After continuous morning use, a computer suddenly reboots without the intervention of the user. What are the two most likely hardware parts that could cause this problem? (Choose two.)

When a computer reboots suddenly without user intervention, particularly after being used for an extended period, it often points to issues related to hardware stability or overheating. The two hardware components most likely to cause this problem are:

1. Power Supply: A faulty or inadequate power supply can cause the computer to reboot unexpectedly. If the power supply is unable to deliver consistent power due to age, damage, or being underpowered for the system’s requirements, it can lead to sudden reboots. This is especially likely if the computer has been under continuous use, placing more demand on the power supply.
2. CPU (Central Processing Unit): The CPU is another common culprit in cases of unexpected reboots, often due to overheating. Continuous use can cause the CPU temperature to rise, especially if the cooling system (like fans or heat sinks) is not working effectively or if thermal paste has degraded. When the CPU overheats, most systems are designed to reboot automatically to prevent damage.

While other components like the hard drive, RAID (Redundant Array of Independent Disks), BIOS (Basic Input/Output System), and wireless NIC (Network Interface Controller) can potentially cause issues, they are less likely to be the cause of sudden reboots compared to the power supply and CPU. A failing hard drive or RAID issues would more commonly result in system freezes or error messages, BIOS issues would typically prevent the computer from booting up correctly in the first place, and a faulty wireless NIC is more likely to cause network-related problems rather than a system reboot.
