Stop 0x77 or KERNEL_STACK_INPA GE_ERROR

The Stop 0x77 message indicates that a page of kernel data requested from the paging (virtual memory) file could not be found or read into memory. This Stop message can also indicate disk hardware failure, disk data corruption, or possible virus infection.

Interpreting the Message

This Stop message has four parameters. The following set of definitions applies only if the first and third parameters are both zero:

1. This value is 0x00 (zero).
2. Value found in the stack.
3. This value is 0x00 (zero).
4. Address of signature on kernel stack.

Otherwise, the following definitions apply:

1. Status code
2. I/O status code
3. Page file number
4. Offset into page file

Frequently, you can determine the cause of this error from the second parameter, the I/O status code. Some common status codes include the following:

• 0xC000009A, or STATUS_INSUFFICIENT_RESOURCES, indicates a lack of nonpaged pool resources.
• 0xC000009C, or STATUS_DEVICE_DATA_ERROR, generally indicates bad blocks (sectors) on the hard disk.
• 0xC000009D, or STATUS_DEVICE_NOT_CONNECTED, indicates defective or loose data or power cables, a problem with SCSI termination, or improper controller or hard disk configuration.
• 0xC000016A, or STATUS_DISK_OPERATION_FAILED, also indicates bad blocks (sectors) on the hard disk.
• 0xC0000185, or STATUS_IO_DEVICE_ERROR, indicates improper termination, defective storage controller hardware, defective disk cabling, or two devices attempting to use the same system resources.

Resolving the Problem

The following suggestions are specific to Stop 0x77 errors. For additional troubleshooting suggestions that apply to all Stop errors, see the section titled "Stop Message Checklist" later in this tutorial.

• Stop 0x77 messages can be caused by bad sectors in the virtual memory paging file or a disk controller error. In extremely rare cases, depleted nonpaged pool resources can cause this error. If the first and third parameters are zero, the stack signature in the kernel stack is missing, an error that is typically caused by defective hardware. If the I/O status is 0xC0000185 and the paging file is on a SCSI disk, check for cabling and termination issues. An I/O status code of 0xC000009C or 0xC000016A indicates that the requested data could not be found. You can try to correct this by restarting the computer. Additionally, use ChkDsk to check the disk for problems.
• Another cause of Stop 0x77 messages is defective, malfunctioning, or failed memory hardware, such as memory modules, L2 SRAM cache, or video adapter RAM. If you added new hardware recently, remove and replace the hardware to determine whether it is causing or contributing to the problem. Run Windows Memory Diagnostics to determine whether the feature has failed.
• The problem might also be due to cracks, scratched traces, or defective features on the motherboard. If all else fails, take the system motherboard to a repair facility for diagnostic testing.
• Problems that cause Stop 0x77 messages can also cause Stop 0x7A messages. For more information about Stop 0x7A messages, see the following section, "Stop 0x7A or KERNEL_DATA_INPAGE_ERROR."
