General Tips to Keep in Mind

There are many devices, parts, cords, and connections on a computer, which means that there are many possible problems that could arise. In addition, your computer uses a variety of software, which can also cause problems. However, no matter what the problem is, you can use the following tips to help you find a solution:

  • Always check the cables: Many computer problems are related to an issue in the cables and connections. The easiest first step you can take to troubleshoot most problems is to check all related cables and connections.
  • Isolate the problem: If possible, try to isolate the problem. For example, if you can’t get the cursor to move on the screen, try to determine if the issue is with the mouse. If you have an extra mouse, you can alternate devices to see if the one plugged in is the issue, or use the arrow keys on the keyboard to help determine if the mouse is the source of the problem. When trying to isolate the problem, only make one change at a time. An error messageAn error message
  • Take notes about error messages: If your computer gives youerror messages, be sure to write down as much information as possible. If the basic troubleshooting steps don’t work, you may need the information.
  • Remember the steps you’ve taken, or write them down: Once you start troubleshooting, you will want to remember what you have done, so you don’t repeat yourself. If you can’t remember it, then write it down. If you end up asking someone for help, it will be much easier if they know exactly which steps you’ve taken.
