It can be a frustrating ordeal when your computer doesn't boot, but there are solutions.
If your computer has power but doesn't boot your operating system, a number of possibilities could be the culprit. The solution lies in narrowing down the possibilities until you know exactly why it isn't working properly.
Define the Problem
Computers may not boot for such a large number of reasons, determining the correct solution is a matter of eliminating possibilities. The first thing you need to do is be absolutely sure the motherboard does have power. If you hear your computer's case fans turn on and see display on your monitor, then your motherboard does, in fact, have power.
Macs
If you have a Mac, common things you might see include an empty, blue screen, a "broken folder" icon, a blank, gray screen or a flashing question mark. Apple offers support on its website to help diagnose possible problems and solutions.
PCs
If your computer runs a Windows operating system, there are two ways of a fixing a computer that won't boot. "System Restore" is a feature that helps restore your system to an earlier point when everything worked smoothly. "Startup Repair" is a recovery tool that can fix problems like missing or damaged system files. Microsoft offers support advice on its website to help diagnose the problem and suggest solutions.
