Billy complains that his computer is giving excessive error messages, the file names and folder names are garbled, and there is an odd noise coming from his tower. What do you suspect is the problem?
-
The RAM chips
-
The power supply
-
The hard drive
-
The operating system
Correct Answer
A. The hard driveExplanation
The symptoms described by Billy—excessive error messages, garbled file and folder names, and an odd noise coming from the tower—are typical indicators of a failing hard drive. These symptoms suggest that the hard drive may be experiencing mechanical issues or data corruption:Excessive error messages often occur when the system cannot read or write data correctly due to bad sectors or other physical defects on the hard drive.Garbled file and folder names are a sign of data corruption, which can happen when the drive's read/write heads fail or there are other physical or logical issues.Odd noises, such as clicking, grinding, or whirring, coming from the tower strongly point to mechanical failures within the hard drive.Given these specific symptoms, it is likely that the hard drive is the component at fault, and it may need to be replaced to resolve the issue. Other components like the RAM, power supply, or the operating system are less likely to cause these particular problems directly.Rate this question:

(Networking) You are having a trouble connecting to Microsoft's website and you found that the name is not being resolved to an IP address. Which tool is used to convert this name to an IP address?
-
WINS
-
DNS
-
LMHOSTS
-
PING

A user complains that her computer is suddenly running slow. She explained that she had not downloaded or installed any new software recently, and this problem had only happened one time before. Which of the following might you suspect?
-
A program trying to hog all the processes.
-
Her hard drive is corrupt.
-
She has a CMOS virus.
-
Her operating system is corrupt.
Correct Answer
A. A program trying to hog all the processes.Explanation
Sudden problems are usually caused by a program that has gone haywire and is trying to hog all the processes for itself. Hardware and software do not usually suddenly go bad. They give you notices with error messages for some time before they go bad. A CMOS virus would cause the system to crash since it affects hardware.Rate this question:

Sally complains that her computer has changed the drive letters, and she does not understand why. What should you suspect, based on what Sally has told you?
-
The hard drive is about to crash
-
The operating system is corrupt
-
She has recently added or removed a storage device.
-
Her system has a virus
Correct Answer
A. She has recently added or removed a storage device.Explanation
When a computer unexpectedly changes drive letters, it often indicates that there has been a recent change in the configuration of storage devices. This can occur when new storage devices (such as USB drives, external hard drives, or new internal storage hardware) are added or when existing ones are removed. The operating system may reassign drive letters based on the current configuration and the order in which the devices are recognized during the system's startup.This scenario is more likely than the other options because:A hard drive crash typically results in more severe symptoms, such as inability to boot or loss of data access, not just a change in drive letters.An operating system corruption usually presents more critical system errors or instability beyond just altering drive letters.While a virus can cause various unusual behaviors, changing drive letters is not a common symptom of a virus infection. It’s more likely related to hardware configuration changes.Rate this question:

Mary complains that her laptop is overheating. She checked and said that all the internal cooling systems were working properly. What do you think could help her with the situation?
-
Don't leave her laptop on for extended periods.
-
Buy a cooling pad for laptops.
-
Install a liquid cooling system.
-
Clean the inside of the computer first.
Correct Answer
A. Clean the inside of the computer first.Explanation
Even though Mary has checked and noted that the internal cooling systems are working properly, one common cause of overheating in laptops that can still persist in such cases is the accumulation of dust and debris inside the device. This can block air vents and insulate components, causing them to retain more heat than they should. Cleaning the inside of the laptop is a practical first step to ensure that air can flow freely through the cooling systems, helping to dissipate heat more effectively. It is a non-invasive and cost-effective solution compared to other more complex interventions like installing a liquid cooling system or buying new hardware like a cooling pad. This action should typically be performed periodically to maintain optimal cooling performance.Rate this question:

Which of the following could help you fix intermittent PC problems? Choose all that apply.
-
Use system restore.
-
Perform a clean boot.
-
Use checksum utility.
-
Use the undo recent changes option.
Correct Answer(s)
A. Use system restore.
A. Perform a clean boot.
A. Use the undo recent changes option.Explanation
To address intermittent PC problems, several approaches can help stabilize the system and identify the root cause:Use system restore - This feature can return the computer to a previous state where everything was functioning correctly, effectively undoing any changes that might have caused the intermittent issues. It’s a powerful tool for reversing recent system changes without affecting personal files.Perform a clean boot - By starting Windows with a minimal set of drivers and startup programs, a clean boot helps to eliminate software conflicts. This can be particularly useful in isolating a problem caused by a third-party application or service that runs at startup.Use the undo recent changes option - Similar to using system restore, this method involves manually undoing recent changes such as uninstalling recent software installations or reversing recent hardware configuration changes. It’s effective in cases where the specific change causing the issue is known.The use checksum utility option is generally used for verifying the integrity of files or disks, not directly for troubleshooting intermittent PC issues. It checks whether the current state of a file or system matches the expected state, as recorded in a checksum, and is more focused on data integrity rather than system stability or troubleshooting.Rate this question:
