Is My RX 550 Failing? LiveKernelEvent 1b0, AMD Driver Crashes, and Code 31

**RX 550 4GB (Sapphire) - Driver crashes, Code 31, LiveKernelEvent 1b0**

I'm troubleshooting a Sapphire RX 550 4GB on Windows 11.

Symptoms:

* RX 550 is detected correctly in Device Manager and GPU-Z.

* GPU-Z shows normal information (Lexa GPU, 4GB Samsung GDDR5, sensors working, normal temperatures around 46°C idle).

* AMD Adrenalin 23.11.1 installation freezes around 80%, requiring a force shutdown.

* After crashes, Device Manager shows:

* Code 31: "Windows cannot load the drivers required for this device."

* Reliability Monitor logs:

* LiveKernelEvent Code 1b0

* AMD Bug Report Tool appears after crashes.

* Monitor is connected to my Vega 11 iGPU, not the RX 550.

* Windows remains usable on Vega 11, but the RX 550 becomes unstable in the background.

* The card displays BIOS and can boot into Windows.

* When I first got the card, it occasionally flickered to a black screen, but didn't crash.

* Crashes can happen while browsing or even sitting idle, not only during gaming.

What I've checked:

* GPU-Z detects the card correctly.

* BIOS information appears normal.

* Temperature, clocks, voltage, and power readings are available.

* Hardware ID:

PCI\VEN_1002&DEV_699F

Questions:

  1. Does this sound more like a failing RX 550, a VBIOS issue, or a driver problem?

  2. Has anyone seen Code 31 + LiveKernelEvent 1b0 with an RX 550 before?

  3. Any recommended tests before I conclude the card is faulty?
