This document discusses troubleshooting computer issues. It covers three main areas of troubleshooting: hardware, software, and operating systems. Hardware troubleshooting involves issues with physical components like the motherboard, RAM, or hard drive. Software issues relate to problems with specific programs, like error messages or slow performance. Operating system troubleshooting looks at problems with the core OS, such as unexpected restarts or the system stopping responsiveness. The document provides examples of common issues that fall within each of these three troubleshooting categories.
