Q

You are attempting to troubleshoot a computer for a user. When you attempt to turn on the computer by pressing the power button, the computer turns on, and the fan spins normally. There is no output displayed on the screen from the PCIe x16 video card. You turn off the computer, remove the processor and the memory, and attempt to power on the computer again. During the boot-up sequence, you do not hear any POST beep codes, but the fans still spin normally. Which of the following is the MOST likely cause of his issue?

A

If your computer won’t boot, but fans spin continuously, it indicates a problem with the power supply, the motherboard, or overheating could be occurring. When the power supply to your computer fails, it won’t start or power up, but the fans spin (as described in this question). One of the reasons your computer won’t boot but the fans spin could be a bad processor or memory chip. To isolate this as a reason, you should remove the processor and memory and then attempt to boot up the computer and listen for a POST beep code. In this case, we could eliminate the motherboard, processor, and memory as the issue’s source since no POST beep codes were heard. Based on the symptoms and actions performed, it appears that the power supply is not providing enough wattage to all the components of the computer, which is why the fans are spinning (they use low wattage) while the rest of the system fails to boot.
