Brand new M2n SLI Deluxe Won't POST

was having Tons of trouble with my Old board (received a second
defective board back from ASUS so I decided to just get a new
board...SO...i got a M2N SLI Deluxe....Got it...tried a PCI Graphics
card I had but it wouldn't work so I figured I needed a PCI express
which i ordered and received today...also ordered and received some new
Corsair XMS2 SLI2 Ready Memory which Corsair said would be a good fit
for the board so everything should be just right....put it all together
today...and whala....nothing.....powered it all up...got a beep and the
thing just sits there....I've spent some $400 on all of this in order to
get this ASUS stuff working and I'm about to swear off of it
all...getting pretty fed up with it to be honest...two boards with
internal video problems and then this board that won't even POST....I
believe I set everything up according to their specs in the
manual...I've been over it all a couple of times just to make
sure...it's not like this is the first computer I've ever built but I
just wanted to make sure....

Any ideas on anything I should check...I've reseated everything a few
times...I unplugged the SATA hard drive to try and boot without it to
see if that made a difference, etc...

The fact that you got a single beep, tells me the ATX12V and main ATX power
plugs are connected. You wouldn't get the beep, if there was a problem
with the video or the memory. Otherwise, you'd get a beep code for either
missing memory or a beep code for missing video.

So, start with processor and motherboard. With no memory or video, you
should hear a complaint about missing memory (a different beep code).
Install the memory. You can install just one stick if you want.
The beep code should change to missing video, when some working
memory is present. Now install the video card. Make sure that if the
video card has an auxiliary power connector, that you've connected that
as well. And each time, when working inside the computer, unplug it, so
that there is no +5VSB present (at least make sure the green LED on
the motherboard is not lit, while adding or removing components).

Once the video card is present, the missing video beep pattern should
go away, and you should hear one beep (the short one, meaning it is
going to POST). If there is an error condition now, it should show up
on the display.

The PCI Express card has several connectors on it. I would try to
connect an analog (VGA) display first. If the PCI Express video card
has nothing but DVI connectors, I'd use a DVI-I to VGA adapter
dongle, then plug in the analog monitor. The reason I suggest this,
is the odds are best with analog. There are occasional problems
getting the DVI-D part to work (may depend on which connector you
use).

A motherboard can still complain about missing keyboard/mouse, or
about no boot drive, but then you might see this mentioned on your
monitor.

At one time, Asus had a Vocal POST feature, where there were voice
messages for some of these error conditions. Without that feature,
beep codes and errors presented on the monitor, are the feedback
you can expect.

Are using the same power supply? Reason I asked is that you are saying
you had troubles before you bought the new board-"received second
defective board". Possible but not likely, especially broken with
exactly the same symptoms. Since you do get beep on post you will
probably have all voltages present but a lot of noise on one of the
rails which you are not going to find with a digital volt meter.

Good Luck

Check memory voltage.

It still does although it's not always easy to understand.

 

I have been through two M2N SLI boards. I'm going to try the third
tomorrow. At first, the green light went on, but no beep, even with
everything disconnected.

When I called Asus, every once in a while I would get a techie that
would review the PSU specs and say that this was the problem. He got
off my case when I pointed out that I wasn't running two video cards
yet. I have since upgraded my PSU by quite a bit.

The rest of the story is that I am on my third PSU. It has been two
months and the system is still not up. The first PSU died after a
couple of weeks. The second was out of range. The PSU people think
it's OK to run at 5% off. I remember in the 70s that the old Control
Data disk drives wouldn't work right unless the voltage was within
something like .5% off.

Having done this several times now, I think these new products coming
out now are more of a rush to get products out the door than anything
else, like quality.

 

This may be what you need to hear:

I just got a replacement M2N SLI after two that didn't work. I got a
very good tech. He checked it out and found that there have been BIOS
revisions for the AMD 64 X2 processors, except that somehow the one for
the 5200+ has been delayed or revised and the most recent version is
only four days old.

In my most recent implementation, the POST wouldn't even beep, the
system LED wouldn't light up, when you turned it off the green light
went out immediately. The tech thinks those are all good candidates for
a BIOS upgrade.

The bottom line: get up to date with BIOS revisions. They will send
you the chip and in twenty seconds you have the new one in.

Let you know.

 

You can check that possibility via the CPUSupport page on the support site.
This is the results for a M2N-SLI Deluxe.

People ask for advice it's given they don't take it because they know
better. I think you're the same guy who has posted this same question
again. YOU'RE NOT GETTING ALL THESE BAD BOARDS FROM THE MANUFACTURE you
have only one common denominator and you refuse to check it and I'm
not telling you again. You know best you figure it out. While your at
it, flash the BIOS and really screw it up and then you'll have something
new to cry about.

 

I might have had this same problem. Does your mobo light come on but shut off when you hit the power button? If this is the case I had the power put on wrong for the USB connector. Just leaving it unplugged worked. If not it for you it has to be something like that.
