Troubleshooting Hardware Issues Flashcards
What are the symptoms of power issues in hardware?
• System fails to power on.
• Intermittent shutdowns or restarts.
What is the first step to troubleshoot power issues?
Check the power source to ensure the device is plugged into a functional outlet.
What should you check after ensuring the device is plugged into a functional outlet?
Inspect the power cables and verify that power supply cables and motherboard power connectors are secure.
How do you test the power supply unit (PSU)?
Use a PSU tester or multimeter to confirm voltage outputs (12V, 5V, and 3.3V DC).
What are the symptoms of POST issues?
• No display or system beeps during startup.
• Error messages or beep codes.
What should you do when you hear beep codes during POST?
Refer to the motherboard manual to interpret the beep codes (e.g., continuous beeps could indicate RAM failure).
What are the symptoms of crash screens like the Blue Screen of Death (BSOD)?
Unexpected crashes with error codes displayed (Windows BSOD).
What are common symptoms of cooling and overheating issues?
• System shuts down during intensive tasks.
• Fans run loudly or constantly.
What is the first step to troubleshoot cooling issues?
Inspect the cooling system, including CPU and GPU fans, heatsinks, and thermal paste.
How do you check for cooling issues related to airflow?
Ensure proper placement of fans for intake and exhaust, and clean dust from fans, vents, and heat sinks.
What are the symptoms of physical component damage?
Visible signs of damage like broken capacitors or bent pins.
What are the symptoms of performance issues in hardware?
Sluggish system response, applications freezing, or crashing.
What can cause inaccurate system date and time?
A dead CMOS battery can cause the system clock to reset.
What should you do if the power button does not work?
Check if the power button cable is properly connected to the motherboard.
How do you troubleshoot a faulty wall outlet?
Use a multimeter to check the voltage and test with another working device.
What could no beep codes during POST indicate?
Power supply issue or a faulty internal speaker.
What does one long continuous beep during POST indicate?
A memory issue, such as a faulty module or memory controller.
