanding then the motherboards had it.

    Put your nose next to psu fan can you smell burning or a burnt smell if this smell is anywhere else on the mobo then it's had it.

    suggest what was said above and if customer refuses kill him :)

    yep.

    I forgot to add try a cmos reset it could start things going however unlikely but worth a shot.
