Also, over time the fan bearings will wear out. Use some compressed air to clear out any dust that mounts up on the fan blades. If none of this works, the rattle could very well be coming from the fan itself. Likely culprits here are drives that aren't stable within their bays or an incorrectly mounted motherboard. Second, while you're in there, double check that all your components are firmly attached. The rattle could be the fan clipping the wire and that's only going to lead to a short circuit. First, turn your computer off, open it up, and ensure that all of your cables are neatly tied back and far away from any fan blades. If that doesn't solve the problem, the rattle is probably being caused by a fan. A vibration inside your computer could transfer to the case and shake things you have sitting on it. If you can hear rattling from your computer, the first thing to do is remove anything that you have sitting on top of the case-an external drive, headset, figurine, or whatever.

You should then buy a new HDD or take the opportunity to upgrade to an SSD. If you hear these noises, immediately backup your data and stop using the drive. All of these are serious and can lead to data loss. If your HDD is failing, you will usually hear a grinding, clicking, or scratching noise. Alternatively, it could be damaged if dust or dirt finds its way inside. This is why you shouldn't move an HDD when it's turned on because you could jolt the needle and scratch the plate. Any damage to that plate can lead to data loss. To read data on an HDD, a needle skirts across a sensitive magnetic plate. If you're still using HDDs, it's important to know that they are mechanical. You can find out more in our guide to how SSDs work. SSDs are also less prone to failure compared to an HDD because they use flash memory, meaning there are no moving parts. Using an SSD means your computer will boot faster and you can access your files quicker. However, solid state drives (SSD) are now affordable and a much better option. Hard disk drives (HDD) were once the standard for computer storage due to their low cost to capacity ratio.
