A7N8X Deluxe fails BEEP POST BOOT

[Ken F.]

The problem - NO BEEP, No POST, NO BOOT
A7N8X Deluxe, BIOS C1005 with PCB 2.0
Having succesfully sorted out some of the software problems that I
with this new board I got everything working very well.

Then at one point the system locked up.
I made a change or two in the BIOS and tried to reboot. No go.
No hardware or system changes have been made since it last booted
sucecsfully.
The fans spin up, the power LED on the board lights up

I expect I'm headed for RMA (or a new BIOS chip) but since it's a
weekend and that's a couple of days away at best, I thought I would
note the things that I have tried that have not solved the problem and
see if anyone can offer any further suggestions:
1. The obvious - clear CMOS using jumper, then set jumper back to
default
2. Move the FSB jumper to 100 setting instead of 133/166/200
3. Moved memory around, tried only one stick at a time in different
slots
4. Tried a different CPU (and noted than when no CPU is installed the
board's voice tells me that)
5. Replaced CMOS battery (now 3.25 V, even though the old one measured
3.03V)
6. Tried holding the INS key while powering on.

Anyone have any other thoughts? I am reasonably sure I'm not dealing
with a CPU or memory problem since I have had no success with 2 sticks
of memory and two CPU's all of which were known to be fine prior to
this problem occurring.

Your board just suffered from Bios Death...

I have two sitting here that died the same way.

SOmetimes when you save the settings, for some reason the Bios becomes
corrupt. Then it's no boot.

You might have a chance.

remove every card, and see if the floppy seeks. If it does, you might be
able to recover using the boot block feature.

If not, then it's either RMA, or ordering a chip from badflash.

There's another way, if you know someone who has the same board, it's a
hotflash. wimsbios has the info on that.

From what I have read about this board.. God knows the answer.....
The biggest complaint I see about this board is how it corrupts its own bios
when it doesnt like the settings.. but there is something else

Mine does something similar to yours, sometimes it just refuses to
"Complete" post.....
I hold down the power switch >3 seconds and then it will attempt a reboot
and most times it will start then, I know it sounds silly and simplistic but
give it a try, dont unlpug it or turn the psu off because when mine doesnt
complete post then me doing that seems to put me right back in the same
situation..
Good Luck

The A7N8X Deluxe I built for my father is doing what ''rstlne's'' system is
doing. I did no ocing(set at 333MHz), and it has good Corsair 3200 DDR
memory(for future ocing). The system is fairly simplistic with only 2 HDs
and a CDRW. He has no exotic software and good drivers for his printer and
scanner. Occasionally in the last month or 3 wks(forgot when I finished
building it_very short time ago) it does a partial boot; I found if I go
into the CMOS then exit, the computer will continue finishing the post and
go into Win XP. This is really weird. I've done Chkdsk on all hard drives;
all is well. I've checked basic IDE and power connections. I do have an
ATA 133 controller card with a 80 GB Maxtor 133 ATA HD (used for storage and
as a scratch disk for PhotoShop). The post (when it screws up_only 5 times
in abt. 30 days- but only started abt. 2 wks ago) does not get to the part
of the CMOS identifying the controller with the Maxtor HD and freezes or
does not complete. The controller is suspect, but I've heard of other
people here posting about their system not completing posts (most
overclockers). This may be a bummer bios related problem on Asus's end. I
checked bios history, and there is no mention of this kind of problem. I've
seen several posts similar to this, but "rstlne's" post fits my Dad's board.

I just RMA'd a board for that last week. DOA out of the box. Fans spin, no
beeps, no voice, no anything. Same symptoms with CPU and or memory removed.

Got the new board installed yesterday. Runs great! I'm running it at 200 x
10 but it will go much higher.

XP 2500+ that will OC to 200 x 11.5 ( says XP 3200+)
Crucial 2x256mb
Radeon 9200
etc..

In addressing this problem my options appeared to be (1) replacing the
board or (2) obtaining a new BIOS chip, or (3) finding a way to
reflash the old BIOS chip.

I need this system running and realized that merely putting in a new
BIOS chip might not solve the problem if it was, in fact, something
else. If that were the case simply replacing the chip would be a lot
of wasted effort.

So I got my hands on a new board (no thanks to ASUS says they have no
advance replacement procedure for RMA.)

As I began to install it I thought I might just take the BIOS chip
from the new board and popit into the old board just to see if it is
in fact the BIOS that is bad. However I then came to my senses and
realized that even if the BIOS is bad, that is merely a symptom and
there's no telling what the actual problem might be that that caused
the BIOS corruption. So it's conceivable that I could pop the new
BIOS in and have it trashed too, if not immediately, then perhaps
somewhere a day, week or month down the road. So instead I opted for
completely replacing the board getting it running and then seeing if
the old BIOS would work in the new board.

The short story is that the old BIOS does NOT work when installed in
the new board. The legend of the corrupted BIOS'es seems to be true.

So I ordered myself a BIOS Savior.
