Is there an easy way to diagnose what’s slowing down my PC?

Yes. There are plenty of online resources and software tools designed to help diagnose PC performance issues. Windows users can try using the built-in Performance Monitor or the Resource Monitor found in the Task Manager. Mac users can use the Activity Monitor to see which processes are consuming the most resources. You can also use third party system utilities such as CCleaner, Glary Utilities, and SlimCleaner Plus to detect, diagnose, and repair any issues that may be causing slowdowns.
