A user has contacted you with a computer problem and cannot provide much information on what happened. The user seems like this may be their first time using a computer. Your first action in responding to the issue should be:
Restart the PC in safe mode and tell the user to report if the issue repeats.
The Event Viewer typically is a good place to start troubleshooting issues, as many errors are listed here.
Event Viewer is a component of Microsoft's Windows NT operating system that lets administrators and users view the event logs on a local or remote machine. Applications and operating-system components can use this centralized log service to report events that have taken place, such as a failure to start a component or to complete an action. In Windows Vista, Microsoft overhauled the event system.Due to the Event Viewer's routine reporting of minor start-up and processing errors (which do not, in fact, harm or damage the computer), the software is frequently used by technical support scammers to trick the victim into thinking that their computer contains critical errors requiring immediate technical support. An example is the "Administrative Events" field under "Custom Views" which can have over a thousand errors or warnings logged over a month's time.
