New build problem with asus p4p800

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

I'm building a new machine with the following specs:

Asus p4p800
2.8c cpu
200 gig hd
512mb ddr pc3200
Radeon 9800 pro
Analog 17" monitor

I installed everything and the PC will power up but no video. The
fans will run and power seems to be going, but nothing comes on the
monitor. I put the new video card in my old machine and the card
seems to work fine, ruling that out. That pc will boot up and show me
on the same monitor. On the new machine I have the 4 pin plugged in
and the 20 pin plugged in, but am I missing something? Or did I get
some defective hardware or mess it up myself?

Thanks for any input.

    I have a similar system, except for the monitor and deluxe version of the board.
    No problem to get the vieo here; Except that I did not even try to boot first once
    installed..

    First thing I did was to Clear the CMOS... Maybe I avoided problems ?
    Did you try.
    I presume you have hooked the Added Radeon9800 Power connector.
    Check that too.

    For a power supply, the +12V should be rated for 12A to 15A, to
    work well with the board and video card you've got. The 15A rating
    gives you a little breathing room. Check the label on the power
    supply for details.

    Depending on the exact motherboard model number, the board may
    have a Voice POST feature. If it does, connecting an amplified speaker
    to the lime colored, Lineout connector on the back of the computer,
    as that could give you a voice message as to what is wrong. Voice
    POST tends to be a feature of "Deluxe" boards.

    Otherwise, you can listen for BIOS beep codes, to try to figure out
    what is wrong. Older versions of the BIOS would beep once for every
    USB device, while recent versions of the BIOS had beeping disabled -
    I hope in an error situation, the board can still beep an error
    code for you.

    I like the suggestion of trying the "clear the CMOS" procedure.
    The only warning about that I would give, is to make sure the
    computer is unplugged, before following the procedure listed in
    the manual. You don't want any +5VSB on the motherboard, while
    using the CLRTC jumper.

    If you run out of things to try, do the "cardboard test". I
    do this anyway, even if there isn't trouble. Place the new
    motherboard on your tabletop, with a piece of cardboard underneath
    it. This prevents shorting to any conductor underneath the
    motherboard. Plug your components in and experiment with the
    motherboard outside the case. It is a lot easier to see what
    is going on this way. The PSU can be removed from the case via
    four screws in the back of the case. Some motherboard installs
    are upset, by the use of an extra standoff touching a copper
    conductor on the bottom of the board. Standoffs should only be
    placed where they line up with plated holes in the motherboard.

    Very little is needed to see a response from the motherboard.
    CPU, memory, video card, motherboard, PSU, and something to
    momentarily short together the power switch pins on the PANEL
    header, should be enough. You can add disk cabling, once you
    see the BIOS screen show up.

    Make sure the 4 pin and 20 pin are firmly plugged into the board.
    Your symptoms almost suggest the 4 pin isn't installed. The fans
    can run, because the single +12V wire on the 20 pin connector is
    used to power the fans via motherboard headers. But the 4 pin
    connector is the exclusive source of power for the CPU. Without
    it, the CPU cannot run.

    When pressing and plugging stuff into the motherboard, make sure
    it is supported underneath at all times, so the board is not
    flexed excessively by the insertion force. That requirement
    is a little tougher to meet while doing the "cardboard test".
    Flexing of the board is not good for large BGA devices, like
    the Northbridge and Southbridge, as it can break the solder
    joints.

    HTH,
    Paul

    Whats the voltage of that Radeon 9800 Pro??

    The voltage MUST be 1.5 NOT 3.3 v

    As 3.3 isnt supported.

    Just had same problem

    It was the ram!

    Try a different stick.....if not then maybe that board doesnt like that vga
    card...I`ve had that too where a card just wont work in a certain board but
    will in others no problem!
