A7N8X deluxe no video

[Steve Maring]

I just installed an A7N8X deluxe rev. 2.00

on power up, I get no video and no beeps from the POST.

The card is an AGP Rage 128 Pro. I've tried other AGP and PCI video
cards with no luck. The Rage card works fine in another system.

I've taken all the memory out as well as all none essentials.

Could it be that the CPU went bad during the MOBO swap, or is this a
sign of a bad MOBO?

I do get CPU fan power up and the proper power LED indicators.

Thanks.

Only boards that use 1.5v will work.
Also you cannot have x8 AGP support enabled if the card is not x8 agp(the
Rage 128 is not)
And you cannot have agp fast write enabled if the card does not use it
Video ram cacheable off
also check if the red agp led is not on(2.3 in manual)

 

[JohnJeninga]

Is the AGP card the correct voltage? Did you change the BIOS to select PCI
video fist when you tried the PCI card?

"Is the AGP card the correct voltage? "
That is exactly what I meant by saying only 1.5v cards will work(AGP)and if
not 1.5v then the red led comes on

 

[Steve Maring]

the red led does not come on

since I have no video, I certainly cannot adjust the BIOS settings

I'm also suspicious that I may not be making it into POST. I've tried
resetting CMOS but it does not help.

Does the A7N8X Deluxe rev2.0 suffer from the same NVidia 2 POST death
problem that the rev1.X suffered from?

Not that I know of.
Taken all the Ram out?
Well it will not POST/boot without ram and without ram nothing will work
even in post.
How much ram?
Put one stick in slot one
Power supply, what is it and how many watts?
Cpu, what is is?
What Ram?
PC2100, pc2700, pc3200?
Take soundcard out if you have one
disconnect all drives apart from floppy(if you have one)and hard drive.
Fan on heatsink connected?
Is the monitor power cord plugged in?
is the monitor cable connected?

I've seen alot of posts about no POST issues with this board. Sounds
like there are a couple of culprits. Either you change BIOS settings,
and exit without saving, or you install Corsair DDR 3200 XMS memory.
Looks like my BIOS corruption was caused by the later.

I don't have any other boards that I could use to flash the BIOS. But
even if I did, I don't like the suggestion that the NForce 2 may
randomly corrupt the BIOS again at some point in the future. I bought
this MOBO in an effort to solve probs with prior inconsistent MOBOs.

I am soooo ****ing fed up. I've already spent 5 times the value of
this board in non-billable hours, away from my family, dicking around
with it. I thought I had done my due dillegence when picking this
board, but apparently not.

Can anybody recommend a replacement?

Thanks.

When i recently installed an A7N8X deluxe mobo it turned on with black
screen and the stopped.

Solution: the cpu-fan needs to give info to mobo via the pins on the mobo at
first startup.

try and tell if you use a fancooler that get external power.

the red led does not come on

I had this problem when trying to use a Nvidia TNT2 pro card, I believe it
is
a 3 volt card, but the red led light would not turn on, and no video. My
post
was off beforehand. Using a 1.5v AGP card, all went well.

I've had the A7N8X v2.00 Non-Deluxe for over 7 months, Nvidia card, ATI
card, Corsair ram and it has all worked flawless from day 1, it has none
of the quirks I've seen posted here over the past 7 months about the
deluxe boards, but then again it could just be not many people buy the
non-deluxe version or don't have problems with them and don't post here?

I would RMA the mobo if you haven't already and try another one, or try
the ABIT NF7-S ($99 @ newegg.com in the USA), though I can't say if the
ABIT would work any better for you, just what I would probably buy next.

Well going back to what I said before, the board will only work with 1.5v
cards and not any other.
As far as I remember the Rage Pro is not a 1.5v card and so will not work.
That said, if the other cards that have been tried (AGP)are all non 1.5v
ones then that is why they will work on a board that can use them but not on
that one.
Problem is though that if a PCI one is tried that sould work as long as boot
from PCI and no agp is set.

 

[Fiddler]

Are the other AGP cards all older ones?
What cards are they?

The CPU fan, for the AMD 1800, is powered from the MOBO.

I've tried various combinations of the following to get this thing to
POST:

* single Corsair 512MB PC 3200 XMS stick in slot 1
* single 512MB PC 2700 (unknown brand) stick in slot 1
* jumper setting for FSB freq
* an Antec 350W PS
* an Antec 450W PS
* resetting the CMOS
* Rage 128 Pro AGP graphics card
* S3 Trio PCI graphics card

the only thing plugged in right now is the floppy drive and an AGP
Rage 128 Pro

I'm thinking about calling it quits on this one, unless someone has
some more words of wisdom to impart.

"Rage 128 Pro AGP graphics card"

"* S3 Trio PCI graphics card"
Both cards are not 1.5v,they are older 3.3v and will not work, also the Rage
is an old card and is also not 1.5v.
Get a new card if you can but make sure it's one that runs on 1.5v.(Even if
it's only an MX440)

According to this page, the Rage Pro 128 will work fine. It can run
at 4X and 1.5volts I/O.

Are you able to get sound from the Voice POST ? Maybe the messages from
the Voice POST will give you a hint as to what is wrong. The Voice POST
is an independent subsystem on the motherboard, and AFAIK only needs a
working +5VSB for its functions. Even if the CPU and RAM are removed
from the board, the Voice POST will still do something.

You might also assemble motherboard, CPU, memory, video card and PS on
some cardboard, and see if you can get some life that way. Check that
the CPU heatsink is oriented correctly, that the CPU has some thermal
interface material on it, and that the CPU fan is connected to the
fan header. Some motherboards won't start if they don't think the CPU
is installed properly.

Also, with the board assembled on cardboard, you might be able to
flip the board on edge, and probe the underside of the ATX connector
while someone else holds the board stable for you. You can check the
voltages after the two power_on pins on the panel header are
momentarily shorted together, to see if any voltages are missing due
to a short somewhere.

You might also search around and see if someone has a PCI POST card.
This is a test card that plugs into a PCI slot - the BIOS will
write to the two seven segment displays on the card as the BIOS code
runs. This will indicate whether the CPU is actually running any code
or not.

(If this is a refurb, then you never know whether the previous user
had BIOS trouble. If the board is brand new, I wouldn't suspect BIOS
corruption as the root of the problem. You have to get into the BIOS
to mess it up )

HTH,

Steve,
I'm having EXACTLY the same damn problem with my brand-new A7N8X-E and
brand-new XP 2200+ CPU. Hope somebody else responds to this -- I bought
this board to alleviate problems I had from the get-go with an original
A7A266 (probably the worst piece of crap ever produced). I'm about ready to
go buy a Dell, put a big padlock on the case, and throw out the key.

I had a problem with a A7N8X-Deluxe that was cured by placing
electrician's tape betwen the case and underside of the motherboard. I
also places the insulating washers on the topside.

I also had a problem with the video card not seating correctly. It
seemed OK but when I put in the screw to secure the board it would
pivot slightly and cause problems.

You can find a ground problem by taking the board out of the case and
running it outside. Place it on a piece of cardboard to operate.
Remove your power supply and run just the video card and memory. Use
speakers for the audio post report.]

Hope this helps. Let us know.

 

[Chris]

I also have the A7N8X-E board - AMD 2500+ Barton, Kingmax 512MB Ram.
Tried using 3 different PCI video cards, and one AGP card. Cannot get
any video what so ever. The ram works in a different PC. Bitchin
betty will complain if there is no CPU, but she says nothing when
there is only a CPU in. I'm RMA'ing the CPU and MB to Newegg..(unless
someone has a suggestion?)

I've got the same problem . Doing a exchange for a new one. Real drag.
Order new memory and upgrade to higher speed processor. Order a
different model 512mb pc 2700 corsair memory . I have never had this
much problem with motherboard. I can't see mix and match memory would
work. Memory needs to be the same pc . Not a 2700 and pc 3200. Not sure
about brand being different. All the reviews on newegg have been positive.

But is it the CORRECT Ram for that board!!!
I just put together a system (sorry it is not a Asus, but it was basically a
free motherboard <g>) and I installed a Kingston 333MHz PC2700 256 MB Ram
(Backwards compatible to 266MHz and PC2100) and the system does not boot
with it. I had to purchase a Kingston 266MHz PC2100 256 MB for the computer
to boot. Conclusion: YOU HAVE TO HAVE THE CORRECT RAM!!!

BTW Is the board out of the case....like on a anti-static mat for testing
purposes?

later,
dave
