Dakota uses a power supply tester to examine the power supply on a friend's desktop computer that is exhibiting problems. The tester measured a 7 V reading from the +12 V output.Which devices are most likely to be affected by this deficiency? Select two.

Graphics cards Correct. Graphic cards draw the most power, they draw from the +12 V output. SATA Drives Correct. Some older SATA drives require 12 V.

Which of the following method is not typically used to keep a computer system cool?

Keeping the case open Correct. Keeping the case open is not a recommend long-term cooling solution. A closed case with fans placed in the proper location improves airflow to draw heat away from the system.

Your computer system loses power while you are working on a project for a very important client. When the computer restarts, you hear continuous short beeps coming from your computer, and the monitor is showing no signal.What do the beeps mean?

POST has failed, and you should research the BIOS beep codes. Correct. Research the BIOS type and beep codes. Continuous short beeps with an Award BIOS indicates a memory error; with an Intel BIOS it indicates a loose card or short.

While you are working on your computer, it shuts down unexpectedly, and you detect a burning smell. When you remove the case cover, you notice a distended capacitor. What can you do to fix this problem?

Replace the motherboard.

Sara is having a tough time finding the cause of a problem on a computer she is troubleshooting. She found a possible problem but is not sure if she is correct. In case she is wrong, Sara does not want to test her theory, because doing so might worsen the problem.What would you advise Sara to do?

Research the problem on the Internet. Correct. Sara should research the problem until she is sure of her theory. If she thinks it might cause a different problem, she must talk to the customer before testing her theory.

Sara works in the IT department for a large retail store. She has been testing a theory about why an error message keeps popping up on a coworker's computer when they try to start Windows. She has hit a wall and doesn't know where to look next. Sara feels very frustrated with the problem.What should Sara do to help work out the solution?

Take a break and come back later. Correct. If Sara is becoming frustrated, she can take a break, walk away, and start afresh. This is Rule 11 of troubleshooting strategies and is the best way to beat frustration. Walking away and giving herself a fresh start later will help her uncover events or steps that she may have overlooked.

Your laptop at home is exhibiting intermittent problems and you suspect it could be related to power.How can you verify the power adapter is supplying the proper voltage?

Use a multimeter. Place the red probe of the multimeter in the center of the DC connector and the black probe on the outside cylinder. Correct. But first set the multimeter to measure voltage in the 1 - 200 V DC range or similar.

Connect the drive to another computer and copy the data to another storage media.

You bought a new computer with two case fans that constantly run a little loud. However, right out of the box, you notice the system is exhibiting intermittent problems. You go into the BIOS and observe the CPU temperature is 100 degrees Fahrenheit (38 degrees Celsius). Which of the following best describes the thought process you should employ in your troubleshooting efforts?

Consider troubleshooting issues and possibilities that are not necessarily related to cooling. Correct. The CPU temperature gives no indication the problem is cooling related. Spend time troubleshooting issues that are not related to cooling.

Henry is having a problem with the electrical system on his current laptop. The battery for the laptop will not charge. Henry took the AC adapter and battery from another laptop that is known to work, and put them in his current laptop, but still the battery will not charge.What possible actions can Henry take to make his laptop usable? (Select all that apply.)

Henry can replace the laptop system board. Correct. The system board is not allowing the battery to charge and may need to be replaced. This is not a frequent problem but is a feasible one in the scenario. The system board controls when the battery charges, and that might be causing the problem. Also, the pins on the charging port may be broken and thus need to be replaced.' Henry can purchase a new laptop. Correct. This option would fix the problem by eliminating it. This is not a real solution as Henry is not repairing the laptop itself, However, in the end this might be the only way to fix the problem. Henry can use the laptop only when it's connected to the power using the AC adapter. Correct. This option is not ideal for Henry because he would need to plug the laptop into a power outlet at every location he used it; however, doing so would allow him to use his laptop.

When you verify a fix, you determine that the problem could have been prevented. What should you do to help the user avoid having the same problem again?

Instruct the user on how to prevent the problem. Correct. If you think the problem could have been prevented, the best option is to explain the cause of the problem to the user and how he might prevent this type of issue from occurring. For example, explaining that being especially careful about answering emails from unfamiliar people might help the user prevent malware from infiltrating his computer. This falls under step five of the troubleshooting strategies where you verify the fix and take preventive action.

William has been working on a problem with a computer at his company for several hours and still can't ascertain the problem. The computer will not turn on, and William has tried everything he can think of to fix the computer. He has replaced the power cord, the power supply, and even the power strip the computer is plugged into. William decides that it must be the motherboard and takes the computer to his shop to replace the motherboard on the computer. When he plugs the computer in, it turns on. The problem was not the computer-someone had turned off the switch for the wall outlet that the power strip was plugged into.At which step in the troubleshooting process could William have discovered this problem? (Select all that apply.)

Interview the user and up backup data Correct. William might have found this problem if he had asked about environmental changes to the area where the computer is used. Examine the system and making a best guess Correct. The problem might have been discovered if William had researched the power structure of the building. Test the theory to determine cause Correct. When William was testing his theory, he might have discovered that the computer was working properly if he had taken the power supply and tried it somewhere other than at the desk.

Thomas came into work this morning and turned on his computer but nothing happened. He immediately called the help desk, and you were sent to fix his computer. While talking with Thomas about his computer, you find out that when he turns on the computer, he has lights and fans, but nothing else happens. He also tells you that the four memory modules were recently upgraded. Besides the memory, nothing else has been added or changed. You decide to try to re-create the problem, and when you turn on the computer, there are lights and fans, but no beeps and no video. You notice that the keyboard light does not come on.What can you determine about the problem with Thomas's computer? (Select all that apply.)

Motherboard has failed. Correct. A scenario in which the computer is not running POST could indicate that the motherboard has gone bad. Failure of the motherboard will be indicated by no beep code, no video, and no Num Lock light on the keyboard. Processor has gone bad or is not seated properly. Correct. The computer needs a processor to run POST. If the processor can't execute the instructions to run POST, then lights and fans will run, but there will be no video or POST error beep codes.

When you turn on your computer for the day, you notice lights and fans but no beeps and no video. The Num Lock light does not come on.What might be the problem with your computer? (Select all that apply.)

Motherboard has failed. Correct. The fact that the computer is not running POST could indicate that the motherboard has gone bad. For a computer to run POST, you need a processor, RAM, and the motherboard code. When a computer fails to give any indication of a problem, you should check the Num Lock key on the keyboard. If the Num Lock light is not on, then POST has not run. You need to test each component to determine which one is not working properly. Processor has failed or is not seated properly. Correct. The fact that the computer is not running POST could indicate that the processor failed or is not seated properly. For a computer to run POST, it needs a processor, RAM, and the motherboard code. When a computer fails to give any indication of a problem, you should check the Num Lock key on the keyboard. If the Num Lock light is not on, then POST has not run. You will need to test each component to determine which one is not working properly. RAM is not working properly. Correct. If all the RAM has failed, then POST will not run on your computer. For a computer to run POST, it needs a processor, RAM, and the motherboard code. When a computer fails to give any indication of a problem, you should check the Num Lock key on the keyboard. If the Num Lock light is not on, then POST has not run. You will need to test each component to see which one is not working properly.

You have an eight-year-old computer with all the original components still in place. The power supply fan seems to be going bad, so you start troubleshooting. You replace the power supply, but the fan continues to have the same problem. You then disconnect all the other components except the motherboard. Only under this condition does the fan works as expected.Which of the following is most likely to be true?

One of the other components was causing a short and drawing too much power. Correct. Since the fan works without a problem when only the motherboard is connected to power, the problem is likely caused by one of the other components inducing a short when connected. To resolve, connect one component at a time until the faulty device is identified.

Lin is booting up his computer. Sometimes during the boot process, the computer will shut down, but more often than not it will reboot on its own or simply freeze. He thinks the problem could be due to an intermittent undervoltage problem with the power supply, so he uses a power supply tester. The test shows that the power supply is functioning properly.What should Lin check next in the troubleshooting process?

RAM Correct. RAM is the simplest thing Lin can check in this troubleshooting process. To reseat RAM, Lin pulls outward on the supporting arms that secures the memory module in the DIMM slot, removes the memory, and reseats it. He pushes down gently but firmly on both ends of the memory stick until the supporting arms latch it in place. Faulty RAM will typically not cause the computer to shutdown but troubleshooting this component can at least rule it out as being the problem.

George is involved with a project at work. Over the last few weeks, he has noticed a gradual but significant degradation in performance when running his AutoCAD program. He calls the technician and asks him to check his computer. The technician tells George to reboot the computer and asks George how much RAM was detected. The amount of RAM reported is exactly as expected.What hardware could be causing this problem? Select two.

RAM Correct. The most common cause of RAM not being detected is a memory module that is not seated properly. The technician should reseat all the RAM and see if that fixes the problem. If not, then he should check each RAM module individually by placing only one module in a RAM slot and restarting the system to see if a particular RAM module has gone bad. Motherboard Correct. The motherboard DIMM slot could also be causing this problem. The best way to determine whether the motherboard is the problem is to remove and replace all the RAM, one module at a time. This process tests each slot to see whether a particular memory slot is the issue.

You notice that your computer is running slow and decide to reboot the computer to see if that will fix the problem. During the reboot, you notice that the amount of RAM shown during the RAM count is not the same as it was the day before.What might cause this problem?

RAM module has become unseated. Correct. The most common cause of RAM not being detected is a memory module that is not seated properly. You should reseat all the RAM and see if that fixes the problem. If that does not fix the problem, remove all the RAM, and reinstall each module individually to see if a particular RAM module is not working properly.

Abdel, an electrician, does not know much about computers so he orders a custom computer with a 1000 W power supply. However, the maximum wattage the system needs is 500 W.Which of the following statements are true? Select two.

The 1000 W power supply will last longer than, for example, a 750 W power supply. Correct. A 1000 W power supply operating at 500 W will last longer because the load is only 50% of its capacity so it is not stressed. It will also run cooler. The power supply will only deliver up to 500 W of power and operate very efficiently. Correct. The power supply will only deliver as much power as is being requested so it will only deliver 500 W of power in a very efficient manner.

Larry got a new job and moved from New York to Hawaii. After a couple of weeks, he notices that occasionally, the time, date, and time zone are all wrong. He has no idea what is happening and believes it is because he moved to a different time zone.What is likely to be causing the problem? BIOS is corrupt and needs to be flashed.(X) Incorrect. Larry's computer is turning on without other issues, so the BIOS is not the problem. If the BIOS was corrupt, the power-on self-test would fail. The problem is a failing CMOS battery, but it will still allow the computer to pass POST. The internal clock rate is unstable and drifting. The motherboard is degraded and about to fail. The CMOS battery is failing and needs to be replaced. Larry didn't set the time on his computer after he moved.

The CMOS battery is failing and needs to be replaced.

Li, a helpdesk technician, is troubleshooting a system. Based on experience, Li has narrowed down the problem and believes it is related to either the motherboard, processor, or RAM.Which symptoms would have allowed Li to narrow down the problem? Select three.

The system reports less memory than is installed. Correct. When the system reports less memory than is installed it could indicate faulty RAM or RAM that is not properly seated. Ensure all memory modules are properly seated, use the Memory Diagnostic Tool, and/or replace all memory modules as needed. The system begins to boot but then powers down. Correct. This could be due to overheating. Ensure all fans are operational, particularly the CPU fan. If the problem persists, try applying fresh thermal paste. An error message is displayed while booting. Correct. Error messages displayed during the boot cycle should be investigated. Search online for information about the error message. Pay special attention to results that relate to the motherboard or processor.

You decide to add three new hard drives to your computer so that you can increase the amount of storage on it. When you install the hard drives, you find enough SATA connections on the motherboard, but it is short one SATA power connector.What is the easiest way to add a SATA power connector to the system?

Use a Molex to SATA power adapter. Correct. You can use a Molex to SATA power adapter to supply power to the SATA hard drive.

James added a new video card and needs to get a power supply that will have enough power to run the new card. When researching the new power supply, what feature does James need to look for to make sure he has enough power to run his computer with the new video card?

Wattage Correct. Wattage is the amount of power or total output under maximum load. Video cards draw the most power in a system, and it is important to pay attention to the +12V rating.

Your customer wants to build a new computer and needs to make sure he orders the correct power supply for his machine.What should you tell him to check to make sure he orders the correct power supply? (Select all that apply.)

Wattage requirements Correct. Wattage requirements are the total amount of wattage or power needed based on the number of devices connected to the system. If the customer doesn't have enough wattage for his computer, the computer will not turn on. Additionally, if he has a power supply with too much wattage, he will have spent extra money unnecessarily. The power supply should be capable of delivering at least 30% more wattage (power) than the maximum power the system is capable of drawing. Form factor Correct. Because the customer must be able to mount the power supply to the case, form factor is an important consideration. If he purchases the wrong form factor, the power supply will not fit, and he will have to return the power supply and purchase the correct form factor. Number of hard drives Correct. The customer will need to make sure he has a SATA power connector for each hard drive, from the power supply. If he doesn't have enough SATA power connections, he will not be able to install all the hard drives that he plans to use in his computer. Video requirements Correct. If he is ordering a video card, he will need to make sure he has the power connector required for the video card. He will need either a 6-pin or an 8-pin video card power connector. There is also a possibility that he will need two 6-pin connectors. If he decides to install multiple video cards, he will need a sufficient number of 6-pin or 8-pin power connectors for each video card power connector.
