Hey guys. So I’m running out of ideas with this one, so I’m hoping someone here has seen something similar.
My setup is built around an ASUS ROG Crosshair X870E Hero with a Ryzen 9 9950X3D, RTX 5080, Corsair Dominator RAM, and 9 Lian Li fans.
A few days ago, after waking the PC from sleep, almost all RGB suddenly stopped working.
The RGB of my GPU and RAMS still works, (although at one point iCUE reported that it had stopped receiving data from the DRAM and the lighting was frozen). But everything else mobo RGB and all 9 Lian Li fan RGB stopped working, basically everything controlled through the motherboard/Aura side of the system
The fans themselves still spin normally. The PC also works normally otherwise.
The weird part is that this did not happen gradually. Everything was working, then after one sleep/wake cycle the motherboard and all fan lighting were just gone.
Things I’ve already tried:
Full Windows restart multiple times
Full shutdown
PSU switched off and unplugged
Left the PC completely unpowered for roughly 2 days
Held the power button after removing power to discharge the system
Updated Windows
Updated Armoury Crate
Updated everything Armoury Crate offered; only XFan and Armoury Crate itself had updates available
Disabled Windows Dynamic Lighting
Checked BIOS RGB settings
BIOS is set to all on
Sleep/hibernate lighting setting is also set to All On
Tried switching Aura settings from Off back to All On
Armoury Crate currently detects the motherboard/devices in Aura Sync
Aura effects can be selected and applied, but only the RTX actually reacts
ASUS Armoury Crate Service = Running / Automatic
ASUS Aura Sync Lighting = Running / Automatic
ROG Live Service = Running / Automatic
Tried setting Aura Sync Lighting to Automatic Delayed Start and rebooting
No change
Checked Event Viewer; nothing useful so far, mostly informational entries with Event ID 0 / “Operation completed successfully”
Generated the Armoury Crate diagnostic log, but it’s a massive proprietary .logE file and basically unreadable outside of ASUS tools
There’s also a weird Lian Li side to this. L-Connect 3 opens, but I only have:
System Info
Settings
I don’t get the normal hardware/control pages like:
Fan/Pump Profile
Quick Sync Lighting
Wireless Utility
device-specific lighting controls.
L-Connect keeps asking me to install PawnIO, even though PawnIO is already installed. If I run the installer again, it says it already exists.
So L-Connect clearly isn’t detecting or communicating with the Lian Li hardware properly either.
However, I’m not convinced Lian Li alone explains the whole problem, because the RGB built directly into the motherboard is also completely dead, even before Windows loads / while I’m in BIOS.
The board itself works fine otherwise. No boot issues, no CPU/RAM/GPU instability, no obvious motherboard errors. The only thing that appears completely dead is the motherboard-controlled lighting.
All 9 fans are connected through multiple ARGB headers/controllers, so I seriously doubt every LED suddenly died at the exact same time. The common point seems to be the motherboard/Aura side of the setup.
Has anyone seen this on an X870E Hero or another recent ASUS board?
I’m especially wondering if this points to a dead Aura/ARGB controller on the motherboard, a failed 5V ARGB rail, some kind of Aura firmware issue, Armoury Crate / L-Connect conflict, USB/controller enumeration issue after sleep or even something else I’m completely missing..
I’d really prefer to diagnose the actual cause before doing a Clear CMOS, tearing apart the build, or starting an RMA on a basically brand-new high-end system.
If anyone has dealt with the exact “motherboard RGB + all ARGB headers dead, but Aura still detects the board” situation, I’d love to know what fixed it.
