I understand your frustration. However, a driver update alone is unlikely to physically damage a GPU. Since the NVIDIA card first appeared as a hidden/faded device and is now no longer detected, the priority is to determine whether Windows, BIOS, or the hardware can still see the card.
A few things I would check next:
- Open Device Manager > View > Show hidden devices and also check for any Unknown devices. Then select Action > Scan for hardware changes.
- Check Windows Update > Optional Updates for any available display driver updates.
- In BIOS/UEFI, verify that the PCIe/discrete GPU is enabled and that integrated graphics is not forcing the system to ignore the NVIDIA card.
- If this is a desktop PC, power off, unplug it, and reseat the graphics card and its PCIe power connectors. A loose connection can cause the GPU to disappear completely from Device Manager.
- If the issue started immediately after the Intel driver update, try System Restore or rolling back to a restore point created before the update.
If the NVIDIA GPU does not appear in BIOS, Device Manager, or NVIDIA's installer, even after reseating the card, that may indicate a hardware problem rather than a driver issue.
To help narrow this down, is this a desktop or laptop, and what is the exact NVIDIA GPU model?
Feel free to update here if anything comes up!
