A user reports that their desktop computer occasionally freezes and displays a 'STOP' error followed by a blue screen, then restarts. This behavior is sporadic and does not always occur when performing the same task. Which of the following is the MOST likely cause?
- AIncorrect display driver
- BOverheating CPU
- CCorrupted operating system files
- DFailing RAM module
Show answer & explanationAnswer & explanation
Correct answer: D. Failing RAM module
Sporadic freezes and 'STOP' errors (Blue Screen of Death) are classic symptoms of failing RAM. While other issues can cause BSODs, RAM issues often manifest inconsistently.
Why the other options are wrong
- A. Incorrect display drivers typically cause graphical anomalies, screen flickering, or system freezes specifically during graphics-intensive tasks, not general sporadic BSODs.
- B. Overheating CPU would cause consistent shutdowns or freezes under load, not necessarily sporadic BSODs without specific load conditions.
- C. Corrupted OS files would likely cause more consistent boot issues or application crashes, not sporadic BSODs.
RAM Failure Symptoms
Symptoms of a failing RAM module often include sporadic system freezes, 'STOP' errors (Blue Screen of Death), unexpected reboots, and data corruption.
- Inconsistent system behavior
- Often leads to BSODs or unexpected reboots
- Can cause data corruption
