The answer is a failing hard drive or SSD. When a PC freezes under load with no errors, the system is likely pausing while the storage drive struggles to read or write data, such as when retrying operations on bad sectors or waiting for a failing controller to respond. This scenario directly tests your understanding of storage subsystem troubleshooting on the CompTIA A+ Core 1 220-1201 exam, where intermittent freezing without logged errors is a classic symptom of a failing drive rather than a RAM or CPU issue. A common trap is to suspect overheating or memory problems, but the absence of errors in Event Viewer and the behavior under heavy file access points squarely to storage. To remember this, think “load locks the drive” — when the workload increases, a failing drive locks up the system momentarily, while other components typically crash or log errors.
220-1201 Core PC Hardware Troubleshooting Practice Question
This 220-1201 practice question tests your understanding of core pc hardware troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user reports that their PC randomly freezes for a few seconds and then resumes. This happens most often when opening large files or running multiple applications. Event Viewer shows no critical errors. Which component is most likely causing the issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Failing hard drive or SSD
Intermittent freezing under load without errors often points to a failing storage drive. Hard drives with bad sectors or a failing controller can cause the system to pause while retrying reads or writes. SSDs can also cause stuttering if their controller is failing or if TRIM is not functioning.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Insufficient RAM
Why it's wrong here
Insufficient RAM typically causes out-of-memory errors or swapping, not brief freezes that recover on their own.
✓
Failing hard drive or SSD
Why this is correct
A failing drive can cause temporary hangs as the system waits for I/O operations to complete; checking S.M.A.R.T. data can confirm.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Overheating CPU
Why it's wrong here
CPU overheating causes throttling or shutdowns, not brief freezes that resolve without intervention.
✗
Outdated network driver
Why it's wrong here
Network driver issues typically cause network-related problems, not system-wide freezes during local file operations.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
