Cold boot is a technical term referring to the process of starting a computer by turning it on after it has been powered off completely. However, there are also several other synonyms for this term, each describing the same action in slightly different ways. These alternate terms include "power-on reset," "hard reset," "system restart," "reboot," and "boot-up." Regardless of the term used, this process can help to resolve many computer-related issues, including freeze-ups, crashes, and other performance problems. By restarting the system completely, it clears out any lingering issues and ensures that the computer is running as smoothly as possible.
