Many times when a desktop is making a strange buzzing noise - it is due to a fan malfunction of some sort. Other reasons include a power supply that is faulty or possibly a bad internal speaker.
I would first check the fan(s) for the computer. Start by turning the computer off all of the way. Next, unplug the cords from the unit. You'll need to isolate just the computer tower itself. Next, you'll want to get some compressed air or a vaccuum and gently clean out the areas where the system case fan vents are. If you know how to open the case for your desktop, it wouldn't be a bad idea to make a quick visual check inside of the case for things that may be caught in the fans. Some desktops open via screws on the back plane, and some open with a pull tab/lever.
If cleaning out the dust doesn't resolve the buzzing noise - then you'll need to make sure that the noise is not part of the electronics. If you are hearing an actual electrical buzz and not a speaker or fan noise, then there is likely a larger problem with the computer. In that case - I would take the computer to a certified professional for diagnosis.
Another culprit of buzzing noise may be a CD/DVD drive with a disk stuck in it. Make sure that you have ejected the drive to ensure no disk is stuck in the drive.
I hope this information helps!
