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!

Hello, For nearly a year I've been receiving error code "00" on my Asus motherboard. No POST happens a lot of times but after turning it off and on for a couple of times(Sometimes just leaving it off for a few hours and then turning it on again) it will again continue to work normally. During the time when "No POST" happens, I've tried removing RAM sticks and I received the same code.

I've also taken my computer twice to the repair shop. These people did the same thing I did. They checked with different RAM (Same Code-00), then they changed the PSU (Same Code-00). And then they say its a motherboard problem and they need to mess with ICs else my computer won't turn on. Another person said my motherboard is dead and I should buy a new mobo instead.

I usually just take the PC back because I know that if I leave it off for a few hours, it ends up working fine(Most of the time it turns on with just a few attempts).

May I know what should I do to fix the 00 error so my computer works fine always?

Things I have tried:

Resetting the BIOS. Works for a day and then it goes back to Code-00 and after 4-5 attempts of powering On and Off it works fine.

Leaving the system on for 10 or so minutes and then retrying (It works most of the time this way). Saw this on a youtube comment once since a lot of people seem to be getting this 00 error. The explanation which the user gave was that the processor needs a bit of warmth. (But again sometimes it doesn't work).

Clearing CMOS and Removing the Battery (This worked the first time I faced the 00 Error. It worked for a few months and when Error-00 appeared again, I tried this method but it didn't work)

Keep in mind, when my computer works it works perfectly. I even tried doing the stress test on CPU-Z and it worked fine. Could it be some major problem still?

I just finished connecting all the parts, click on the power button and nothing, code 00 stuck, i removed all ram sticks but 1, checked psu connectors, clicked on bios clear button. Nothing.

Hello, so I purchased a $200 problematic computer on Craigslist in hopes of fixing it and I think the issue may be with the motherboard. Has anyone by any chance experienced the error code 00? My hardware specifications are as follows:

CPU: Intel Core i7 4770K

Motherboard: Asus Maximus VI Extreme

Memory: Patriot 32GB PC-2400

GPU: Sapphire 7970GHz

From my research, this is not an uncommon error and many people have said that it's a CPU issue. However, I installed the CPU in my other desktop and it works fine. The memory works fine as well. There are no bent pins on the motherboard but could it be that the BIOS is corrupt? What's odd is that the seller said that the issues didn't start happening until he installed Windows 10 and he was somehow able to take screenshots of the hardware specs but after I've taken possession of the computer, I can't even get it to boot. The 00 error appears right away.

If anyone has any pointers on what to check, it would be greatly appreciated.
