So I had the same issue on my ROG STRIX X670E-E motherboard….this is what I did. Power off PC Power off power supply Hold down the start button on the motherboard for 30 seconds Press and hold the “clear CMOS” button on the back for 5 seconds. (it’s really small it should say ‘clear cmos’ above it) Power back on It should post and ask you to press F1 to enter BIOS Save and exit BIOS and it should restart automatically. Good luck…hope this helps. Answer from OG_BOBBY_JOHNSON_ on reddit.com

r/ASUS on Reddit: X670E-E Motherboard 1A error potential fix?
February 16, 2024 -
Pc won't boot the first time and will display a 1A error and fans and everything will spin, but a quick shut down and restart fixes it and everything works like normal. Ram is in correct spots and everything appears to be working correctly besides that. Just wondering if its a bios update that's needed or something worse.

Had a simular issue (when rebooting) but on a B650E mainboard and a BIOS flashback to a lower BIOS version lowers the change to have this issue.

Troubleshooting ASUS Motherboard Error Q-Codes — Everything you need to know
August 15, 2022 - Even though debug codes are immensely helpful with troubleshooting issues in your PC, most manufacturers, including ASUS, only ship them with a handful of higher-end motherboards. You can either cover it up by attaching a piece of tape over it or you can turn the Q-Code display off in the BIOS settings.

r/ASUS on Reddit: Can anyone point me towards a list of Q-codes?
April 21, 2024 -
I recently completed a new computer with a StrixX670E-E and, after a short time, it failed to boot and showed a memory error code.
I contacted support, sent it back, and they sent a replacement.
I reassembled my PC and, while it starts, it shows a series of Q-Codes (most appear around memory again) and I am hoping to try and figure out what is going on and, if possible, fix it before it breaks again.
However, I am unable to find a comprehensive list of codes and can only find people talking about them in various forums with generalized and surmised meanings. It would be really nice to have something more official (and which I could use to try and figure out how to diagnose the underlying issue and try and solve it).
Can anyone help me find one?

The most commonly seen Q-Code errors on Asus motherboards, and how to fix them
February 22, 2024 - A Q-code LED, in case you are wondering, essentially displays a two-digit code to denote the status of your PC. It's more of a status indicator than an error code LED, and you may notice it cycling through a bunch of rapidly changing codes before it settles on one as your PC finally boots. Simply buying an Asus motherboard with a Q-code LED isn't enough, as it's equally important to know what they mean and how you can troubleshoot based on the code that's showing up on the motherboard.
