Have you tried performing a clear CMOS? Code 00 is basically before the mobo starts testing the CPU in the first place. Does this happen only in Windows? There were some Asus BIOS versions that didn't play well with software like Argus monitor and the mobo would crash to post code 00 due to that. Answer from Elianor_tijo on reddit.com

How to Fix 'Error Q-Code 00' on ASUS Motherboard
April 29, 2024 - Instable Overclocking – If you overclocked the frequencies and voltages of your CPU, GPU or RAM, you can also expect this motherboard error to occur due to general system instability. In this case, you should reset your overclocked values back to their defaults and see if the issue is now fixed. As it turns out, one of the most common reasons that might be causing the 00 Q error code is an inconsistency that’s perpetuated by the CMOS (Complementary Metal-Oxide Semiconductor) battery. In most cases, this particular ASUS Q error is caused by some type of corrupted data that’s preserved in-between startups and needs to be cleared.

Asus Q-code 00 help

So my GPU died in early 2021 and due to the prices I wasn’t able to get a new one. I got a 3080 recently as the prices have cooled down. I also got a new cpu cooler(Noctua D15). My cpu is the i9-9900k and my mobo is ASUS MAXIMUS hero XI (wifi).

After I installed the GPU and cooler the pc booted with q-code 00. Later, it booted successfully for the first time in like over a year. Then it crashed again with the code 00. Now when I try to turn it on it will either boot successfully for like 10 minutes then shut down again, or just not POST at all. Also the fans don’t turn on when the error is there.

I did research and apparently it is either a dead cpu or a dead mobo, but I really don’t want to get a new cpu or mobo and I don’t have any spare parts. I reseated the ram and tried various configurations, so it isn’t the ram. I also reseated the cpu and cooler, to no avail. If anyone has any advice please let me know. Thanks!

December 8, 2022 - Very similar to what I just did; after reconnecting my cables for the nth time (getting the cables laid out just so), I forgot to connect the two CPU cables. “00” through several reboots until I thought to look for anything out of place. A lovely “duh” moment. lol

The most commonly seen Q-Code errors on Asus motherboards, and how to fix them
February 22, 2024 - It's usually found on some of the more premium motherboards, as opposed to the entry-level or budget options. 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.
