An Asus ROG Zephyrus G14 owner experienced the disappearance of their RTX GPU due to the Windows maintenance task pnpclean.dll, which removed the Nvidia driver package after the GPU had been in Eco mode for approximately 15 days. Eco mode disconnects the discrete GPU from the PCIe bus, causing Windows to register it as missing hardware. The pnpclean.dll routine removes drivers for devices absent beyond a timeout, which is reportedly 30 days by default but observed at 15 days in this case. Switching back to Normal or Hybrid mode makes the GPU reappear, but it is recognized only via the Microsoft Basic Display Adapter, requiring a full Nvidia driver reinstall. To check if a system was affected, users can run a specific PowerShell command. A registry fix involves setting the DWORD Autorun from 1 to 0 to prevent automatic cleanup. This issue is considered rare, requiring extended use of Eco mode, and while no hardware is harmed, the silent removal of the GPU driver raises concerns about automated OS processes. Neither Microsoft nor Asus has publicly addressed the issue as of late August 2026.
