    I was recently installing an upgrade on my PC and noticed a yellow light on the motherboard. It was a warning indicator letting me know that there was something wrong with the device. Although I was a bit apprehensive, I was determined to get to the bottom of the issue. I examined the manual and it noted that the yellow light indicated a problem with the power supply to the motherboard.

    I unplugged all the cords, inspected each of them, plugged it all back in and the yellow light remained on. I then decided to take the PC to a certified technician to take a look. After troubleshooting, the technician determined that it was in fact a power issue. He explained that the power supply did not have enough wattage to provide the necessary power to the motherboard.
