Windows stopped with a KERNEL_DATA_INPAGE_ERROR bug check because kernel data requested from the paging file could not be read into memory. This commonly points to failing storage hardware, bad sectors, I/O path problems, defective RAM, or a low-level disk configuration fault.
The system drive has bad blocks or other read errors that prevent kernel data from being paged back into memory.
A storage controller, cable, or device path is intermittently failing, causing low-level I/O errors.
Defective RAM or memory corruption is interfering with page-in operations.
A disk configuration problem or hardware fault caused Windows to lose reliable access to the paging file.
How to fix it
Check the system drive first. Review SMART health and run the manufacturer’s storage diagnostics to identify failing sectors or controller issues.
Run `chkdsk /f /r` on the system volume, ideally from recovery or at next restart, to detect and isolate bad sectors.
Test memory thoroughly with Windows Memory Diagnostic or, preferably, a longer offline memory test such as MemTest86.
Inspect storage hardware connections and controller stability, especially if the system uses older SATA, SCSI, or recently changed storage hardware.
Review Event Viewer for disk, Ntfs, storport, or controller-related errors close to the crash time to narrow the failing component.
If the machine recently began showing multiple storage-related errors, prioritize backup and drive replacement because this stop code often precedes disk failure.
