Suppose you have observed that your system is performing more slowly than usual. It also takes much longer just to show the login screen. Applications are taking longer to load; switching among tasks is also taking longer and may even cause some applications to crash.

• Which system resources are likely to be at the root of the problem?
• Can there also be a security issue? If so, then what actions should you consider?
• Can there be failing hardware components? If so, then what actions should you consider?
• Discuss how you can use system tools, such as the Task Manager, to help identify and troubleshoot these problems.
