I have a Lenovo LOQ 15IAX9E with an Intel i5-12450HX, 16 GB of RAM, Intel UHD Graphics, and a dedicated NVIDIA GPU running Windows 11 Home. After several months without problems, I started getting frequent DRIVER_POWER_STATE_FAILURE blue screens with error 0x9F. They first appeared after closing games, then after restarting following driver updates, and now they can happen unpredictably.
I used Display Driver Uninstaller to remove and reinstall both the NVIDIA and Intel graphics drivers, including the versions listed on Lenovo's support page, but the crashes continue. I currently have the NVIDIA GPU disabled in Device Manager, which seems to help, but that is not a practical long-term solution because I need the laptop for gaming and school.
I have five recent minidump files available for analysis. What should I test next, and does this sound more like a driver problem or possible hardware failure?

Because the laptop is around a year old, check the warranty status before doing anything risky. If the crashes continue with Lenovo’s drivers, current BIOS and chipset software, and the minidumps consistently implicate the dedicated GPU, run Lenovo’s built-in hardware diagnostics and contact support. Repeated 0x9F crashes can be software-related, but a GPU, motherboard, or power-management fault is possible if a clean driver setup does not resolve them.
A 0x9F error usually means a driver failed to complete a power-state transition. On this model, the NVIDIA driver is a strong suspect, although hardware cannot be ruled out. Since laptop manufacturers sometimes customize the graphics drivers, start with a clean installation of the Intel and NVIDIA versions from Lenovo’s support page rather than immediately using the newest generic packages. Test the system after each driver installation, then try newer Intel or NVIDIA releases one at a time if the Lenovo versions are stable.
Use the minidumps to identify the driver that was waiting when Windows crashed. If they repeatedly point to the NVIDIA driver, test with the NVIDIA GPU enabled but install an older, known-stable Lenovo driver rather than assuming the latest release is best. Install only the display driver and required components, and avoid adding extra overlays or tuning utilities while troubleshooting. Also check Lenovo’s BIOS, chipset, power-management, and firmware updates, since power-state failures are not always caused by the graphics package alone.
I already installed the Intel and NVIDIA packages from Lenovo’s support page. I’m also fairly sure the NVIDIA GPU is involved, but I’m not sure how to test it properly since disabling it is the only thing that has helped so far.
