Asus Motherboard with AMD 64 X2 chip not posting!

Threaded View

I recently purchased a barebones kit that included a M2N-MX SE Plus
motherboard with an AMD 64X2 CPU.
I put everything together but cannot get the computer to POST. the
motherboard has power, as does the heatsink fan and hard drive.
the keyboard lights flash when I first hit the power and the monitor
power LED turns green, but afterwards nothing happens.
I've re-seated the RAM as well as the CPU.  the lack of any audio
beeps tells me its CPU or motherboard related but naturally I don't
have a comaptible motherboard or CPU to do any
process of elimination testing.    Seeing its been a few years since
I've built a system wanted to check around though.  Any suggestions?
Oh, what I'd do to see the BIOS screen about now... ;-)

1) Make sure the ATX12V 2x2 power connector is connected. That
    feeds the processor.

2) Pull RAM and any add-in video card installed. The board has
    integrated video, and that cannot be removed. The purpose of
    this test, is to strip off any hardware that can "hold" the
    board in a silent state. If you can get the board to beep,
    you know you've got a processor reading BIOS firmware, and
    some probes of the chipset must be working, in order to
    generate the beeps.

3) While this isn't a likely cause, find the CPUSupport page on
    the Asus site, and compare the details of the processor you
    bought, to the release number of BIOS printed on the paper
    label on the BIOS chip. The BIOS chip doesn't always have
    a sticker, so I cannot guarantee you have all necessary info
    to determine there is a mismatch. Sometimes the problem will
    be a too-old BIOS version.

There will be some small percentage of motherboards that are DOA. Or
perhaps something changed when pressure was applied to the
board to install the processor or RAM etc. There are even
occasionally boards, where the components didn't all get a
thorough solder job, especially near the edges of the motherboard.

You can pull the board from the case, and try the "cardboard"
test. That eliminates a standoff in the wrong place, from
shorting to something on the bottom of the board. Standoffs
only go, where there are "plated rings" on the hole in the
motherboard. The "plated rings" are at ground potential,
and are intended to make electrical contact with the
standoffs. (Which is why the standoffs can be brass.)

In terms of processors, normally the dropout rate for processors
is pretty low. If the Newegg reviews number in the hundreds,
you may get a good idea how often a DOA processor is received
from AMD now.
