New motherboard that does not post

I recently bought these items from Newegg:

MB ASUS | M5A88-V EVO 880G RT

CPU AMD|4-CORE FX-4100 3.6G 8M R

And this from Crucial Technology:

CT2KIT51272BA1339 8GB Kit (4GBx2), 240-pin DIMM

When I put it together, it did not post. It has NEVER posted. When
I press the power button, the CPU fan and case LED come on but I get
no display on the monitor and no beeps. I connected the monitor
cable to a laptop computer and got a display so it cannot be a bad
monitor or cable.

I tried it with two new power supplies. I tried it with two memory
modules, one memory module and no memory modules. If I hold down
the power button for four seconds when it is on, it turns off.

I took out the CMOS battery and left the jumper in the reset
position for more than 15 minutes but it still did not post.

Does anyone have an suggestions as to what I can do to get this
motherboard to post of how I can determine what is wrong? Thank you
in advance for all replies.

After I kick it, he will sometimes play with it for a few
seconds to several minutes. His favorite are the ones that
rattle. He'll play with any ball that makes noise.

You forgot to connect the ATX12V cable.

No. I connected that cable with both power supplies but that was a
good guess. I really appreciate your time and effort in trying to
help me.

"MB ASUS | M5A88-V EVO 880G RT

CPU AMD|4-CORE FX-4100 3.6G 8M R"

OK, let's check the BIOS compatibility.

http://support.asus.com/Cpusupport/L...20EVO&p=1&s=24

FX-4100(FD4100WMW4KGU),3.6GHz,4C,95W,rev.B2G,AM3+ ALL 0707

The FX-4100 requires a minimum BIOS version of 0707. If you have
another processor chip to work with, you could work at verifying
the version present now. Or, if you know you've flashed the BIOS,
you may have some record of what version you flashed with.

If the motherboard is brand new and untouched with regard to
flashing, you can look for a paper sticker on the flash chip,
and see whether it is version 0707 or later. If the revision
is an older one, you may need to borrow an older processor,
to do the flash upgrade with.

If you connect the computer case speaker to the SPKR header,
remove all RAM, then there should be a RAM error (beep) code if
the processor is actually able to execute the BIOS. If the
case speaker remains silent, while doing the "missing RAM test",
then the BIOS revision may be too old to recognize the processor.
The speaker can only beep, if the processor can run code, and
pulling all the RAM, is a way to trick it into beeping the speaker.
But that only happens, if the processor is able to execute the
BIOS code.

Have you tried hitting the reset button or blipping the reset pins on the motherboard? Sometimes doing that every 10 seconds will eventually make the computer boot.

Are there any shorts between the motherboard and case? They usually occur around the mounting holes (check each, top & bottom) or at an unsupported corner (no standoff within 2"). Also extra standoffs that don't line up with any motherboard holes can cause shorts.

Do you have a speaker connected to the motherboard pins? It can sometimes give diagnostic beeps even when there are no other signs of life.

Is the CPU heatsink installed properly and making contact all along the top of the CPU package? Some motherboard BIOSes won't allow operation if the CPU overheats, despite all modern CPUs having built-in heatproof protection.. Some do also do this if the fan doesn't detect spin (fan may spin but motherboard doesn't see any RPM pulses from it).

I normally test a new motherboard by installing just the bare minimum amount of hardware so I can see if it works -- CPU, CPU heatsink/fan, one memory module, speaker, power button, reset button, keyboard, monitor, and video. I run a memory test for a while before installing anything else.

The only sticker I see is this one:

There are two instances of the letter "O" that are filled in and
then this number:

O 0C1G023-01197-MB07N0-A03 0903

I think I have version 0903, which should be later than 0707.

If you are getting no post beeps and no display it is likly a faulty
proccessor?.

how many watts is the PSU?

The first one I tried was a Thermaltake 775 watts. The second one
was a Corsair 600 watts. The manual recommends a minimum of 450
watts. I was using the on-board video and had no drives connected.

I just tried that for more than six minutes but the motherboard did
not post.

I do not think so.

They usually
occur around the mounting holes (check each, top & bottom) or at an
unsupported corner (no standoff within 2"). Also extra standoffs
that don't line up with any motherboard holes can cause shorts.

There are no extra standoffs. The motherboard has nine mounting
holes. All nine mounting holes have screws in them that are screwed
into standoffs.


Do you have a speaker connected to the motherboard pins? It can sometimes give diagnostic beeps even when there are no other signs of life.

I have a speaker connected. I used an ohm meter to check the
speaker and speaker cable. I measured 17 ohms at the motherboard
connector. Can a speaker fail and still measure 17 ohms?

Is the CPU heatsink installed properly and making contact all
along the top of the CPU package?

I think it is. The OEM heatsink has a clamp with a lever that
pushes the heatsink down with a lot of force.

Some motherboard BIOSes
won't allow operation if the CPU overheats, despite all modern
CPUs having built-in heatproof protection. Some do also do
this if the fan doesn't detect spin (fan may spin but
motherboard doesn't see any RPM pulses from it).

The fan is plugged into the motherboard. The fan does spin. How
can I tell if the fan is generating rpm signals? (I do not have an
oscilloscope.)

If the motherboard will not allow operation because it senses that
the CPU is overheating or that the cup fan is not spinning, would it
leave the power supply on?

This usually requires a visual inspection by removing the motherboard. If you test the motherboard outside the case, be sure to do it on an anti-static, non-metallic surface, such as the foam sheet that was inside the anti-static bag with the motherboard. Plain wood is usually OK, as is a 1/2" thick layer of newsprint or brown paper bags (no shiney paper).

There are no extra standoffs. The motherboard has nine mounting
holes. All nine mounting holes have screws in them that are screwed
into standoffs.

How about the corners? Motherboards and cases can flex a surprising amount or be warped.

I have a speaker connected. I used an ohm meter to check the
speaker and speaker cable. I measured 17 ohms at the motherboard
connector. Can a speaker fail and still measure 17 ohms?

I don't know what the motherboard's speaker connector is supposed to measure, but speakers and their wiring commonly measure 8-32 ohms. I think you should hear a click or scratchy sound when measuring the speaker.

The fan is plugged into the motherboard. The fan does spin. How
can I tell if the fan is generating rpm signals? (I do not have an
oscilloscope.)

Some multimeters have a frequency (Hz) function that can measure the pulse, but in practice, that pulse is always there unless its wire is broken.

If the motherboard will not allow operation because it senses that
the CPU is overheating or that the cup fan is not spinning, would it
leave the power supply on?

Good point. I don't think so. Also a short between the motherboard and case usually results in the power turning off in a few seconds.

I have a feeling NewEgg sent you a dud motherboard. A lot of times they'll pay for return shipping if you phone them rather than use e-mail or their online RMA form.
