    Motherboard Problems *sigh*

    Well having added upgrades etc..
    My computer was working until I decided to open the case. <_<
    I ended up frying two motherboards blah blah.
    Now I have a problem with my 3rd new one.
    It's not fried for sure, I even thought it was faulty at first but the shop tested it for me and I ended up paying an extra 15 pounds.

    The motherboard I have is Abit I-n73h, I can boot up the system fine, the fans are moving etc...
    However there's no power going to the io panel, so no monitor, keyboard etc...
    First I thought it was the cpu but now I'm not sure!
    It's a Pentium D 925, might have fried it but I doubt it...
    I have 2xDDR2-533 Ram sticks corsair which are fine.
    That may be the problem actually but I hear no beeping at all literally.
    *sigh*

    No output on the screen?

    Normally a problem with the CPU
    do you get any beeps from the motherboard?

    I got no beep on my Abit FP-IN9 motherboard when it had faulty ram.

    Strip it down to bare bones, CPU, RAM and VGA; see what happens then.

    Still no joy, remove video card. Still no joy, remove ram. If there is STILL no beeping that only leaves CPU and motherboard.

    Out of both...I wouldn't know without putting in a good known component (ie CPU). It could also be that a power cable has been dislodged or even the PSU is on its last legs.

    are you sure you don't have a standoff in the wrong place, causing a short?

    ...or power supply. Do you have a spare power supply your could use to test?

    If it is booting (and you arecertain it is booting) then the CPU will OK. Powersupply is the next likely cause - are all the PSU connectors located correctly? (Especially auxiliary connectors)

    Normally a good PSU will shut down if there is a short on the system (wherever it occurs - so the fans wouldn't spin up.

    As previous poster said, strip down the computer to the basics - you might also want to consider building it outside the case (stand the mobo on a piece of card or hardboard) It is usually easy to do that and check all the connections are in place - if the system works then, you have

    a. reassured yourself that all is working
    b. know that there is something not right during the build, so you can double check at every step.
