Why doesn't desktop Mac startup?

Why won't iMac complete startup? After pushing start button on back of iMac the process stops after the Apple icon becomes visible and the startup bar reaches short of halfway point.

Hello!


Your Mac shows an Apple logo when it finds your built-in or external startup disk. As startup continues, you should see a progress bar, with or without the Apple logo. This screen might alternate with a blank screen several times. If your Mac is stuck on this screen or keeps restarting, see: If your Mac starts up to an Apple logo or progress bar - Apple Support.

It has likely had a hardware failure. Please follow the information in If your Mac doesn't start up all the way - Apple Support


Chances are after following the steps you will need to take the computer to your local Apple Authorized Service Provider, if you don't know of one in your general area please click the following link to begin finding one.
