0x0000007A – KERNEL_DATA_INPAGE_ERROR

Kernel data could not be loaded.

Record the stop code. Avoid speculative repairs after repeated crashes or drive errors. Contact IT for work computers.

Write down the complete error and whether important files are still readable.
If you hear clicking noises, repeated reading errors or irreplaceable data: stop using it and seek professional advice about data recovery. No formatting, defragmentation or repair with chkdsk without a diagnosis.
If no physical damage is suspected, create a verified backup first; Plan further driver, cable or file system diagnostics with specialist help.

Test after each step and stop when the issue is solved. Checkmarks are not permanently saved.
