Why is my desktop computer not turning on?

There are hundreds of different reasons a computer may not work. Before trying to fix a non-working computer, you must first identify what part of the computer is causing it not to work. Below are the steps to help fix your computer with links to related pages that help fix a specific type of computer problem.

Is the computer getting power?

When looking at the computer do you see any lights? Are the fans moving and blowing air from the computer? If there are no lights, moving fans, or it appears the computer is not turning on, it has a power related problem. See the steps below for all power-related troubleshooting steps.

Power cord is not connected properly

It may seem obvious, but verify the power cord is connected to the back of the computer and plugged into a power outlet. If it appears to be connected correctly, disconnect and reconnect both ends of the power cord to ensure the cable is not loose.

Power strip or outlet

If you have a power strip (surge protector) or UPS (uninterruptible power supply), disconnect the computer power cord from it and connect the cord directly to the wall outlet.

If connecting the computer directly to the wall outlet still does not work, verify the outlet works by connecting another electrical device.

Power supply switch

Some computer power supplies, have a power switch on the back. Check the back of the computer and make sure there are no additional buttons that are turned off.

Tip: A power supply switch often has a "0" and "1" which is binary for "off" (0) and "on" (1).

Try holding power button for at least 10 seconds

The last step before you will have to call us. Try holding the power button for at least 10 seconds to do a hard reset. After that press the power button normally and see if that solved your problem.
