ASUS TUF F15 FX506HC RTX 3050 Laptop GPU stuck on persistent Code 43 after full clean reinstall + OEM INF install + thermal repaste
​
Laptop:
ASUS TUF Gaming F15 FX506HC
i5-11400H
RTX 3050 Laptop GPU
Windows 11 25H2 Build 26200.8328
Issue:
My RTX 3050 Laptop GPU is permanently stuck on Code 43.
The GPU is:
- detected in BIOS
- detected in Device Manager
- visible on PCI bus
- NVIDIA driver service (nvlddmkm) can start
- but Windows disables it immediately after initialization
Symptoms timeline:
- For a long time the GPU would work at idle but crash under load/gaming
- Earlier I used to get VIDEO_TDR_FAILURE (nvlddmkm.sys)
- GPU temperatures previously reached 90°C+
- Over time the issue worsened
- Now the GPU enables briefly then immediately goes Code 43
What I already tried:
- Full clean Windows reinstall (deleted all partitions)
- DDU in Safe Mode
- Multiple NVIDIA drivers
- ASUS OEM NVIDIA driver
- Manual INF installation through “Have Disk”
- Intel chipset + Intel UHD drivers first
- Disabled Windows auto driver updates
- BIOS reset
- VMD disable/re-enable
- OEM INF binding (nvam.inf)
- NVIDIA Pixel Clock Patcher restore
- Clean thermal repaste using NT-H1
- Re-mounted heatsink with proper cross-pattern torque
- GPU temps now normal (~67°C instead of 90°C)
Current behavior:
- BIOS still detects NVIDIA GPU
- Device Manager sees RTX 3050
- Driver attaches successfully
- During enable, Windows says:
“Windows successfully enabled this device, however this device is still not working properly.”
- Then Code 43 returns immediately
nvidia-smi output:
“NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver.”
Additional weirdness:
- WiFi drivers were randomly disappearing earlier as well
- GPU sometimes appears to work for 1 second after disable/re-enable before failing again
Question:
At this point does this behavior strongly indicate:
- VRAM degradation?
- GPU memory controller failure?
- BGA microfracture?
- Power rail instability?
- Or is there still a realistic software/VBIOS angle left?
Since BIOS still detects the GPU and the driver can bind to the device, I’m trying to determine whether this is conclusively hardware-level or if there’s any remaining advanced diagnostic path worth attempting.
Would appreciate input from anyone experienced with ASUS TUF RTX 3050 failures specifically.
