    Tony have you tried taking the case off and reseating the cables and cards?

    Also can you get a BIOS screen? Do you ever see any info displayed, such as what key to press to enter Setup?

    If it's an older system you might want to replace the cmos battery on the motherboard. It can also help to use the shorting jumper usually found next to it to reset the cmos. Just change the position for few seconds.

    Hi adt048

    Sounds to me like your power supply unit has died - do as Rog says and take the cover off, check for loose connections and make sure everything is seated ok

    Make sure the power is off when you do this - and touch the case to discharge any static before touching anything

    Then wait for another opinion from someone in this forum

    Is your monitor light green?

    If it's orange your graphics are the likely culprit.

    It could be either the power supply or a bad motherboard. Does the fan come on and get up to speed right away? Does it appear to slow down when the drive kicks in?

    You could try swapping in the power supply from another system to test. But don't do it the other way around (test a suspected bad one on a good system)

    You mean it works with a known good power supply? Then your motherboard is fine, it's the old power supply that's shot.

    I presume it's the new computer you are having trouble with ?

    This sounds like you took the suspect power supply from your new computer and put it in your old computer - and the old computer worked ok

    If this is right, then you are lucky the power supply was ok , or you could have damaged your old computer

    This means it is not the power supply but the motherboard you need to look at

    As Rollin' Rog and I both read your answer differently - you need to clarify exactly what you did

    Ok, well that was the reverse of the test procedure I wanted you to run. It's not really a good idea to take a suspected bad power supply and put it in a good system. If the power supply is really bad it could have damaged the good system.

    But yes, at this point it sounds like there is nothing left but the motherboard.

    If you haven't removed and reseated the ram, you might as well try that.

    You could try gently removing and reseating the cpu itself. Do make sure all power is off and your hands have been grounded before handling it. And be very careful about not bending the pins. This is kind of a last resort test. I'd also tell you to remove and reseat the cmos - rom chip if I knew how to tell you to find it.

    The cpu chip would be under the heat sink.
