I would start the RMA process NOW for the motherboard. It doesn't matter if you actually follow through on the RMA, nor does it matter if you actually SEND the motherboard prior to the warranty date. So long as you've BEGUN the RMA before the warranty expires, you should be good if the CPU doesn't cure the problem. That way, you are already ready to send them the motherboard if the CPU is not the issue and they can't say it's out of warranty because you started the process while it still was.

Question - Asus Motherboard shows Code-00 (No POST a lot of times)(MB: Maximus vii Hero Z97) | Tom's Hardware Forum
January 22, 2020 - During the time when "No POST" happens, I've tried removing RAM sticks and I received the same code. I've also taken my computer twice to the repair shop. These people did the same thing I did. They checked with different RAM (Same Code-00), then they changed the PSU (Same Code-00).

r/techsupport on Reddit: Computer won't start, Q Code error 00 Maximus Hero VII
July 19, 2018 -

My Specs: Asus Maximus Hero VII I5-4690k GTX 970 MSI G.skill Trident X 8gb XFX XTR 550w PSU

So, my computer won't boot after several tries. It suddenly crashed, and it after pressing the power button, the fans and the lights would turn on but no connection to monitor, but now not even the fans work.

In the Q-Code it said 00. I searched online but unfortunately couldn't get to any conclusion. Right now it won't boot, and won't even show any error.

I changed ram, checked cables, pressed the reset button in the motherboard, pressed the star one and after I pressed the "CLR_CMOS" button, the LEDs won't stop blinking, the fans don't work, and it won't start.

I wanted to get some advice on what to do, as I wouldn't want to waste my money on a new motherboard, new CPU and new RAM (because ddr4) and still not have my computer working.

What can I possibly do?

Keep in mind I'm not tech savvy and all I know is from searching about this problem

r/buildapc - Error Code 00 Asus Maximus VIII Hero
December 12, 2020 -

A couple months, I decided to buy parts to build a PC. I'm nearly regretting this decision. I connected all the parts and checked multiple times to make sure that I built it correctly. But, I keep receiving a 00 error code, and I cannot get anything to display on the monitor. I tried taking out the cooler fan, the CPU, and the RAM, and then putting them all back into place. I even tried taking out the battery and clearing the CMOS (though I'm not sure if it actually cleared, because the error code still appeared). Before, I was able to at least get the lights on the motherboard to light up and the fan to spin. But now after taking out the battery and putting it back it, it's not even turning on.

Can someone help me to troubleshoot this? I need to get this resolved before the end of the month since I will be moving then. Any advice is appreciated...

January 22, 2020 -

Hello, For nearly a year I've been receiving error code "00" on my Asus motherboard. No POST happens a lot of times but after turning it off and on for a couple of times(Sometimes just leaving it off for a few hours and then turning it on again) it will again continue to work normally. During the time when "No POST" happens, I've tried removing RAM sticks and I received the same code.

I've also taken my computer twice to the repair shop. These people did the same thing I did. They checked with different RAM (Same Code-00), then they changed the PSU (Same Code-00). And then they say its a motherboard problem and they need to mess with ICs else my computer won't turn on. Another person said my motherboard is dead and I should buy a new mobo instead.

I usually just take the PC back because I know that if I leave it off for a few hours, it ends up working fine(Most of the time it turns on with just a few attempts).

May I know what should I do to fix the 00 error so my computer works fine always?

Things I have tried:

Resetting the BIOS. Works for a day and then it goes back to Code-00 and after 4-5 attempts of powering On and Off it works fine.

Leaving the system on for 10 or so minutes and then retrying (It works most of the time this way). Saw this on a youtube comment once since a lot of people seem to be getting this 00 error. The explanation which the user gave was that the processor needs a bit of warmth. (But again sometimes it doesn't work).

Clearing CMOS and Removing the Battery (This worked the first time I faced the 00 Error. It worked for a few months and when Error-00 appeared again, I tried this method but it didn't work)

Keep in mind, when my computer works it works perfectly. I even tried doing the stress test on CPU-Z and it worked fine. Could it be some major problem still?

Specs:

MOBO: Asus Maximus vii hero motherboard

CPU: Intel Core i7 Processor (4790K) LGA-1150

PSU: Corsair VS650 ATX Power Supply (650 watt)

July 5, 2016 - Code 00 is a code that isn't used, so that's OK, try removing the GPU and run graphics from the mobo's video port, see if you get to the monitor

r/buildapc on Reddit: [Troubleshooting] Asus Maximus VI Hero Q-Code 00
December 29, 2014 -

The motherboard displays the Q-code "00" and won't boot. If the computer sits for an extended period of time—while I'm at work, for example—then it will boot up and run normally. The problem occurs when I shut the power off and try to perform a cold boot immediately after. The CPU fans spin up but not the case fans. My keyboard and mouse do not appear to be powered either.

The Q-code "00" is listed as "not used" in the manual, by the way.

This has happened ever since I put the computer together.

I have tried a few things to remedy the problem:

  • Tried to boot with just one stick of RAM. I tried it in all four slots.

  • Tried to boot with a different power supply.

  • Tried to boot with the HDMI cable plugged into the motherboard with the GPU removed entirely.

  • Tried to boot with all peripherals removed.

  • Reset CMOS.

  • Tried a different CMOS battery.

  • Updated to latest BIOS (1603) using USB flashback. Also tried reverting to BIOS version 1505.

System specifications:

CPU: Intel Core i7-4790K 4.0GHz (stock)

CPU Cooler: Phanteks PH-TC14PE_BK

Motherboard: Asus Maximus VI Hero ATX LGA1150 (obviously)

Memory: Kingston Fury Red Series 8GB (2 x 4GB) DDR3-1866

SSD: Samsung 850 Pro Series 256GB 2.5"

HDD: Western Digital Caviar Blue 1TB 3.5" 7200RPM

GPU: MSI GeForce GTX 970 4GB Golden Edition

Case: Corsair 750D ATX Full Tower

PSU: Corsair 750W ATX12V / EPS12V

OS: Microsoft Windows 8.1 Pro (OEM) (64-bit)

March 6, 2024 - Code 00 can be caused by a few different things a faulty psu, a faulty motherboard or a dead cpu. You could also have bent cpu socket pins and this is what I would like you to check next.

Asus Maximus Hero VIII: Error Code 00 | tonymacx86.com
July 7, 2017 - Trying to switch it on again made it suddenly go out after only lighting the power LED for a second. Luckily I had an identical PSU laying around. Switching it to a different PC where the other one was built in showed it worked perfectly. After building it back it worked again but only brought the system to Error Code 00 on the Mainboard.

November 11, 2020 - After using USB bios flashback for the second time and powering on the machine I got Q-CODE 00 again, but the computer subsequently reset itself (it didn't do this the previous times) and then I managed to boot into Windows and run the Intel Processor diagnostic tool, this completed all stages of the test including the stress test with no issues and passed.

Asus Maximus VII Hero 00 Q-Code | Tom's Hardware Forum
April 23, 2015 - After I restarted, the FE code was gone and in it's place, 00. This is what it should display, so I thought all problems had been fixed. However, nothing came up on my monitor, and I noticed that my cpu and gpu fans were not spinning, as well as the gpu LED not working (The case fans were working though ). I have not been able to find any viable solutions, so I need help. Here are my specs : Maximus VII Hero mono 16gb (2x8gb) corsair vengeance Intel i7 4790k NVidia GTX 970 (Windforce 4GB) EVGA SUPERNOVE NEX650G Thanks in advance.

March 6, 2024 - Unfortunately Qcode 00 is undocumented, however imo, I think it is a hardware failure, Either CPU or DIMMs. Even ASUS support will not comment on this reserved Code, however if you search via Google, There are many opinions on different Forums.
