The answer is a loose or faulty RAM module, not the newly installed graphics card. Long, continuous beeps during the Power-On Self-Test (POST) are a standardized BIOS code that specifically signals a memory failure, meaning the system cannot initialize RAM to begin the boot process. On the CompTIA A+ Core 1 220-1201 exam, this question tests your ability to interpret POST beep codes and resist the common trap of assuming a new component is always the culprit—a classic misdirection where the symptom appears right after a graphics card install. Remember that video issues typically produce a different beep pattern (often one long followed by two or three short beeps) or no beeps at all. A helpful memory tip: “Long and continuous means memory is suspicious.” Always reseat the RAM first before troubleshooting the GPU, as a bumped stick during installation is a frequent real-world cause of this exact symptom.
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 customer reports that their desktop PC emits a series of long, continuous beeps and the screen remains blank. They recently installed a new graphics card. What is the most likely cause?
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.
Why wrong: Incorrect; graphics card issues usually produce different beep patterns (e.g., one long, two short) or no beeps at all if the card is faulty.
B
The RAM module is loose or faulty.
Correct; long continuous beeps are a standard POST code for memory problems, which is the most likely cause given the symptoms.
C
The power supply unit is failing.
Why wrong: Incorrect; a failing PSU usually causes random shutdowns or no power, not a specific beep pattern.
D
The monitor is not connected to the graphics card.
Why wrong: Incorrect; a disconnected monitor would show a blank screen but no beeps, as the system would still boot normally.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The RAM module is loose or faulty.
A series of long, continuous beeps typically indicates a memory (RAM) issue, not a graphics card problem. This is a common POST code that helps isolate hardware faults before the system can boot.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Incorrect; graphics card issues usually produce different beep patterns (e.g., one long, two short) or no beeps at all if the card is faulty.
✓
The RAM module is loose or faulty.
Why this is correct
Correct; long continuous beeps are a standard POST code for memory problems, which is the most likely cause given the symptoms.

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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A customer reports that their desktop PC emits a series of three long beeps and then nothing appears on the screen. The system was working fine yesterday. What is the most likely cause of this issue?
easy
A.Faulty power supply unit
✓ B.Loose or failed RAM module
C.Overheating CPU
D.Corrupted operating system files
Why B: Three long beeps during POST typically indicate a memory (RAM) failure. This is a common POST code for many BIOS manufacturers, and reseating or replacing the RAM modules is the first troubleshooting step. The beeps are a diagnostic signal from the motherboard that the system cannot proceed without functional memory.
Variation 2. A user reports that their desktop PC emits a series of short beeps and fails to boot. The monitor shows no display, and the keyboard and mouse LEDs are off. What is the most likely cause?
easy
A.Faulty power supply unit
✓ B.Loose or faulty RAM module
C.Defective hard drive
D.Overheated CPU
Why B: A series of short beeps during POST typically indicates a memory (RAM) failure. The lack of display and peripheral response points to a hardware fault that prevents the system from completing POST, and RAM is the most common culprit.
