Asus motherboard error code 00

[plastiscɧ]

Code 00 = headache and gonna cost money to relieve it.

not as much as maybe assumed. look to #11

I tried the 4790K in the maxicrap gene, no go 00 error. tried it in the msi z87i posted and ran fine, so not nesecelery a dead cpu.

so. D0 says cpu INITIALISATION error. it can def. be the prob is below that level.

Board is weird, does the keyboard flash on psu on. all lights on board light up, power, reset etc. When powered up, none of the cpu, ram etc warning leds light up, just 00 on the display, then a 2 or 3 second cycle, that's it.

these codes put you on the right track. but the solution may be quite different:

i had the code C5, C5, C5 in my brand-new z590.
thought my brand new ram is broken. NO! it was a hair between the electronic contacts.
it took me 6 hours of my lifetime to figure it out....

---

CPU errors so either you tightend the cooler down to hard causing a motherboard wire issue or the CPU is bad/missing pins. I would have added bent pins and bad motherboard but you already checked those?

---

So I would again tell you take EVERYTHING APART. YES EVERYTHING.

Take the Mobo put it on top of the Motherboard box it came in OR on a piece of wood (grounding it and is why it is called breadboarding because it used to be the 'bread board' you would cut your bread on people used to build the parts on top of).

Take the CPU, turn it upside down looking down each 'lane' of pins with a HIGH INTENSE light and best with a magnifying lens. Do you see any bent? If yes, then you will have to risk tryng to CAREFULLY bend them back in line with the others. Worst case you BROKE them. Best case your LUCKY and can bend them back into play. NO they WILL NOT TAKE THE CPU BACK, or replace it, your loss your cost - so we are clear.

Insert the CPU, then did you put Thermal Paste on it ? DId you make sure it is a clean job? None spilling over the sides?

Mount the OEM Fan that came with the CPU.

Now mount ONE STICK of RAM.

Plug in K-V-M (Keyboard Video Mouse) to the Mobo (it should have IGP).

Connect case power to the mobo and the Mobo to on/off switch ONLY.

Power on, can you get to POST.

Once you get successful, then you add ONE THING next, then REPEAT, can you POST? Then add next thing, REPEAT REPEAT REPEAT, till all parts are connected (Mobo, CPu, GPU, RAM, HDD). Then carefully start to mount each part, and as each ONE PART is mounted (one hard drive for example) REPEAT THE TEST.

IF at anytime you get a problem now you know where to look for the issue. You isolated down to the most likely culprit and can test till success. NEVER SPEED through the process, it never works.

i love such technically combative and investigative matters.

Not true, "00" can also mean a bad bios or corrupt bios. The 00 boards have built in bios flash back, if it's not a dead board you can restore it easily....

00 code is 100% cpu problem , might point out to dead cpu sadly. You could try on another mobo to check if it works but most likely cpu just died. Good luck.

I tried reflashing on the maxicrap, tried earliest and latest versions with same result POO

the pages i posted are original from an asus motherboard manual. and, i am not sure about this to 100%, as long they all run with AMI bios the codes will not differ in their meaning or the
basic functionality to display same operations.

"00" in your argumentation in not completely wrong! but it does not mean that the BIOS is damaged in this case, it means that the BIOS chip is corrupted.

kinda toast then

I even thought of that. I swapped the bios chip for a spare from a old board(same type) and flashed it with flashback as before, earliest and latest bios, same results. I am no novice, so know how to check if dead for real. I was looking for a service manual, so i could do some multimeter tests, but cannot find one. both winbond 25Q64FVAI0

am i right in understanding you could not find a user manual for your motherboard?

Asus MAXIMUS VII HERO Manual

or for the chip?

Apparently its possible to get service manuals for them, i could be wrong though. I got a user manual. Figured a service manual might have had tests to test certain components of the board for failure. Something must have failed on this board causing the problem, most likely a major IC though.

[Caring1]

Maybe just a small hint;
"00" is not used by the Mobo

"00" is definitely used for a dead system that wont boot, I have seen a few.

Something must have failed on this board causing the problem, most likely a major IC though.

Ai chip usually near the Ram slots can be a cause of this failure.

 

[plastiscɧ]

do not ask me where i found this one, i was very far to somehow indonesia....

 

[eidairaman1]

Interesting, over the 6 years I've had this pc its been running nearly 24/7 as i only turn it off when I'm gone for more than a day and it's been running at a constant clock speed of 4ghz because sound would start to lag when it throttled down as I'm using a beefy external sound card, but on the other hand it didn't show any noticeable signs of slowing down either and it was always running pretty cool never exceeding 65°c except when rendering videos, i always thought the first thing that would fail would be my graphics card as it runs really hot even with the fans cranked up to 100%
Guess i was wrong lol

You need a server psu to run 24/7

on asus, 00 can also mean the rams not fully pushed in.

Nice Necro pull! I dig it.

And it gives me a chance to notify the public what a 00 post code on AMI bios means. Which is no longer used on these newer gen boards.... for whatever reason.

Post code 00 = Call to Interrupt 19 for boot loader
Generally this code would be armed after post not at or during post.
The keys Alt, "CTRL, Delete" activate it.

Here's a quick read up for you all.

______________________________________________________________________________________________
INT 19h (25) Bootstrap Loader Service

Attempts to load the sector at head 0, cylinder 0, sector 1, of a
diskette or fixed disk into memory at 0:7C00h, and transfer control
there. This sector usually has an operating system bootstrap loader.

--------------------------------------------------------------------------

This interrupt attempts to load the sector at head 0, track 0, sector
1, on the first diskette into memory at 0:7C00h. If unable, it then
attempts to load the sector at head 0, track 0, sector 1 of the first
hard disk. If it is unable to load from either the diskette or the
fixed disk, it calls INT 18h, which calls the ROM BASIC.

If INT 19h is successful, control is transferred to the first byte of
the sector, which has been read in at memory location 0:7C00h. That
is, CS is set to 0 and IP is set to 7C00h.

Notes: This interrupt is not a substitute for a Ctrl-Alt-
Del warm boot. This interrupt is the last action
performed by the Power-On Self Test (POST), which is
activated by Ctrl-Alt-Del. If a user program
attempts to execute this interrupt directly, the
machine may lock up.

To correctly reboot within an application program,
jump to FFFF:0h in memory. That is, set CS to FFFF
and IP to 0. This is the same process that occurs
when the machine is first powered on. Following
these steps will perform a "cold" boot. To perform a
"warm" boot using this method, first set the word at
location 0:472h to 1234h. This will simulate the
pressing of the Ctrl-Alt-Del.

A cold boot initializes all hardware, tests all
hardware, tests RAM, then calls INT 19h to load the
bootstrap loader. This process is performed when the
computer is turned on or a hardware reset button is
pressed.

A warm boot initializes and tests all hardware but
does not test RAM. It then calls INT 19h to load the
bootstrap loader. This process is performed when
Ctrl-Alt-Del is typed.

The sector read from the diskette will in turn read
in the rest of the operating system. A fixed disk
will read in a Partition Table, which will then read
in the correct operating system.

I would like to add my experience of the same.
I have an Asus Maximus VII Formula with i5 4690k.
Same issue but after flashing bios with bios flashback feature (allows to flash bios with cpu ram installed) it started giving ram beeps and when I inserted ram, It processed through cycling post codes and shuts down immediately. Powers itself up and the same loop forever. Then I inserted the video card asuming that the igp might be an issue. Vola once it gave the output through gpu but again the same loop over and over.

Does your Hero have the bios flashback feature ?

 

[maybiler1]

I went to the store to get an m.2 drive today...and when I went to turn on my computer...it didn't post...no image ot anything. (Was working perfectly fine earlier) and the powerbutton turns on the system...but doesn't turn it off. I have taken the drive out and still getting the issue. Any ideas?

Totally irrelevant and has nothing to do with the 00 LED code which occurs Pre-Post during the CPU init phase.

Uh... no, it is exact and 100% relevant. You must have misread something somewhere.

It's not used. And it certainly does NOT mean the ram "isn't pushed in" because it's an unused code. period.

If you wanted to know if the memory is not pushed in and do receive 00, you could always try the diagnostic speaker.

I'll list AMI beep codes so you can have better diagnostics in the future.


1 short DRAM refresh failure The programmable interrupt timer or programmable interrupt controller has probably failed
2 short Memory parity error A memory parity error has occurred in the first 64K of RAM. The RAM IC is probably bad
3 short Base 64K memory failure A memory failure has occurred in the first 64K of RAM. The RAM IC is probably bad
4 short System timer failure The system clock/timer IC has failed or there is a memory error in the first bank of memory
5 short Processor error The system CPU has failed
6 short Gate A20 failure The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller
7 short Virtual mode processor exception error The CPU has generated an exception error because of a fault in the CPU or motherboard circuitry
8 short Display memory read/write error The system video adapter is missing or defective
9 short ROM checksum error The contents of the system BIOS ROM does not match the expected checksum value. The BIOS ROM is probably defective and should be replaced
10 short CMOS shutdown register read/write error The shutdown for the CMOS has failed
11 short Cache error The L2 cache is faulty
1 long, 2 short Failure in video system An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered
1 long, 3 short Memory test failure A fault has been detected in memory above 64KB
1 long, 8 short Display test failure The video adapter is either missing or defective
2 short POST Failure One of the hardware testa have failed
1 long POST has passed all tests

NOTE: Some of these codes may be different depending on whom wrote the bios for a particular make and model board, but these haven't changed much in the last 20 years that I'm aware of.

on Asus boards QCode 00 is seen when the CPU pre-post has failed for any number of reasons, including missing microcode, incorrectly installed memory, stuck register on warm-reset, etc, it has no diagnostic meaning in a firmware manual because it is in the realms of anything could be wrong - including dead CPU.

You sound like a university bred engineer, all theory and no relevant experience with the part.

The meat of your post is only relevant to legacy bios AMI roms, it has no relevance to Aptivo 4, 5, etc EFI.

So you're saying code

00

Has a laundry list of definitions?

Anything could be wrong?


-----
Then code 00 means nothing, try the diagnostics speaker for definitive errors.

There will be an error BEEP code for exactly ever single thing you listed that 00 means... which 00 means nothing cause you're telling me it becomes a guessing game and we should rely on...

Post code 00 could mean ANYTHING or simply nothing at all....
