Computers click because they have a few part within them that move. The click indicates that a small trickle of electricity is reaching these moving parts, but that some kind of flaw – often physical – is preventing it from fully booting. You can attempt to fix the error by checking the power cable, moving the computer to a separate power outlet and performing some basic troubleshooting on the hard drive and components. If these steps don’t help the computer to power on, open the computer case and remove unnecessary add-on cards and memory. This level of troubleshooting should only be attempted with the computer completely disconnected from the power, and only if you’re comfortable with adding and removing components within a PC.
