Hello.
A few days ago, while i was just watching Youtube video (no mouse or keyboard usage at that moment), my system suddenly froze during idle. After hitting the reset button on the case, the system restarted but no display appeared, it was only the black screen. The motherboard Q-LED showed 00 code and the yellow DRAM LED was always on.
Things i tried:
- Unplugged and re-plugged power supply cable
- RAM sticks tested one by one in different slots
- Removed and re-applied thermal paste on the CPU cooler
- Removed and reseated the CPU
- Removed the GPU and tested with onboard video
- Cleared CMOS
- Removed all SSD/HDD
Additional info:
- No overclocking or underclocking was done, only EXPO profile enabled
- Case fans were adjusted due to temperature concerns
- CPU temps under normal use hover around 50-55°C, idle around 40-45°C, but can spike up to 90-95°C during heavy loads despite the liquid cooler running at full speed
- Thermal paste was applied correctly but didn’t help much with temps
- The motherboard is currently at a local authorized service for inspection, but i haven’t gotten any update yet
My build:
- Motherboard: ASUS ROG STRIX B850-E Gaming WiFi
- CPU: AMD Ryzen 7 9800X3D (Batch No: CF2507PGE, Part No: 100-100001084WOF)
- RAM: Lexar Ares 32GB DDR5 6000MHz CL28
- GPU: ASUS Dual RTX 3050 OC 8GB
- Cooler: ASUS TUF Gaming LC II 360 ARGB (running at full speed)
- PSU: FSP Hydro 600W Bronze
I’ve read that some users have faced issues related to CPU batch codes. I’m wondering if my problem might be related to that, and would love to hear if anyone has experience or advice regarding batch-related CPU faults.
I’m not sure if there’s a problem with the CPU, so I haven’t initiated an RMA for it yet. However, in my communication with the service team, they asked me to send it in, as they will likely inspect it. I’m still unsure whether i should send the CPU right now, especially since the motherboard is currently at the service center.

Appreciate any advice or assistance, thanks!

Update:
Hey again, here's an update regarding my motherboard issue:
I sent my motherboard (ROG STRIX B850-E Gaming WiFi) to ASUS via official RMA on August 27. It was returned to me on August 29 with a note stating:
“Display was received from motherboard. BIOS updated to version 1078.”
Unfortunately, the issue still persists exactly the same - no display/black screen, Q-CODE stuck on code “00”, yellow DRAM LED always on.
Here is the photo showing that the motherboard returned from the service is still exhibiting the same error and not functioning properly: https://imgur.com/9IGgFY6
I suspect this is a deeper hardware-level fault (possibly related to the PCB traces or DIMM slots), but the service only did a BIOS update and sent it back.
I’m planning to contact ASUS executive support but, Is executivecare@asus.com the correct email address to contact for this hardware RMA issue? I want to make sure I reach the right department before sending my motherboard back again or possibly my CPU for warranty service.
Also the RMA status on their system hasn’t even been updated it still shows “awaiting device delivery” even though I already received the board back.
I’ll probably have to send it again and ask for a full inspection or possibly request a replacement.
If anyone has been through something similar, or knows if ASUS ever acknowledges issues related to DRAM/CPU signal faults like this, I’d love to hear.
Additionally, I originally sent the motherboard packaged in its shipping box, but when I received it back, the shipping box was missing. The motherboard arrived only wrapped in a thin protective film (like a plastic wrap or razor-sharp protective sheet). Moreover, I noticed some dirt and oil-like stains on certain parts of the motherboard, which concerns me regarding the handling and care during the service process.
Any advice or similar experiences would be really appreciated! Thanks!
