I am having issues with my build. There is no display and no boot/post. My motherboard LEDs are on and stays on unless I switch off power. The fans are all running- PSU, CPU fan, even the GPU fans are running. My motherboard is giving me Q-code 00 and on my little motherboard display screen it says CPU CODE 00. The Q-LED also displays a Red light which indicates an issue relating to CPU. See below for picture.

I have started an RMA process with Intel but I want to see if anyone can recommend any steps I may have not taken already or perhaps someone has run into this problem and fixed it? Please read thoroughly.

All parts are/were brand new.

CPU: Intel Core i9-10980XE CPU 2: Intel Core i9-10900 (Have not yet tried, picking it up tomorrow from my storage to test for boot/post/display)

MOBO: ASUS Prime X299 Deluxe II

RAM 1: Corsair Dominator Platinum DDR4 64GB 3600mhz RAM 2: Corsair Vengeance RGB Pro DDR4 16GB 3600mhz

GPU 1: RTX 2080 TI Founder’s Edition GPU 2: RTX 2080 TI Gigabyte GPU 3: RTX 2080 TI ASUS GPU 4: RTX 2080 TI ASUS GPU 5: RTX 2080 TI EVGA GPU 6: No GPU

PSU 1: EVGA GQ Series 850w 80 Plus Gold Modular PSU 2: Corsair CX Series 750w 80 Plus Bronze PSU 3: Corsair HX Series 1200w 80 Plus Platinum Certified Fully Modular

CPU Cooler 1: Corsair iCUE H150i ELITE CPU Cooler 2: Cooler Master - Hyper 212 Black Edition 120mm CPU Cooler 3: No Cooler

SSD: WD_BLACK 1TB NVMe SSD

Steps I have taken:

CMOS

• Tried resetting CMOS through CMOS_Reset button on mobo

• Tried resetting CMOS by removing battery cell for 7 hours

• Tried resetting CMOS by removing battery for 10 minutes and attempting to power on 3 times during so

MEMORY/RAM

• Tried reseating RAM

• Tried booting with only one RAM stick in different slots

• Tried completely different RAM

CPU

• Tried reseating CPU

• Tried clearing thermal post off CPU

• Tried blowing dust/dirt/debris off CPU

• Tried looking for bent pins on socket + CPU

• Tried looking for blown fuses

• Tried moving modular PSU to CPU cable connection to different PSU port as well as mobo port; my mobo has two CPU ports but it refuses to spin fans or show any signs of boot or fan spinning if I have both motherboard CPU ports plugged in.

• Tried running CPU with two different CPU coolers as well as no cooler

PSU

• Tried 3 different PSU all of which were brand new and tested on my i7 build except for 1200w but PSU isn’t problem as motherboard showing signs of consistent life/doesn’t turn off by itself.

CASE/CHASSIS

• Tried looking for any short circuits or grounding issues

• Tried removing/decreasing amount of standoffs

EVERYTHING

• Tried to unplug and re-plug everything

• Tried to look for any loose connections

• Tried to push in connections anyways

• Tried with several GPUs and without GPUs

• Tried different power cable

I tried a couple other things but all didn’t work. I’m hoping to avoid RMA but if I have to I will. Trying my spare i9 10900 tomorrow. If it boots then it probably is dead. Thinking about also buying another X299/Lga2066 mobo just to fully test out if 10980XE is actually really dead. Will keep you guys updated.

UPDATE

I tried my spare brand new i9-10900X and it is still giving CPU CODE: 00. The good news is that I am positive that my 10980XE does not need RMA. But now the only thing left here is my motherboard. That is the only thing I have not changed throughout this whole process. If anyone else has this issue, I hope this helps anyone else having CPU CODE: 00.

Hi all, I delidded my 13900KS (didn't run it stock at all) and it's been performing fantastic. Recently achieved 43,600 in CBR23. However, on most cold boots (PC has been off for >10 minutes), my motherboard (Z790 Apex) will cycle through all Q Codes - hit 00 for maybe 10 seconds, and then cycle through Q Codes again and then boot. It will never not finish booting, but it'll always stop at 00 for these 10 seconds.

Once it boots, going through the benchmark suite (3D Mark, Cinebench, OCCT, etc.) there are no issues whatsoever and performance is awesome. I can pull up to 550W on the KS at 27 ambient and maintain 95-98 degrees.

However, I'm concerned about the 00 error. I've remounted the block I'm using and diagonally tightened 5 times and I still see this issue. I've also clean reinstalled windows, RMA'ed the Z790 Apex, tried a different GPU, removed all IO, swapped cases (thought there was maybe a short). Is there any other cause for this that I'm missing? Or is this normal? Thank you!

Hey, i just installed my new Intel I5 11600k and Asus maximus XII formula today and I'm getting cpu code 00 and no outputs at all.

My previous build was: intel i5 9400f Asrock phantom gaming 4 mobo Asus tuff 3070 gpu Asus 850w gold pau Ripjaws v 2666mhz ram 2x8gb A sata 6 boot drive of some sort Firecuda m.2 ssd drive for storage A maelstrom 120T aio

All parts are the same except the mobo and cpu

I don't have another lga 1200 socket or mobo to test on and all other parts worked fine with 0 issues for the past 9 months.

Not sure how this happened 7950X for reference. Temps sometimes went to 90C but never experienced shutdowns or anything. Turned off my PC (It was working fine I was playing intense games) one night and tried to turn it on the next morning and got code 00 on my mobo and it wouldn't post. Want to make sure this doesn't happen in the future but I am not sure what even happened and how to prevent it.
