Windows 7 sometimes fails to restore the session from hibernation which causes the computer to fail on startup and the keyboard and mouse stop responding. This is caused by a corrupt restore point and disabled USB Legacy setting in the BIOS.
- Restart computer and enter BIOS
- Find and enable USB Legacy Support for the keyboard and mouse
- Save the configuration and exit the BIOS.
- When the computer restarts and windows restoration point failure appears select 'Delete restoration point and boot system'
