I cant get past debug code 00. I installed i7-13700K, 32GB mem, NVIDIA GPU, power supply, cooler, etc.. when I turned system on lights go on, fans spin, cooler seems to work, but motherboard never progresses past 00. no POST notice either

I took everything out, except CPU & power supply and same result.

I read in forun that it could be CPU, so I bought a i3-12100F to try out. installed it, didnt add memory or anything just to see if it would go past 00 to a diff debug code - same result 00

any ideas?

Hi Xaltar

Looks like you are correct in your assumption.
I pulled all RAMs out of the motherboad as according to some sources the codes i listed could be connected to pre memory test phases, and it passed 28 code.
Then i started to put RAMs one by one after all 4 RAMs totaling 128GB were in place. And voila, got BIOS prompt urging me to set the date (i did CMOS reset prior to that).
I hope the problem is solved. Need to put second GPU and see what will happen.
Thank you everyone who put efforts to help me in solving this issue.

Also, if you have not tried already, power on the system and leave it on for 10mins
at least. It could just be RAM training taking a long time, it can happen sometimes
but should revert to quick POST times once complete. ]]> Thu, 06 Feb 2025 05:37:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=95699&PID=179925&title=z790-taichi-lite-post-problem#179925 https://forum.asrock.com/forum_posts.asp?TID=95699&PID=179924&title=z790-taichi-lite-post-problem#179924 Author: Xaltar

The codes are sequential, even if they are not all listed. Seeing as 28 falls
between CPU and RAM in the chart I linked that would be a CPU or RAM related
code, likely the memory controller but it could also be that your RAM is bad or
isn't inserted firmly enough or there is debris in slots.

You can try removing the RAM and powering on to see if the codes change. If so then
reseat them, if not then it's likely the CPU's memory controller could be dead
and as such is unable to initialize the RAM (acts like none is installed).

Good luck.]]> Thu, 06 Feb 2025 05:35:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=95699&PID=179924&title=z790-taichi-lite-post-problem#179924 https://forum.asrock.com/forum_posts.asp?TID=95699&PID=179919&title=z790-taichi-lite-post-problem#179919 Author: Ash

Unfortunately CPU reseat didn't help.
After power up the code sequence is as - 00 7F 19 00 C0 15 00 12 28
Appreciate if someone can help with codes which are not described in the Taichi Lite Z790 user manual.

I am afraid that CPU can be faulty due to known issue with GEN 13/14 Intel Core i7i9 proc.
Therefore the proper detection of problem needs to be done before Intel will be contacted for CPU replace (extended warranty).
CMOS reset is ongoing and followed by PSU tests.

Thanks for response.
I have only checked 12V coming to CPU and it was fine.
For the rest need to dismount PSU to have an access to the connectors.

Regarding POST codes in the manual - unfortunately most of them are not specified in the User manual for the motherboard.

PC was working fine after latest BIOS update.
I will try to reseat CPU and erase CMOS. Lets see what will happen.

Thank you]]> Thu, 06 Feb 2025 01:20:48 +0000 https://forum.asrock.com/forum_posts.asp?TID=95699&PID=179915&title=z790-taichi-lite-post-problem#179915 https://forum.asrock.com/forum_posts.asp?TID=95699&PID=179914&title=z790-taichi-lite-post-problem#179914 Author: Xaltar

The codes are supposed to cycle, each code represents a step in the POST process.
The only code that matters is the final code before the loop repeats or the code
that gets stuck on the display (depending on the situation). This last code tells
you what part of the POST process failed. Looking up that code should help identify
and resolve your problem.

All the codes should be listed either on ASRock's website or your product manual.
Some are listed as ranges: 00 - 19 for example or 31 - 3b where in 3(x) x can
be any integer from 1 to b (1-9 then a then b)

Try clearing CMOS, you could just have some bad BIOS settings saved. If a regular
clear isn't doing the trick try this:
https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal

If your last code is 00 that means no CPU detected, I doubt it however as code
00 is the very first code in the POST process, no other codes would show if this
one is failing. You should also check your power connections to the motherboard
and reseat the CPU if you still can't get the system to POST. While the CPU is out
double check for bent pins and dirt/debris in the socket or on the CPU contacts.

Good luck.

Exact correct repeating sequence of codes are shown below:

Hi

I recently ran into the problem with Z790 Taichi Lite motherboard - it doesn't pass power on self test.
LED display on motherboard flashes through the sequence of codes in the loop.
Codes appeared on the motherboard LEDs are 00 C0 12 28 7F 19.
PC the motherboard is used in wasn't run a couple of months. Intel gen 13700K was there and few months ago i applied August BIOS update to solve the problem with Intel processors of gen 13 and 14.
No exposure to high temperature or excessive humidity whatsoever.
No overclocking, no gaming. It wasn't in use more than 48 hours totally.

Most of the LED codes shown above are not described in the Taichi Lite Z790 user manual.

Appreciate for any ideas that could help to resolve the issue. ]]> Thu, 06 Feb 2025 00:15:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=95699&PID=179902&title=z790-taichi-lite-post-problem#179902
