Null boot with GA-7n400 Pro2 rev 1, no beep codes

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

The system is failing to POST, though the fans and HDs do spin up
properly. Memory LED is lit as normal. No image on the monitor, no
beep codes at all. System speaker is plugged in and seated properly.
Have attempted booting without RAM, without HDs, without VGA card,
etc. and still no error codes or anything more than spinning of fans.
Have attempted to switch out power supplies as well, same results.


Athlon XP Barton 400FSB 3200+ processor with Thermaltake Silent Boost
heat sink and Arctic Silver 5. Processor is confirmed to work in
other system. Just in case though, I have also tried using a Barton
333 2600+ which also works in the other system.

Tried both a MSI GeForce4 Ti4600, and a NVidia GeForce2 Pro 64. Both
of these cards are confirmed to work properly in other system.

Have used various flavors of RAM, all of which have been found to work
on another system, no difference.

Have already attempted to clear CMOS by removing the battery for up to
several hours, doesn't seem to have any effect.

Any help would be appreciated, thank you for your time and effort.

    Did you plug in the 4 pin 12V connector on the mobo? It's on the upper left
    corner. The board comes with an adapter in case your PSU doesn't have one.

    Whoops!! Mine is Rev.2. Not sure if the both have that connector.

    Yes, the four-pin power coupler is properly seated and has been
    through this entire process.

    I also forgot to mention that none of the capacitors seem to be
    "bleeding" or otherwise damaged, but one close to the heat sink
    footprint seems bent at a slight angle to the board. Possibly it was
    pushed aside while installing the heat sink, but it doesn't seem to be
    bad enough to affect its function.

    I noticed that tight spot too. Took the heat sink and filed a little off the
    corner, now it doesn't touch. I had read in the manual that it cannot boot
    without that 12 V hookup. The only thing I can think of is the video card
    and you seem to be OK on that. As far as I know they are both AGP 8X, 1.5V.
    Good luck

    Try clearing the CMOS again by removing the battery AND unplug the power
    from the power supply.

    I've already wiped the CMOS several times by allowing the charge to
    bleed off like that, and it hasn't helped.

    I've basically concluded that the MB is dead and I'm now trying to
    find the warrantee information for it to see if I can have it
    replaced. Newegg's terms of return have already expired, but if
    Gigabyte offers three-year terms by default then I should be able to
    get another one.

    Oddly enough, something very similar happened to me before with a
    Gigabyte board several generations of boards ago. From this and
    other reports I would be led to conclude that MB death like this
    happens disproportionately often with Gigabyte boards; am I
    justified in starting to believe this?

    Is there a list of supposedly compatible memory for this board? I
    suppose that's a lot to ask...

    Also, the fact that the board throws no error beeps when attempting to
    boot without RAM suggests it's a problem with the board's other
    functioning, doesn't it?

    Sounds like the motherboard doesn't like any of the memory you're trying to use.
    If you still have the same problem if/when you get the replacement motherboard, try getting some memory you know is fully compatible.

    it's easy to check if it's purely the memory causing the problem with the
    board not booting up .... simply remove all of the memory ... if that's the
    problem area then you'll get error beeps indicating the memory is missing.
  10. 5 years later.... To anyone who reads this looking for a solution to the same proble, his computer seemed to start fine, but no video... tried different cards, all components worked on other systems. He was using agp cards-and since his ram led's were fine and no beeps, this leaves his GPU... I am going to guess that the heatsink was next to the capacitor he bumped, and it was not flat on the graphics processor. It will run fine for a short while after the install, then nothing... ever again. weird problem, no one ever figures it out. Try a PCI video card if you have one and I will guarantee it works.
  11. the above and below is not the case as I have 3 of these boards and they all have done the same thing BUT my the last board that died being my main machine just died quickly but defor that it use to lossing the memorry wile running and I just use to reseat it and go again for seconds or days then it just died so I think it a south bridge/chip problem as to the fault in design to heat sinck being turned 90 degress

    WOULD love to find out the problem and how to fix as I love the board

  12. Now ya see here son, this is what we call a dead thread, it died as no one was interested or no one had info for it, or the author found the info and decided to let the thread die.

    So we buried it, gave it a funeral and let it lie in peace.

    Now what ya have done here is Necrothreaded it back into the living realm, disturbing its grave and its peace! Why boy, why? The poor thread has suffered enough! Let it rest!!
