A desktop workstation fails to display video upon powering on. The system power fans spin continuously, but the motherboard speaker emits three long, repeating beep codes. Which TWO of the following initial troubleshooting steps should the technician perform to isolate the cause of this failure? (Select TWO.)
- Reseat the installed RAM modules to ensure proper electrical contact in the motherboard DIMM slots.Cevap
- Boot the system using a single known-good memory module installed in the primary DIMM slot.Cevap
- CAttempt to boot into the operating system using an external recovery drive to repair system boot files.
- DReplace the desktop memory modules with SO-DIMM modules to fit standard desktop DIMM slots.
Cevap
The technician should reseat the installed RAM modules to ensure proper physical contact and attempt to boot the PC using a single known-good memory module in the primary slot to isolate memory stick or motherboard slot failure.
Three repeating long POST beep codes indicate a memory initialization failure. Reseating memory modules ensures proper connection with slot pins, while booting with a single known-good RAM module in the primary slot isolates whether a particular RAM module or slot is faulty.
