Error Message:



This Stop message indicates that the requested page of kernel data from the paging file could not be read into memory. It might have been caused by a bad block (sector) in a paging file, a disk controller error, a defective motherboard, failing RAM, or because the stack signature in the kernel stack was not found. In extremely rare cases, it is caused when nonpaged pool resources run out.

User Action:

If the stack signature in the kernel stack is not found, the likely cause is defective hardware. Check the disk cabling and SCSI termination for problems. In addition, check your computer for viruses using any up-to-date, commercial virus scanning software that examines the Master Boot Record of the hard disk. Another cause of the Stop message might be that the data could not be read from the disk due to a bad block (sector). If you can restart the system after the error, Autochk runs automatically and attempts to map the bad sector to prevent its further use. If Autochk does not scan the hard disk for errors, you can manually launch the disk scanner. Run Chkdsk /f /r on the system partition. Restart the system before the disk scan begins. If you cannot start the system due to the error, use the Recovery Console and run Chkdsk /r . Caution: If your system partition is formatted with the FAT file system, the long file names used by Windows 2000 can be damaged if Scandisk or another MS-DOSbased hard disk tool is used to verify the integrity of your hard disk from an MS-DOS prompt. (An MS-DOS prompt is typically derived from an MS-DOS startup disk or from starting MS-DOS on a multiboot system.) Always use the Windows 2000 version of Chkdsk on Windows 2000 disks. Another common cause of this Stop message is failing RAM. Run hardware diagnostics supplied by the system manufacturer, especially the memory scanner. For details on these procedures, see the owners manual for your computer. Check that all the network adapters in the computer are properly seated. Use an ink eraser or an electrical contact treatment, available at electronics supply stores, to ensure network adapter contacts are clean. In addition, check the System Log in Event Viewer for additional error messages that might help pinpoint the device causing the error. Disabling memory caching of the BIOS might also resolve this error. Finally, if all the above steps fail to resolve the error, take the system motherboard to a repair facility for diagnostic testing. A crack, a scratched trace, or a defective component on the motherboard can also cause this error.
