Today, my speakers started making a buzzing noise, and I was wondering if this could be a bad thing or not.

It comes and goes, it stays for around 5-10 seconds then leaves for about an hour or so.

My speakers do continue making a buzzing sound if I turn the sound off.

Hi
This could be interference being transmitted through the speakers power supply.
The most common causes of this type of interference are fridges freezers and air conditioners and almost anything with a motor in and could be in your neighbors house.It can be a sign that the electrical filter in that appliance has failed.
The smoothing capacitors in your speaker power supply are obviously not removing this .
