Troubleshoot Windows problems. Windows has a number of troubleshooters that can save you time and headaches if you encounter a problem. Try these before you hire a computer expert.
To get at them, open Control Panel, click “System and Security”, and then under that select “Find and Fix problems”. You will see a list of troubleshooters. To see them all, select “View All” in the sidebar.
These troubleshooters are not a cure-all for every problem, but they are a good place to start and may just do the trick.
