Laptop graphics card not detected
4.5
The dedicated GPU (Nvidia/AMD) is missing from Device Manager or games.
Symptoms
- Low FPS
- GPU missing in Task Manager
- Error Code 43
Possible Causes
- Driver corruption
- BIOS setting
- GPU hardware failure
Step-by-Step Fix
1
Check BIOS
Ensure "Discrete Graphics" is enabled, not set to "Integrated Only".
2
Use DDU (Display Driver Uninstaller)
Completely wipe drivers and install fresh from the manufacturer.
3
Check Power Connection
Ensure the laptop is plugged in; some GPUs hide on battery.
When to See a Technician
If DDU doesn't fix it and it's not in BIOS, the GPU chip may have desoldered due to heat.
