r/MSI_Gaming on Reddit: MSI MEG x570 Unify: Debug code "00" when powering on the pc
June 13, 2020 -
I bought a new MSI MEG x570 unify mainboard from Amazon.de and it is working properly most of the time but has one major issue:
When I turn on my pc after being away a few hours it displays the debug code "00", most fans of the system start spinning at a fixed rate and the LED of my GPU turns on but there is no video output.
I found two methods that work to help getting the motherboard back to normal:
-
Clearing CMOS will make it possible to boot on the pc afterwards but you will lose all personalized settings you did in the BIOS, ex. PWM Fans and RAM frequency settings.
-
Turning the power supply unit off and back on while the pc is turned on will make it possible to boot the pc normally and no settings are lost.
These two solutions are useful in the meantime but I don't want to do this on the long term so I am still searching the underlying cause of this error. I will be thankful if somebody has a suggestion on how to fix this problem.
I already tried to solve this by flashing the latest non-beta version of the motherboard BIOS (Version 7C35vA3), I also installed the Drivers from the Support website of the mainboard but it did not solve my problem.
August 2020 update: I did multiple bios updates (currently A5) but it still happens sometimes...

MEG unify has no 00 error code. But it shows briefly when you power it once 00 than the initialization codes start passing. I think your board just hangs when it is powered on. I would suspect about power connections especially the cpu power. It could be a faulty PSU or power cable too. Check the sockets also check the power pins when you take them out.

Ok guys I just now solved this "debug showing 00" and fan speed issue by uninstalling and then reinstalling Dragon Center. Upon reinstall of the Mystic lights component it then prompted me with a diagram telling me I had out of date LED software and that I needed to use a pen to short my LED pins which would then initiate a firmware update (seriously, wtf is this, the year 1999?). The firmware then installed and voila... I had all of my LED and fan speed functionality back. However, that is seriously poor and unintuitive software development from MSI. :)

January 30, 2025 - Im also in the process of finishing an almost identical build with the same motherboard (the build above is for my cousin) and I will see if the behaviour is the same on my PC too. ... Update: I finished the second build and it works with no problems either. I tested it in some games for a few hours and no problems showed up. However this one has a permanent code 08 stuck on the display. It sometimes goes to 00 too, but it's at 08 for most of the time.

August 1, 2016 - Code 00 indicates you have a dead CPU. Technically it indicates a late CPU initialization, but in my experience it means the processor is dead (bad delidding attempts).

December 7, 2015 - Replacing the motherboard is only helpful if it's the cpu seat and not the actual processor. What is your opinion? ... I suggest checking firstly the CPU socket (take the board outside the case firstly). If no bent pins, try reinstalling the CPU, the Intel stock CPU cooler, connecting both 24 and 8 pin power cables and starting the board (still outside the case). See if the CPU fan does spin and if still 00.
