Caution: These PC noises are warning signals

We’re used to our PCs humming and buzzing, but there are some noises you shouldn’t ignore as they can indicate serious problems. A high-pitched whine can be a sign of “coil whine,” a vibration of electrical components under load.

The noise can indicate poor-quality components that may fail sooner than expected. If the whistling only occurs under high load, such as when rendering videos, it is often harmless. If the noise is constant, you should have the component in question checked or have it replaced under warranty.




You should listen carefully to certain noises coming from your PC. In the worst case scenario, this could indicate a hardware problem that you should solve in good time.

A humming fan noise is normally reassuring and a sign that your system is being cooled. However, if this noise turns into a buzzing roar, this is an indication that dust has accumulated on the fan blades or the bearings are worn.

A thorough cleaning can do a good job here. Replacing the fans can also help. However, if a fan sounds like the ticking of a clock, this could mean that the fan blades are hitting an obstacle, such as a cable. This should be rectified very quickly, as a faulty fan can cause your components to overheat and, in the worst case, can even cause a short circuit or fire if cables are damaged.

The clicking of a hard drive is particularly alarming. If you hear such a noise from your HDD, this is a clear sign that the drive is about to fail. In this case, it is advisable to back up your data immediately and replace the hard drive.

Creaking, popping, or cracking noises, especially on laptops, can be caused by thermal expansion and contraction of the internal parts. An occasional creak is normal, but loud noises, especially when moving the screen hinge, are a serious warning sign of a possible malfunction or impending failure.

Under no circumstance should you ignore a hissing or whistling noise. This may indicate serious electrical problems, which, in the worst case, could cause a fire. If you hear such noises, it is advisable to switch off the appliance immediately, disconnect it from the power source, and have it checked professionally.

All of these signals are serious warnings that your computer has problems that you should not take lightly. For this reason, a proactive approach can help you avoid major damage and data loss. The next time your computer makes unusual noises, don’t ignore them. On the contrary: If you investigate them, you can often prevent major problems.
