Basic troubleshooting techniques

There are several things that could cause a problem with your computer.

As you gain more experience with troubleshooting, you'll start to learn more about what causes common problems and how to fix them. No matter what you're trying to solve, we recommend starting by using the following tips.

If you end up asking others for help, it will be much easier if they know exactly what you've tried already.
• Take notes about error messages. If your computer gives you an error message, be sure to write down as much information as possible. You may be able to use this information later to find out if other people are having the same error.
• Always check the cables. If you're having trouble with a specific piece of computer hardware, such as your monitor or keyboard, an easy first step is to check all related cables to make sure they're properly connected.
• Restart the computer. When all else fails, one of the best things to try is simply restarting the computer. This can solve a lot of basic issues you may experience.
