This Stop message indicates that the requested page of kernel data from the paging file could not be read into memory. This Stop message is usually caused by a bad block (sector) in a paging file, a virus, a disk controller error, or failing RAM. In rare cases, it is caused when nonpaged pool resources run out. It is also caused by defective hardware.
If the I/O status is C0000185 and the paging file is on a SCSI disk, the disk cabling and SCSI termination should be checked for problems. Check your computer for viruses, using any up-to-date, commercial virus scanning software that examines the Master Boot Record of the hard disk. An I/O status code of 0xC000009C or 0xC000016A normally indicates the data cannot 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 out the bad sector. If Autochk does not scan the hard disk for errors, 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 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. 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 it. 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.
