I've been putting together a computer for the first time today, and I've ran into a big issue. My motherboard is a z390 taichi from asrock, and my cpu is a 9900kf. When powering on, the fans spin, the watercooler starts pumping, and the lights turn on, but doesn't post and spits out the error code 00 on Dr Debug.

According to the motherboard manual, 00 means a cpu problem, and advises to check the cpu and reset the cmos. I've taken the cpu out and put it back in twice, it can't possibly be wrongly installed. The arrow is lined up, and its very snug over the socket. I've just been taking the cmos battery out every time to reset it, so it can't be that.

I'm reusing storage drives from my old, prebuilt computer, that ran on a gigabyte made x370 chipset. I don't really understand drivers and the software side, but is that possibly the problem? It has windows 10, but gigabyte drivers for an amd board, and I'm not sure if that would be a problem.

I've plugged the cpu power cable in and out of the motherboard, no luck. I put the powercable in a different cpu socket on my psu, still no luck. I'm at a loss for what I fucked up here.

Edit: It was the processor. I built a computer about 4 months ago with: mobo: Asrock z690 PG Velocita, Cpu: Intel Core i7 12700KF, Psu: Corsair RM850x, Gpu: OEM Dell RTX 3090, Ram: Crucial 2x16GB DDR5 5600, M.2 Samsung 990 Pro 2TB, A couple HDDs, Optical drive, Thermaltake ux200 cooler

Before the issue instability: every couple weeks I would put the computer into sleep and turn it on a few hours later and it would just be a black screen, no rgb peripherals or monitors lighting up/or responsive. When that happened I would just turn it off with the power button and then turn it back on. Sometimes that worked but if it didn’t I’d turn it back off, then flip the power switch on the power supply, turn on, a few handfuls of codes would cycle quickly thru dr debug, then it would post. And that always seemed to do the trick. I’ve never had a computer this unstable but also never had an asrock board so I just assumed it’s normal for this brand.

The issue: A couple days ago I started computer - rgb fans and board lights working right, cpu and video card fans spinning, fans still at desired slow speeds, but no post and dr debug held a 00 code.

First, I tried clearing the cmos by removing battery for 10 mins and that did nothing except sped fans up to default speed but rgb patterns held settings, debug: 00

Then, I tried removing the cpu, inspected socket, looked under processor, cleared the cmos, reinstalled cpu and cooler, started back up and nothing. Debug stuck at 00 no post. Edit: also forgot to mention that after this, I removed a stick of ram at a time and no luck.

Tested psu: Switched around pci-e and cpu power cables at psu end since rm850x allows that, clear cmos and nothing. 00

Yesterday an Aresgame 750w Guinea pig came in, tried hooking that up instead, Still 00, no post.

Today an i3 12100f and two sticks of ddr5 4800 are coming in to test. While I’m at work though - any ideas on what the issue might be? I’m hoping this isn’t a dead board and just a bad cpu instead because I’d rather try to deal with Intel honestly.

I just finished my new build and tried to get my machine to boot, only to receive the 00 Dr Debug code on my Asrock Mobo. This code is defined as "Please check if the CPU is installed correctly and then clear CMOS."

The first thing I did is strip my setup down to the bare minimum. I tried just the MOBO, RAM, SSD, CPU, and CPU cooler and got the same result. I removed the SSD, and same result. Next I pulled out the CPU to make sure it was lined up properly, then reset it and got the same result. I took pictures of the back of the CPU, the CPU socket, and the general setup of my testing. I have both the 8pin and 24pin power cables connected to my motherboard. I have done the testing with monitor and keyboard/mouse connected and with nothing connected to the rear I/O panel.

Any suggestions on what could be wrong or things I should try? Is it likely that I have a bad CPU or MOBO? (I just bought them both new)

I'm trying to build a new PC, bought all new parts. I choose an Asrock X670-E Taichi Carrara as my motherboard, but the PC will not start and it shows code 00 on DR. Debug. Never worked, completely new build with a new Ryzen 7800X3D CPU. What I tried so far:

1 - Bios flash back to versions 1.28, 1.24 and 1.04, all show the same error

2 - Tested the PSU on another PC, it works fine

3 - Tried with memory, and without memory, with cooler and without cooler

4 - CMOS reset

Nothing works still stuck at 00, PC won't boot or show anything. What else can I try? I'm thinking about asking for RMA.

Full list of components is:

PSU: Super flower leadex III 850W

CPU: Ryzen 7 7800X3D

MEMORY: 2X 16GB CORSAIR VEGEANCE DDR5

VGA: RTX 3070

But for now I'm trying with just PSU, MB and CPU. It should at least progress from 00 to another code.

Here is 2 photos of it. Testing with bios 1.28:

Please can someone help? I'm very frusted and sad with all this situation.

This is a new build, X870E Nova WiFi, AMD 9800X3D, Corsair Dominator DDR5 RAM, 2X 32 GB sticks. I do not have XMP enabled, it is set to standard in BIOS and Task Manager shows 4800 MT/s with 61.6 GB available.

As the title says, the Dr. Debug code changes fairly constantly during bootup. It is currently going between 44, 45, 46, 46, 47, 48, 49, 50, 51, 52 and probably others I am missing, in random order. I saw a few 60s last bootup I'm sure. Restarting does not stop this. The system itself seems to be running fine- I'm posting this from the computer. Games run, I'm connected to the internet, the machine is not laggy.

The internet says these codes are primarily related to the RAM possibly being bad. I don't really know where to start with this, the last time I built a computer it just all worked and I got to AA on first bootup.

Edit: I forgot to say I tried reseating the RAM, which did nothing.

Edit 2: After posting this, I tried resetting the CMOS for old time's sake. Now after boot the display just says 00.

Hi all, I built this PC about a year and a half ago, everything was great up until a week ago, I came home and PC wouldnt boot, got Code 00. No UI on boot. It'd reset itself after 10 or 15 seconds, then power back on with the same code.

For those unfamiliar, code 00 reads "Check CPU installation or reset CMOS.

I've both used the reset CMOS button on the back of the motherboard, and I've removed and replaced the battery.

I didn't have a spare motherboard or CPU so I brought it to a guy at a shop who took the CPU and cooler and put it in a brand new MSI board that he'd confirmed working with other hardware, no luck.

So, I ordered a new i7 8700k (same cpu as before) and just replaced it.... nothing.

8 pin 12v ATX connector is plugged in, RAM slotted properly, GPU slotted properly. All fans working. Everything's plugged into the PSU.

I saw a thread where someone said to flip the physical xmp switch, so for shits and giggles I did that. Curiously, it stopped doing the auto reboot after 10-15 secs when I did that. It just started and stayed on with code 00.

If anyone has anything else for me to try, I'd really appreciate it, I have no clue what it could be. If my cpu didnt work on his mobo, and a new cpu doesnt work on mine...what are the chances I came home to both a fried cpu AND mobo? I already spent a lot on this new cpu :(
