What is a primary benefit of preventive maintenance on a PC?
- It enhances the troubleshooting processes.
- It simplifies PC use for the end user.
- It extends the life of the components.
- It assists the user in software development.
Preventive maintenance helps reduce software and hardware problems by preventing undue wear on components, thereby extending the life of the components. It also assists in identifying failed components that require replacement, such as cooling fans.
Which task should be performed on a hard drive as part of a preventive maintenance plan?
- Ensure cables are firmly connected.
- Ensure the disk spins freely.
- Blow out the inside of the drive with compressed air to remove dust.
- Clean the read and write heads with a cotton swab.
Storage device problems are often related to loose or incorrect cable connections.
After a problem is identified, what is the next step for the troubleshooter?
- Implement a solution.
- Verify the solution.
- Document the findings.
- Determine the exact cause.
- Establish a theory of probable causes.
The steps of the troubleshooting process.
Step 1. Identify the problem.
Step 2. Establish a theory of probable cause.
Step 3. Test the theory to determine the cause.
Step 4. Establish a plan of action to resolve the problem and implement the solution.
Step 5. Verify full system functionality and, if applicable, implement preventive measures.
Step 6. Document findings, actions, and outcomes.
Which procedure is recommended when cleaning inside a computer?
- Hold the CPU fan to prevent it from spinning and blow it with compressed air.
- Remove the CPU before cleaning.
- Invert the can of compressed air while spraying.
- Clean the hard drive heads with a cotton swab.
Hold the fan blades in place when you clean the inside of the computer with compressed air to prevent over-spinning the rotor or moving the fan in the wrong direction.
A user has just upgraded the CPU in a PC. After powering on, the computer boots but does not display the correct information about the new CPU while booting. What is the most likely cause of the problem?
- The operating system needs to be upgraded.
- The CPU needs to be overclocked for it to show up correctly.
- The motherboard has incorrect BIOS settings.
- More RAM needs to be added to support the faster CPU.
Some CPU settings such as speed and voltage can be changed through the system BIOS.
An employee mentions that opening a large document file is taking longer than usual. The desktop support technician suspects that there might be a fault in the hard disk. What should the technician do next?
- Replace the hard disk with a new one to pinpoint the exact problem.
- Perform the disk cleanup procedure.
- Contact a data recovery company for service.
- Back up the user data from the workstation.
Always perform a backup before beginning any troubleshooting.
What is the best way to determine if a CPU fan is spinning properly?
- Listen for the sound of the fan spinning when the power is on.
- Spray compressed air on the fan to make the blades spin.
- Spin the blades of the fan quickly with a finger.
- Visually inspect the fan when the power is on to ensure it is spinning.
Spinning the fan blades with the power off, especially by using compressed air, can damage the fan. The best way to ensure the fan is working is to visually inspect it with the power on.
Which cleaning tool should be used to remove dust from components inside a computer case?
- cotton swabs
- damp cloth
- compressed air
To remove dust inside a computer, use a can of compressed air.
What is a symptom of a failing power supply?
- The display has only a blinking cursor.
- The computer displays a POST error code.
- The power cord will not attach properly to either the power supply or wall outlet or both.
- The computer sometimes does not turn on.
A failing power supply could also cause a computer to reboot unexpectedly. If the power cord does not attach properly, then it is likely that the wrong type of power cord is being used.
A user has noticed that the hard drive LED on the front of the computer has stopped working. However, the computer seems to be functioning normally. What is the most likely cause of the problem?
- The motherboard BIOS needs to be updated.
- The power supply is not providing enough voltage to the motherboard.
- The hard drive data cable is malfunctioning.
- The hard drive LED cable has come loose from the motherboard.
Each light on the front of the case is powered by the motherboard through a cable that attaches somewhere on the board. If this cable comes loose, a particular light on the front of the case will not work.
An employee reports that the output of a workstation display is distorted. The technician checks the manufacturer website and downloads the latest version of the video driver. After the video driver is installed, what should the technician do next?
- Move the display card to another slot to see if the video performs better.
- Open a video editing application to verify the video performance.
- Schedule the next system checkup with the employee.
- Log the previous and current version numbers of the video driver.
After the repairs have been completed, continue the troubleshooting process by verifying full system functionality.
During what step in the troubleshooting process does the technician demonstrate to the customer how the solution corrected the problem?
- Verify full system functionality.
- Establish a plan of action to resolve the problem.
- Establish a theory of probable cause.
- Document the findings, actions, and outcomes.
Once all repairs have been made, the last step of the troubleshooting process is to verify to the customer the problem and the solutions and demonstrate how the solution corrected the problem.
A technician helps a customer to add a new 2 GB RAM module to a workstation that currently has one 2 GB RAM module installed. Three empty RAM slots are available. However, only 2 GB of RAM is reported by the BIOS after the new RAM module is added. What are two procedures that the technician should perform to pinpoint or solve the problem? (Choose two.)
- Make sure the new RAM module is seated properly.
- Upgrade the operating system to Windows 7 to support more RAM.
- Test the new RAM module on another workstation.
- Replace with two 1 GB RAM modules.
- Check the manufacturer website for a BIOS patch.
RAM problems are often caused by faulty RAM modules, loosely seated modules, an inadequate amount of RAM, and compatibility issues.
In which step of the troubleshooting process would a technician have to do more research on the Internet or within the computer manual in order to solve a problem?
- Document findings, actions, and outcomes.
- Test the theory to determine the cause.
- Verify full system functionality and, if applicable, implement preventive measures.
- Establish a plan of action to resolve the problem and implement the solution.
- Identify the problem.
Once the cause of the problem is determined, a technician should research possible solutions, sometimes by visiting various web sites and consulting with manuals.
What component is most suspect if a burning electronics smell is evident?
- RAM module
- power supply
- hard drive
A burning electronics smell is often detected when a power supply is overloaded and damaged.
What method should be used by a technician to determine the exact cause of a problem?
- test theories of probable cause all at the same time
- start with most complex and most difficult probable causes to eliminate
- start with what the customer thinks is the problem
- start and eliminate the quickest and easiest probable causes
A technician should seek to determine the exact cause of a computer problem by testing theories of probable cause one at a time, beginning with the quickest and easiest to eliminate.
