Usually, it’ll be something innocuous and easy to fix, but there’s always the possibility it could be a sign of something more serious going on.
Why Is My Computer Buzzing?
It very much depends on what kind of “buzzing” sound your computer is producing. Does it sound like an electrical buzz? Does it sound more like a vibration? Are the fans spinning up faster and louder than usual? Does the buzzing sound have a physical grinding sound to it? These are all kinds of buzzing that could suggest other causes for the sound, but more importantly, different ways to fix it.
How to Fix Your Computer When It’s Buzzing
A general buzzing sound isn’t an apparent symptom of a problem. Therefore, it’s not a great way to diagnose an issue. However, here are some things to check and look for and some potential solutions to those problems. An excellent way to test for this is to turn your PC off and tilt it forwards, backward, and side to side to see if you hear a screw or something else rattling around as it falls or moves around the case. If it sounds like something’s loose in there, all you need to do is unplug your PC’s cables and open up the case. Then use a light to see if you can find the errant screw or object causing the rattling or buzzing sound. You should also check any fans you have to see if any cables or other things are obstructing them and causing them to make a noise when they spin up. Look at the metal heatsinks on the graphics card and CPU and see if they’ve collected dust. It can also be good to check the intake vents at the front of the PC to see if any dust filters are clogged. If any of them are, use a can of compressed air to clean them out. You can also use a lint-free cloth to wipe down the fan blades, but be careful, as they are pretty delicate. If the sound persists even after you’ve cleaned your PC in this way, it may be a specific fan’s bearings are failing. The only way to fix that is to replace the fan. Unfortunately, there’s not much you can do short of replacing the offending component, as most manufacturers don’t offer warranties or guarantees for coil whine.
