"The previous system shutdown was unexpected" error

Hi Carlos,

Troubleshooting startup problems can be difficult because every PC is set up differently. Drivers, conflicts with other programs, malware, and memory can all cause startup problems. Startup repair can detect and fix problems that prevent your PC from starting.

Perform steps from the link mentioned below and see if it helps.

Windows hangs or freezes

Whenever powering up my system after it hibernated from sleep, I get an error message at boot stating that the system wasn't shut down nicely.

System event log says that "The previous system shutdown at <time> on <date> was unexpected".

The last event logged before the system powers off (logged at <time> + 10 seconds) is "The system is entering sleep. Sleep Reason: Hibernate from Sleep".

This started happening after the last Windows update. I don't get this error when I force the system to hibernate manually. Filesystem scan reports all ok.

Ideas?
