Z790 Godlike won't post, debug code 27/28/29
Had a power surge and now the computer doesn't seem to be posting. What do these debug codes represent? They aren't listed in the manual. On one reboot it sort of cycled between 28 and 29, another time it's stuck on 27. More on forum-en.msi.com

May 22, 2023 - Thanks -- the issue's resolved though, the problem was that the monitor needed to be unplugged/replugged in after the surge in order to get it to display properly again. Before that, the lack of visuals made it tough to realize that I had actually made it through to the OS and that the debug LEDs had switched away from debug codes to temperatures.

Motherboard error codes explained - For Gigabyte, ASUS, and MSI motherboards
February 5, 2024 - The most common Gigabyte Q-Codes seem to be AB, 27, 70, D0, 03, and DB. Thankfully, a website exists dedicated to finding ASUS fault codes. Tap your code into ASUSQCode and get answers in seconds. The most common ASUS Q-Codes are A2, 55, 99, 80, 76, 40, and 62. There’s no website built specifically for MSI fault codes, but there is a dump of ALL fault codes that can be found on MSI motherboards over on the MSI forums.

The most commonly seen Debug Code errors on MSI motherboards, and how to fix them
February 23, 2024 - Just like Asus and other motherboard makers, MSI also has a long list of codes that you may see on your motherboard's Debug Code LED. But most of them are just "status indicators" that tell you what the system is actually doing at any given point during the boot, meaning you don't have to worry about them much.

Hello,
one of my relatives have an issue with his pc with MEG X570 ACE.
The desktop was working fine, suddenly, while doing his job, the screen lost the sync with the pc and never came back.
After rebooting the desktop the debugging display showed all those codes 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, and more, in loop and without posting.
