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.

Asus dark hero z790 14900k Gskill trident z5 ddr5 6800 48gb

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?

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!

***UPDATE***

So after flashing to BIOS 805 I stopped getting code 00 and started getting code 0d with red light signifying CPU issue. Given how rare CPU failures are by comparison to CPU failures I RMA'd the motherboard and ordered a new one.

Upon getting the new one I flashed to 805 and then installed all components except the GPU. I ultimately got error 0d with red light on CPU. I flashed back to the original BIOS and got the same error code. I'm finding it really hard to believe that the CPU is the problem but I'd like to get other people's thoughts on this.

====ORIGINAL POST====

So I just bought an ASUS ROG STRIX x670e-e gaming mobo and an 7950X. I built the system and turned it on. Not surprisingly my boot drive from my previous Intel build wasn't recognized so I used a USB to flash a new install of Windows 10 (I tried Windows 11 first but it said the computer lacked the hardware specs necessary for Windows 11 install). For some reason the wifi module was not working so I finished the install, restarted the computer (still not working), so I hit F2 to go into the BIOS. While searching for the module in BIOS all of the sudden my PC shuts off on it's own.

When I restart the computer I get 00 as the code. Yikes. I can't clear it and I'm looking for help after trying several things to fix this.

Things I've tried to fix this:

1. Unplug all power cables and reseat them.

2. The PSU has 3 CPU power outputs. I tried powering the two CPU Power inputs using all combinations of the 3 CPU power outputs.

3. Try 1 stick of RAM in A2 instead of a stick in A2 and B2. (tried both sticks as the A2 single module)

4. Take off the cooler and inspect the CPU socket for bent pins (I don't see any and no damage to the CPU itself.

5. Tried BIOS versions 922, 805 and default BIOS.

6. Removing the GPU and booting.

7. Tried a new version of the same motherboard

Things I cannot try:

1. Try another CPU. This is the only AM5 CPU I have.

Components installed on the MOBO:

1. Ryzen 7950X with DeepCool CPU cooler

2. ASUS TUF RTX 4090

3. G.SKILL DDR5 TRIDENT Z5 6000 2x32GB (slotted in A2 & B2)

4. Samsung 970 EVO 512GB in M.2 Slot 1

5. GAMEMAX ATX3.0 PSU 1300W

The only component that isn't brand new is the Samsung 970 EVO. That came from a previous build.

Given that the system booted several times without an issue the only thing I could think is an issue was that while I was in the BIOS it got corrupted. Given that the FLBK didn't solve the problem I'm not sure what it could be. It's hard to imagine the CPU, MOBO or PSU just suddenly going bad after working fine the first hour plus that I was trying to work through the initial boot sequences and then windows install. Interested in what else I should try.
