Q

You are troubleshooting a Windows-based desktop computer that is experiencing unexpected shutdowns. Which of the following would be a good next step to resolve the issue? (Choose two.)

A) Replace the motherboard, CPU, and RAM to see if it resolves the problem.
B) Replace the RAM to see if it resolves the problem.
C) Reinstall Windows to see if it resolves the problem.
D) Replace the CPU to see if it resolves the problem.

A

B, D. Intermittent shutdowns are hard to troubleshoot but are most likely hardware related. When troubleshooting, always make one change at a time to try to resolve the issue. Replacing the RAM or the CPU to see if it resolves the problem could be a good next step, but replacing three components at once is too many changes unless you have specific reason to believe it is all three. Reinstalling Windows is probably overkill as well. Narrow down the issue before implementing sweeping solutions such as that.

Q

When a desktop computer boots up, there is no video on the LCD monitor, just a blank screen. The system makes one beep when it powers on, and air is coming out of the case fan. What is the most likely cause of the problem?

A) The motherboard has failed.
B) The video card has failed.
C) The monitor is disconnected.
D) The CPU or RAM has failed.

A

The monitor is disconnected.
When troubleshooting, always question the obvious. In this case, the system beeps once, which is usually a signal from the BIOS that POST completed successfully and air is coming from the system fan. All of that appears to be normal. Check to see that the monitor is connected properly to the desktop computer and that it’s receiving power.

Q

You are training a class of new technicians on troubleshooting motherboard issues. Which of the following are issues most likely caused by a failing CMOS battery? (Choose two.)

A) BIOS time and setting resets
B) Attempts to boot to the incorrect device
C) Intermittent device failure
D) BSOD/pinwheel errors

A

A) BIOS time and setting resets
B) Attempts to boot to the incorrect device

A, B. When the system is powered off, BIOS settings on a motherboard are maintained by the CMOS battery. If the battery fails, the system will likely forget the BIOS time and date settings and the boot order configuration. Replacing the CMOS battery will resolve the issue.

Q

A technician who has been troubleshooting a computer tells you that the system is having problems with overheating. Which component is most likely to cause this issue?

Power supply, Motherboard, CPU, RAM

A

CPU.
The processor runs the hottest of all computer components and is the most likely to overheat. Motherboards and RAM don’t generate a lot of heat. Power supplies most often have fans to help dissipate heat, and they don’t run as hot as CPUs.

Q

You turn on a desktop computer and it fails to boot. You hear a rhythmic ticking coming from inside the case. What is most likely the problem?

A) Failed hard drive
B) Failed motherboard
C) Failed CPU
D) Failed RAM
E) A bomb

A

Failed hard drive.
Only components with moving parts can make ticking or clicking noises. (Bombs can too, but hopefully you recognized that as a fake answer!) This question assumes that the hard drive is an HDD and not an SSD, but none of the other components would make a ticking noise.

Q

When you turn on a desktop computer, you hear a loud squealing noise coming from inside the case. Which components are potential culprits for making the noise? (Choose all that apply.)

A) CPU fan
B) Power supply fan
C) HDD
D) SSD
E) CPU
F) RAM

A

A, B, C. Only components with moving parts can make ticking, clicking, or squealing noises. It’s probably a fan of some sort (such as the CPU fan or power supply fan), or it could be a conventional hard drive. SSDs, CPUs, and RAM do not have moving parts and therefore could not be causing this problem.

Q

A user complains of smoke and a foul odor coming from their desktop computer, so they shut it down. Which component is most likely causing the problem?

A) Power supply
B) RAM
C) CPU
D) Motherboard

A

Power supply.
Smoke and foul odors such as burning smells are not normal for computers! The most likely component causing the problem is the power supply. With the system off, open the computer case (not the power supply case!) to examine the inside for possible physical damage.

Q

A Windows user complains that their computer keeps crashing. What is the proprietary crash screen they are most likely seeing?

A) Stop sign
B) Pinwheel
C) BSOD
D) Black screen

A

BSOD.
When Windows‐based systems crash, as can happen due to a memory, CPU, or motherboard problem, they will most likely display a Blue Screen of Death (BSOD). The good news is that the BSOD can often provide useful information, such as an error code, to help troubleshoot the problem. There is no stop sign proprietary crash screen, and the pinwheel is used in macOS. A black screen may indicate a system crash but is not proprietary to one operating system.
