A technician is troubleshooting a corporate desktop computer that fails to complete the Power-On Self-Test (POST). When the power button is pressed, the system power LED turns on and cooling fans spin at full speed, but the monitor remains dark and the motherboard emits a continuous series of short beeps. Which of the following initial actions should the technician perform to isolate the issue? (Select TWO.)
- Reseat the existing system memory modules into their respective motherboard slots.Answer
- BReinstall the operating system graphics driver using recovery software.
- Test the system boot using a single known-good RAM module inserted into one slot at a time.Answer
- DReplace the installed memory sticks with standard SO-DIMM modules.
Answer
The technician should reseat the existing memory modules into their motherboard slots and test the system using a single known-good RAM module inserted into one slot at a time.
A continuous beep pattern prior to video initialization signifies a POST memory detection failure. Correct troubleshooting requires physically checking memory module contact by reseating them and testing with a single known-good memory module to isolate defective hardware components.
