Diagnosing problems within a network or a computer requires a special and versatile toolbox for the IT specialist. This 9-video series outlines many popular troubleshooting tools and practical strategies needed to quickly isolate all kinds of problems, regardless of platform, and resolve them, to help restore normal working conditions efficiently and quickly. Various process checklists are invaluable—the five-step system checklist, the six-step analyzing systems, the seven-step remediation of malware, all discussed here. Is the problem widespread or limited to one machine? Has anything significant been installed recently—hardware or software? Are users plagued by popups, spam, slow bootups, or slow performance? Do specific security issues need addressing? Is a Web-based email application (Hotmail, Yahoo, G-mail accounts) involved? If malware is suspected or discovered, the system is often infected; one machine or many may need to be rebooted, restarted, and cleaned—and antivirus or antimalware installed. Learn what to do and when to do it, from rolling back updates to restarting service. Course helps prepare for CompTIA+ certification exam 220-1002.
