  1. I have an ECS Elitegroup motherboard, pentium 4 sometimes boots,and
    sometimes just a black screen, If boot fails and I just leave it plugged in
    for a while it sometimes boots than crashes after a few minutes. anyone know
    what causes this?

    Might be bad/leaky caps on the motherboard..

    I had this guy fix my epox board about 3 months ago for the same problem

    It works great..
  3. All the caps look fine (no leaking ,no bulges) could they still be bad?

    Hi Ricki,

    If the board is still under warranty I would
    just RMA it. If the replacement works fine then
    problem solved. If not then it's time to ask
    around here for some ideas.

    Could be a faulty PSU

    hi Ricki

    from experience, some boards have that kind of problem due to faulty
    bios issues/memory problems and the like. I would suggest that you try
    to do a good cleaning of the board along with the memory and ram. I
    would also suggest that you try flashing the bios to a more recent
    version so that it will eliminate buggy irq handling problems. :)

    sometimes you can weed out the faulty caps
    by looking in where things get hot around
    these caps such as voltage reg's on your
    i replaced 2 caps in a p2-266 the other day
    2 1000uf 10 volt neer the voltage reg's, due to
    heat from them, the caps were leaky and upsetting
    the voltage rails, the system will not boot.

    Usually they're bulging too, there was a large batch of capacitors made with
    defective electrolyte that found their way into all sorts of things for a
    few years there, seems to be all over with now though.
