What is the first step in the CompTIA six-step troubleshooting methodology?

Identify the problem - gather information, duplicate issue, question users, identify symptoms

True or False: When multiple problems exist, you should address them all simultaneously.

False. Address multiple problems individually, not all at once to avoid confusion.

A computer shows no power, no lights, no fans spinning. What component should you check first?

Power supply unit (PSU) and power cable connections

What does continuous beeping during startup typically indicate?

RAM failure or improperly seated memory modules

Fill in the blank: POST stands for _____.

Power-On Self-Test

Which diagnostic tool runs outside the operating system to test RAM?

Memtest86+

A hard drive makes clicking sounds. What does this indicate?

Mechanical head failure - immediate data recovery needed

What temperature range is safe for CPU operation under load?

Under 80°C

Multiple Choice: What causes a laptop screen to be extremely dim but still visible?
A) Failed GPU
B) Bad RAM
C) Backlight failure
D) Motherboard issue

C) Backlight failure

True or False: S.M.A.R.T. monitoring can provide early warnings of drive failure.

True. S.M.A.R.T. status shows early warnings before complete drive failure.

What should you do immediately if a laptop battery appears swollen?

Replace the battery immediately - it's a fire hazard

A laser printer produces smudged toner that rubs off easily. What component needs replacement?

Fuser assembly

Fill in the blank: To clear CMOS settings, remove the _____ battery for 5-10 minutes.

CR2032

What is the most common cause of smartphone charging issues requiring cable positioning?

Debris and lint buildup in the charging port

Multiple Choice: One long beep followed by two short beeps indicates:
A) RAM failure
B) Video card issue
C) CPU failure
D) PSU failure

B) Video card issue

Why should you test individual RAM sticks in different slots?

To isolate whether the problem is a bad stick or bad slot

What happens when a computer reaches thermal shutdown temperature (90-100°C)?

System shuts down automatically to prevent permanent component damage

True or False: You should replace the motherboard first when troubleshooting no display issues.

False. Check RAM seating first - it's more common and less expensive.

Which Windows command checks for file system errors and bad sectors?

CHKDSK with /F and /R parameters

Fill in the blank: The _____ handles touch input while the LCD displays the image.

Digitizer

What causes faded prints on a laser printer even with new toner?

Worn or scratched imaging drum

How long should you press the power button to discharge residual power?

5 seconds

Multiple Choice: Random shutdowns during gaming but not web browsing indicate:
A) RAM failure
B) Overheating
C) PSU failure
D) Software corruption

B) Overheating

What tool should you use to clean smartphone charging ports safely?

Compressed air and wooden/plastic toothpick (non-metallic tools)

True or False: Mixing DDR3 and DDR4 RAM modules is acceptable for compatibility.

False. DDR3 and DDR4 are incompatible and cannot be mixed.

When should you escalate a troubleshooting issue according to the methodology?

During step 3 when testing theory if you cannot determine the cause

What voltage switch setting error commonly causes PSU failure symptoms?

Incorrect 110V vs 220V switch position for your region

Fill in the blank: The _____ assembly in laser printers heats toner to 180-200°C.

Fuser

Why should you photograph PSU connections before disconnecting them?

For reference when reconnecting cables to proper locations

Multiple Choice: No POST with no beep codes most commonly indicates:
A) PSU failure
B) RAM issue
C) Monitor failure
D) Hard drive failure

B) RAM issue

What is the proper sequence for testing smartphone charging problems?

Test known-good cable/adapter, then inspect and clean charging port

True or False: Thermal paste should be reapplied when CPU temperatures rise significantly over time.

True. Old thermal paste dries out and loses effectiveness.

Which step comes after implementing a solution in troubleshooting methodology?

Verify full system functionality and implement preventive measures

What indicates mechanical hard drive head failure requiring immediate backup?

Clicking or grinding noises from the drive

Fill in the blank: Safe GPU temperature under load is typically under _____°C.
