If your car starts making strange sounds, you usually pay attention to that, right?and#160; Well, this attention should also be paid when it comes to your computer because out of the ordinary sounds are often the sign of a potential meltdown.and#160; Any unusual buzzing, grinding or whirring can be an early sign that a moving part within your computer is about to go bad. For example, cooling fans are one of the most common failures we see and when the noise from a fan stops on its own, it often means that the fan stopped working altogether.and#160; Since heat is one of the worst enemies of your computer, letting your cooling fan stop working is about the same as driving a car with no water in the radiator.and#160; Whenever there's a clicking sound and you can't start the computer up, make sure you shut it off quickly and get professional help. Any clicking sound likely means you have a failing hard drive and the clicking can be causing more damage. Trying to restart a computer repeatedly will cause irreparable damage and can lead to extreme data loss, so be especially careful when you hear a clicking sound.and#160;
