Hardware Troubleshooting

Correct Answer: Blocked or dirty cooling vents

Overheating issues are typically caused by blocked or dirty cooling vents, as it prevents the efficient removal of heat. The other options might cause other types of performance issues but are not related to overheating.

Correct Answer: Memory failure

Repetitive long beeps during Power-On Self-Test (POST) usually indicate a hardware failure, and beep codes can vary depending on the motherboard BIOS manufacturer. However, a common interpretation for long continuous beeps is a memory failure. This could mean that the system's RAM is not functioning correctly, is not seated properly, or is absent. As for the other options: A graphics card disconnection typically would not cause long, continuous beeps; it might cause different beep codes or no signal to the monitor. Processor overheating is usually not signaled by long continuous beeps during POST; instead, the system might shut down to prevent damage or display a warning message. Lastly, a faulty power supply unit typically prevents the system from powering on at all, rather than causing long beeps, unless the motherboard is still receiving some power but not enough to complete POST.

Correct Answer: Loose or faulty hard drive connections

The 'No boot device found' error usually indicates that the computer cannot access the hard drive or that the hard drive is not configured correctly. This can be caused by loose or faulty connections. Other options are less likely to cause this specific error.
