If your pc is shutting down unexpectedly while you work on it, ask yourself these questions before doing anything else:

• Did I install any new program recently?
• Did I make any changes to the Windows settings recently?
• Did I install any new Windows updates?
• When was the last time I scheduled a registry scan?

All of them—installation of a new program or latest Windows updates, a change made to the Windows settings, and a corrupt, cluttered registry—can cause Windows to shut down unexpectedly.

If the first three are causing the issue, restore Windows to a time when abrupt, unplanned shutdowns were not occurring. To do this, perform the steps listed below:

1. Click the Windows logo
2. Type “system restore” in the Start Search box
3. Press Enter
4. Select either Recommended restore or Choose a different restore point
5. Click the Next button
6. Click the Finish button if you selected the Recommended restore option. If you choose the 2^nd option, select a restore point from the list displayed in the next screen, click Next, and then the Finish button

If the cause is a corrupt registry, run a registry scan using an advanced registry cleaner to fix the issue.
