Troubleshooting Guide

Do you know what to do if your computer doesn't turn on?  What if your sound isn't working or your computer seems slow?  There are several basic troubleshooting techniques you can use to fix issues like these.

Please keep in mind – there are often many things that could cause a particular problem.  Troubleshooting is often a process of trial and error and you may need to use several different approaches before a solution is found.  We have a few recommendations in this process.

  • Write down any error messages.  This is extremely helpful information.  If unfamiliar with the message, you can research the error by typing the message in a web search engine, such as Google, or your computer's help feature.  You may also look for informative articles in Detroit Mercy’s Knowledge Base.
  • Write down troubleshooting steps.  This will help you to remember exactly what you have tried and, if you ask for help, it will be much easier to tell others what you have tried so far. 
  • Check the cable connections.  If you are having trouble with a specific piece of hardware, such as your keyboard or monitor, an easy first step is to make sure the device is properly connected. 
  • Restart the computer.  A lot of basic issues can be resolved simply by restarting your computer.

    The computer will not turn on

    1. Check the power cord to confirm that it is plugged securely into the computer and the power outlet.
    2. Make sure the outlet is working. You can try plugging in another electrical device, such as a lamp.
    3. If the computer is plugged into a surge protector, verify that it is turned on. You may have to reset the surge protector by turning it off and then back on. You can also plug a lamp or other device into the surge protector to verify that it's working correctly.
    4. If you are using a laptop, the battery may not be charged. Plug the AC adapter into the wall, then try to turn on the laptop. If it still doesn't startup, you may need to wait a few minutes and try again.

    Search the web

    Try searching the Web for the error message or by describing the problem that you are having.  Other users may have had similar problems and solutions to these problems are often posted online.

    You may also want to search YouTube for a video tutorial on the program that you're using.

    Keep in mind that most computer problems have simple solutions, although it may take some time to find them. For difficult problems, a more drastic solution may be required, like reformatting your hard drive or reinstalling your operating system. If you think you might need a solution like this, we recommend consulting a professional first. If you're not a computer expert, it's possible that attempting these solutions could make the situation worse.

There, you'll find instructions on how to do things, troubleshooting tips, and answers to frequently asked questions.
