    I just installed the board, antec 430w power supply. Come up with the post
    process and then turns off. I cant get it to stay on for more than 6
    seconds. Please, any ideas on this?

    Intel 3ghz 800mhz FSB CPU
    2gb corsair 3500c2 ram 4x512

    Thanks for any help!

    My intel 875 board does this too, but only when the rocker switch on the
    power supply has been turned off. Does the board continue to turn itself
    off even after you push the momentary switch on the front panel?

    A couple f other possibilities:

    1. CPU Fan is a slow speed one and the BIOS is shutting the board down to
    protect the CPU (try turning off the fan monitoring in BIOS temporarily)
    2. CPU fan plugged into the wrong header

    Have you tinkered with the memory timings to push it up towards the corsair
    rated speed?

    If so, then clear the cmos and start again, but this time leave the CAS at
    2.5 - until you have time at hand...
    Note that as you have 4 x modules, memory timing is more critical and CAS
    often needs to be increased as more memory sticks are added. Something to do
    with fan out.

    Failing that, if the problem is in the BIOS / fan / power, you may need to
    clear the cmos to get it up again to clear it. This is usually in the m/b

    I cant get into the BIOS because the system shuts down after 6 seconds :

    Is it doing the memory count? Try removing 1gig out.
    Good Luck.

    Could also be a heat issue - make sure your heatsink is making good
    contact with the CPU. Also make sure that both motherboard power
    connectors are secure.

    Double check that your ATX power switch jumper 2-Pin Pwrbtn (case front
    panel bundle to connector on mobo) is on the correct pin and is oriented
    correctly (pwr/grnd).

    The polarity of LEDs is important. It's not supposed to matter which
    way the connector you're talking about is plugged in.

    Considering I use a screwdriver (no case) I shoulda realized that mistake
    prior to posting <sheepish grin>
