Hi fancyfootwork , 


Welcome to the Community Forums.


With the isolated noise on the PSU , it would be best if you have technical support informed for probable service for your desktop. Try giving them a call for faster resolution.

Video is down. Are you certain it is the PSU making the noise? On my Y900-34ISZ the fan on the CPU Cooler makes an annoying constant whine when fans are set to Smart-Auto in the BIOS. I couldn't stand it, so I eventually figured out how to set up the PWM Fan Profiles manually in the BIOS. Now everything runs cooler and the annoying whine is gone.


I figured out it was the CPU Fan by stopping that fan for just a second, and the whine was totally gone.
