Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Test or replace the CPU
Option C is correct because if the system powers on but no POST, a faulty CPU is a common cause when other components are reseated. Option A is wrong because power supply issues would typically cause no power or cycling. Option B is wrong because the CMOS battery is for clock/BIOS settings, not boot failure. Option D is wrong because BIOS corruption is less likely after reseating.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace the CMOS battery
Why it's wrong here
A dead CMOS battery affects BIOS settings and time, but does not prevent the system from POSTing and booting.
- ✓
Test or replace the CPU
Why this is correct
A faulty CPU can cause the system to power on with fans but no POST or beep codes. This is a logical next step after verifying RAM and GPU.
- ✗
Flash the BIOS firmware
Why it's wrong here
BIOS corruption is rare and typically shows symptoms like boot loops or incorrect hardware detection; it is not the primary suspect after reseating components.
- ✗
Replace the power supply
Why it's wrong here
A failing power supply typically causes random shutdowns or failure to power on, not a complete lack of POST with fans spinning.
