While a user is working on a spreadsheet, the computer reboots. What are two components that could cause this issue? (Choose two.)

In the scenario where a computer reboots unexpectedly while a user is working on a spreadsheet, the two components most likely to cause this issue are the CPU and Power Supply. Here’s an explanation for these choices and why the other options are less likely:

1. CPU (Central Processing Unit): The CPU is critical for processing all the tasks on a computer. If the CPU is overheating, it could cause the computer to reboot unexpectedly as a protective measure. Additionally, other CPU issues like voltage irregularities or physical damage can also lead to sudden reboots.
2. Power Supply: An unstable or failing power supply can cause the computer to reboot without warning. Issues like power surges, inadequate power output, or a failing power supply unit can lead to sudden loss of power or power fluctuations, resulting in the computer rebooting.

Now, let’s discuss why the other options are less likely:

• ROM (Read-Only Memory): ROM, which typically contains firmware like the BIOS, is not usually a direct cause of random reboots. Issues with ROM would more likely lead to boot problems or errors in firmware execution, rather than unexpected reboots during regular operation.
• BIOS (Basic Input/Output System): While BIOS issues can cause startup problems, they are less likely to cause a computer to reboot randomly during regular operations like working on a spreadsheet.
• RAID (Redundant Array of Independent Disks): RAID is a data storage technology used for redundancy and performance. Problems with RAID arrays generally lead to data access or storage issues and are unlikely to cause sudden reboots unless the system’s primary disk is affected. Even then, it’s a less common cause compared to CPU or power supply issues.
• Wireless NIC (Network Interface Controller): A wireless NIC handles network connections and is unlikely to cause the system to reboot. Issues with a wireless NIC would more commonly result in network connectivity problems.

In summary, the CPU and Power Supply are the most likely culprits behind a computer rebooting unexpectedly while in use, due to their direct roles in processing and power management.
