Bug check 0x00000077 (KERNEL_STACK_INPAGE_ERROR) means the system could not read kernel stack data from the paging file (pagefile.sys) into memory. This is similar to 0x7A (KERNEL_DATA_INPAGE_ERROR) but specifically for stack data. The error status code reveals the cause: 0xC000009C = bad disk block, 0xC000009D = unrecoverable disk error, 0xC000016A = disk not accessible. Fixes:
- Check the health of the drive containing pagefile.sys with CrystalDiskInfo,
- Delete and recreate the pagefile: System → Advanced → Performance → Virtual Memory → set to 'No paging file', reboot, set back to 'System managed', reboot,
- Check and reseat disk cables (SATA cables can work loose),
- Run memtest86 to rule out RAM,
- If disk is failing: back up immediately and replace.
