Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

Answer analysis

Why the other options are wrong

Understanding why incorrect options are tempting is as important as knowing the correct answer.

• ✗

  Replace the power supply unit (PSU).

  A failing PSU could cause crashes, but the MEMORY_MANAGEMENT stop code specifically points to memory management issues, making RAM the more likely culprit.

• ✗

  Reinstall Windows 10.

  Reinstalling the OS is a drastic step and unlikely to resolve hardware-related memory crashes. Software issues should be ruled out after hardware isolation.

• ✗

  Disable the page file.

  Disabling the page file could worsen memory management and does not address the root cause of memory instability.

Technical deep dive

How to think about this question

The MEMORY_MANAGEMENT stop code (0x0000001A) is a strong indicator of issues within the system's RAM, even when basic diagnostics like Windows Memory Diagnostic pass. While WMD is a useful tool, it may not always detect subtle or intermittent instability in a DIMM, especially if the issue only manifests under specific load conditions or after a certain period of operation. When multiple new DIMMs are installed, and a memory-related error occurs, the most effective next step is to systematically isolate the potential faulty module. This involves removing all but one DIMM and testing the system, then repeating the process with each individual DIMM. This method helps pinpoint if one of the new modules is defective or incompatible, even if it passed initial checks, as a single unstable module can destabilize the entire memory subsystem. The fact that the issue started immediately after a RAM upgrade further reinforces that the new hardware is the most probable cause. The intermittent nature of the crash also suggests a subtle hardware fault rather than a catastrophic failure that would be immediately detected. The technician has already performed initial troubleshooting steps like reseating the RAM and updating the BIOS, which are good first steps to rule out simple connection issues or firmware incompatibilities. However, these steps do not isolate a potentially faulty individual DIMM. Replacing the PSU (A) is less likely given the specific memory-related stop code, as a PSU issue would typically manifest with more general system instability or power-related errors. Reinstalling Windows 10 (C) is a software solution for a problem that is almost certainly hardware-related, and disabling the page file (D) would likely exacerbate memory management issues rather than resolve them, as the page file is crucial for handling memory overflows and managing virtual memory.
