I am posting a summary checklist of general things you can do to solve this problem, and briefly discussing the three most common causes : malware, uncontrolled applications, and insufficient maintenance, because many readers write about their computer reacting slowly.
Perhaps the greatest contributor to a poorly performing computer is malware.
