Explanation

Random, unpredictable reboots are classically caused by two hardware components: the power supply unit (PSU) and RAM. A failing PSU delivers unstable or insufficient voltage, causing the system to reboot spontaneously. Faulty or incorrectly seated RAM causes memory errors that trigger sudden crashes and reboots. These two are the statistically most common hardware causes of random reboots and should always be checked first. The CMOS battery causes BIOS setting resets and clock issues, not reboots. Video card and optical drive failures typically produce display artifacts or read errors, not random system restarts.
