Q3 ICT Periodical Test

A computer fails to power on, and there are no LED lights or fan movement. What should be the first step in diagnosing the PSU?

• Check if the power cable is properly connected and test with another outlet

• Remove all peripherals and try again

• Replace the motherboard

• Test the PSU with a multimeter

A computer randomly shuts down even though it has sufficient cooling. What PSU-related issue could cause this problem?

• Overvoltage protection is turned off

• The hard drive is full

• The motherboard is faulty

• The PSU is delivering insufficient power

After replacing a PSU, a technician finds that the system still does not boot, but the PSU fan is spinning. What should be checked next?

• The CPU temperature

• The graphics card driver

• The motherboard connections and power button wiring

• The operating system

Which of the following tools is commonly used to test a PSU's voltage output?

• Multimeter

• Oscilloscope

• Screwdriver

When using a paperclip test to check a PSU, what indicates that the PSU is functional?

• The computer turns on

• The motherboard beeps

• The PSU fan starts spinning

• The RAM LEDs light up

A computer shows signs of power fluctuation, such as random restarts and component failure. What should a technician consider before replacing the PSU?

• Whether the monitor displays a stable image

• Whether the power supply cables are properly connected

• Whether the power supply wattage meets the system's requirements

A technician is troubleshooting a PSU that appears dead but still receives power. What should be the next logical step?

• Check the PSU using a multimeter or power supply tester

• Disassemble the PSU and repair internal circuits

• Format the hard drive

• Replace the CPU

A PSU has been tested and delivers unstable voltage outputs. What is the best course of action?

• Adjust the voltage manually in BIOS

• Continue using it, as fluctuations are normal

• Ignore it if the computer is still running

• Replace the PSU immediately to prevent damage to other components

What is the purpose of creating a bootable USB drive?

• To improve system performance

• To install or repair an operating system
