Correct Answer: Loose USB header connections on the motherboard

Loose USB header connections on the motherboard are the most likely cause of random USB device disconnections. If the USB headers are not properly seated or have become loose over time, it can lead to intermittent connectivity issues with USB devices. Overheating RAM modules, an underpowered GPU, or slower fan speeds would not directly cause USB device disconnections, as they are not directly related to the USB subsystem of the computer.

Correct Answer: Test each RAM module individually in each slot

To verify if the RAM slots are faulty, the best troubleshooting step is to test each RAM module individually in each slot. This will help isolate whether the issue is with a specific RAM module or with the RAM slots on the motherboard. By testing each module one at a time in different slots, you can determine if a particular slot is causing the problem or if a RAM module is defective. Cleaning the RAM heat spreader will not help diagnose slot issues, replacing the motherboard is premature without first testing the RAM modules and slots, and updating the BIOS is unrelated to diagnosing potential RAM slot problems.

Correct Answer: Look up the error code in the motherboard manual

The best course of action when encountering a motherboard error code during boot is to consult the motherboard manual. The manual will contain a list of error codes and their corresponding meanings, which can help diagnose the issue. Resetting the computer without understanding the error code may not resolve the underlying problem and could potentially cause further damage. Updating the BIOS is not always necessary and should only be done if specified in the manual or by the manufacturer. Unplugging SATA devices arbitrarily may not address the root cause of the error and could lead to data loss or other issues. By looking up the specific error code, Tom can identify the problem and take appropriate steps to resolve it.
