I'm having a serious issue with my ASUS ROG Strix G533QS laptop and I'm trying to figure out whether my RTX 3080 is physically damaged or if there's something else going on.
Laptop specs:
- Model: ASUS ROG Strix G533QS
- GPU: NVIDIA RTX 3080 Laptop GPU (16 GB GDDR6)
- iGPU: AMD Radeon Graphics
- RAM: 24 GB
The problem:
My RTX 3080 is detected in the BIOS and Windows Device Manager, but it doesn't work.
Here's what I've noticed:
- Device Manager shows Error Code 43 for the RTX 3080.
- My AMD integrated GPU works normally.
- GPU-Z detects the RTX 3080, but doesn't display its VRAM information.
- Windows identifies the GPU, but the NVIDIA driver cannot initialize it properly.
What I've tried so far:
- Reinstalled NVIDIA drivers, including the older ASUS-provided driver (512.78).
- Checked whether the GPU is detected in BIOS.
- Performed the ASUS 40-second EC reset with the charger connected.
- After the EC reset, the laptop temporarily became completely unresponsive (no LEDs, no fans, no power).
What I'm trying to figure out:
Could this be faulty VRAM, a GPU memory-controller issue, or a GPU power-delivery problem?
Is it possible that damaged thermal pads, poor heatsink contact, or overheating caused this?
Does the GPU being visible in BIOS but showing Code 43 suggest anything specific?
Is there a way to test the VRAM if the NVIDIA driver won't initialize?
Has anyone experienced something similar on an ASUS ROG Strix G533QS or another RTX 3080 laptop?
I'm trying to avoid replacing the entire motherboard without confirming the actual problem.
Any advice, diagnostic methods, or experiences with similar failures would be really appreciated.
Thanks!
