Yesterday I tried setting PBO through Ryzen Master. Not sure what I exactly did but it started to run a PBO optimizer which runs for about 40 min. Everything was working great temps were low nothing higher than 70c. I went to walk my dog and came back to a black screen and error code 00. It has happened before but I just shut it off a used the Clear CMOS which helped it boot back on. But now It won't post and All I have a is black screen, fans working everything powers on just that dreaded 00 code. I just put in my new 7800x3d CPU Friday.
Not sure what is going on anyone ever had this happen?
Update 2: bios flashback to 3.10 helped to resolve the problem. hope the issue will be addressed in future bios updates.
Update 1: I was running BIOS 3.17 beta (someone who got that bios from Asrock support email posted it here on Reddit) when problems appeared. Then I tried 3.16, 3.18 beta and 3.15, for all 3 versions I was getting code 00. Now tried original BIOS 3.10 that my board came with (there's even a sticker "3.10" on a plate), and I managed to boot into BIOS.
I’m running into a serious issue with my ASRock X870E Nova motherboard and Ryzen 9 9800X3D after performing a CMOS reset. My system was working fine before, but now it won’t boot and is stuck on post code “00” with no display output (even from integrated USB4 and HDMI ports).
My Bluetooth wasn’t working in Windows (no bluetooth in device manager), and I read somewhere that a CMOS reset could fix it after connecting wifi antenna. After shutdown from Windows I pressed the CMOS reset button on the motherboard. After that, my system failed to boot with 00 on the debug postcode display. I tried to fix it by flashing multiple BIOS versions using BIOS Flashback, which appeared successful (flashing light blinked with increasing frequency and stopped as expected). But even after flashing, I still get 00, and my monitor gets no signal. I removed Nvidia GPU, SATA and NVME SSDs and left one RAM stick. Still "00" on the debug display. Placed RAM stick into 2nd slot instead of 4th (4th is the correct one in single stick setup) - got code AA 21. CPU heatsink is cold. NVME drive was warm. Used "bios flashback" button to flashback 3 different bios versions (3.15, 3.16 and latest 3.18 beta) - no effect, still 00 code.
What to do? Currently thinking either CPU or the motherboard died, maybe both. Is there anything else I could figure out before I go through RMA for either CPU or motherboard? I don't think repasting CPU and reattaching cooler could do anything since before first CMOS reset I didn't do anything with my hardware.
My setup:
* 9800x3d
* x870e nova
* Asus ROG STRIX 1000G 1000W
* CORSAIR Vengeance DDR5 64GB (2x32GB) DDR5 6000MHz CL30 CMK64GX5M2B6000Z30
* nvidia rtx 4090
* 990 pro & 980 pro nvme ssd
I was moving a cable in my PC while it was on and one of my cpu cooler fan blades broke off because the cable hit it. My cooler won't spin and I got error code 00 so I got a new cooler and the same thing happened. I put a new CMOS battery in and the cooler spins now but I'm still getting error code 00. Any ideas? Thanks.
what does code 00 correspond to in the manual?
not sure about asrock mobos but try finding like a reset switch or something, a jumper or something
my thought is that the asrock mobo went panic mode when the cooler broke down
if not try finding a diffrent cpu to put into that mobo and see if its your cpu or not (if you dont have one at hand try asking a friend)
