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

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!

July 15, 2018 - Click to expand... In my experience, 00 has always been a dead CPU. What thermal paste did you use? If it is conductive, I'd bet money you shorted some contacts on the CPU and fried it. It doesn't take much, and unless you used a very bright light and a magnifying glass, you probably didn't clean it well enough.
