What should I do if my VAIO computer becomes unstable (Windows does not start)?

• Try the suggestions below:

• Restore computer system files. [Details]
  Use the restore point that you created before your VAIO computer becomes unstable.

• Restore your VAIO computer from a system image backup if you have created the backup. Refer to Windows Help and Support for more information.
  Any file you have created or changed after you created the system image backup will not be restored. You need to back up such a file with VAIO Care Rescue. [Details]

• Use VAIO Hardware Diagnostics to identify problems on your VAIO computer.

• With the software, you can check if the computer hardware (a CPU, a memory module, and a built-in storage device) needs to be replaced. To start VAIO Hardware Diagnostics, click Tools and VAIO Hardware Diagnostics in VAIO Care Rescue.

• Follow the instructions in Recovering from the Recovery Area to recover your VAIO computer. [Details]

• If you have not backed up your data, be sure to make a backup copy of your valuable data using VAIO Care Rescue before recovering your VAIO computer. [Details]
  If you have a backup created with the Windows backup feature before your VAIO computer becomes unstable, but you have created or changed the file after that, back up such a file with VAIO Care Rescue.

• Recovering your VAIO computer will delete all the data on the built-in storage device.
