I. About the blue screen error code 0x0000009f

The error code 0x0000009f, commonly known as the blue screen, is a sign of a Windows driver power state failure. This means that the driver is in an unstable or incorrect power state, often caused by installing a new Windows 10 driver, a system update, or a disk read/write error. Outdated or improperly configured drivers can also trigger this error on Windows computers.
