A computer that does not start, stops responding, or began to misbehave after an update: stop codes and crash logs, safe mode, driver rollback, and the built-in repair tools you run to find out what changed.
Common failure modes
- An update installed and the machine unstable ever since
- A driver rolled forward with no record of the version that worked
- A stop code seen once, cleared, and never written down
- A startup fault never isolated, because safe mode was never tried
- A repair started before any backup existed
Procedures
No procedure is published in this section yet. New procedures are added as their specifications can be traced to a manufacturer or government source.
Where this stops
Component-level hardware repair and data recovery from a failing disk need a specialist. A page that reaches that point says so and stops.
