Computer diagnostics refers to the process of identifying and troubleshooting issues within a computer system. This can involve using specialized software tools to analyze hardware and software components, helping to pinpoint problems such as system crashes, slow performance, or connectivity issues. The diagnostics process often includes running tests on hardware components like the hard drive, RAM, and CPU, as well as checking for software conflicts or outdated drivers. By systematically evaluating these elements, technicians can determine the root cause of a problem and recommend appropriate solutions to restore optimal functionality.
