A technician is troubleshooting a desktop computer that powers on when the power button is pressed, but it fails to complete the Power-On Self-Test (POST) and continuously emits repeating single beep codes. Which sequence of steps should the technician follow to systematically isolate and resolve the memory issue?
- 1Disconnect all external peripherals and internal non-essential expansion hardware.
- 2Remove all existing RAM modules and visually inspect the memory slots for debris or pin damage.
- 3Insert a single known-good RAM module into the primary DIMM slot and test for successful POST.
- 4Reintroduce the original RAM modules one at a time to identify the specific failing module.
Cevap
The proper troubleshooting sequence requires isolating the system to core components, inspecting cleared memory slots, verifying motherboard functionality using a single known-good memory module, and systematically testing individual original RAM sticks.
According to CompTIA hardware troubleshooting methodology, isolating a memory POST issue requires minimizing system complexity first, inspecting physical slots, confirming system stability with a single known-good RAM module, and then testing suspect modules individually.
