CompTIA A+ Core 1 (220-1201)Hardware and Network TroubleshootingMedium
A technician is troubleshooting a desktop computer that experiences random reboots and occasionally displays a 'blue screen of death' (BSOD). The user reports that these issues started after they installed new high-performance RAM modules. The technician has already verified the RAM is seated correctly. What should the technician check NEXT?
- AReplace the power supply unit (PSU).
- BUpdate the graphics card drivers.
- CCheck the hard drive's S.M.A.R.T. status.
- DRun a memory diagnostic tool.
Show answer & explanationAnswer & explanation
Correct answer: D. Run a memory diagnostic tool.
Given that the issues (random reboots, BSODs) started after installing new RAM, and the RAM is confirmed to be seated correctly, the next logical step is to test the RAM itself for faults. A memory diagnostic tool (like MemTest86) can identify issues with the RAM modules.
Why the other options are wrong
- A. While a failing PSU can cause these symptoms, the direct correlation with new RAM installation points to the RAM as the more immediate suspect, and RAM diagnostics are a less invasive first step.
- B. Graphics card drivers are unlikely to cause random reboots and BSODs specifically after new RAM installation.
- C. While a failing hard drive can cause BSODs, the timing (after RAM installation) makes it less likely to be the primary cause than the new RAM.
RAM Diagnostic Tools
Software utilities designed to test the integrity and functionality of a computer's Random Access Memory (RAM) modules.
- Identifies errors in memory that can cause system instability, crashes, and BSODs.
- Examples include MemTest86 for bootable diagnostics and Windows Memory Diagnostic.
- Essential for troubleshooting issues that arise after RAM installation or upgrade.
Memory trick: If 'new RAM' causes crashes, 'test' its health before more dashes.
