Do you know what to do if your screen goes blank? What if you can't seem to close an application, or can't hear any sound from your speakers? Whenever you have a problem with your computer, don't panic! There are many basic troubleshooting techniques you can use to fix issues like this. In this lesson, we'll show you some simple things to try when troubleshooting, as well as how to solve common problems you may encounter. There are many different things that could cause a problem with your computer.
No matter what's causing the issue, troubleshooting will always be a process of trial and error —in some cases, you may need to use several different approaches before you can find a solution; other problems may be easy to fix.
We recommend starting by using the following tips. If you're having an issue with your computer, you may be able to find out what's wrong using the process of elimination.
This means you'll make a list of things that could be causing the problem and then test them out one by one to eliminate them. Although sitting requires less muscular effort than standing, it still causes physical fatigue tiredness and you need to hold parts of your body steady for long periods of time.
This reduces circulation of blood to your muscles, bones, tendons and ligaments, sometimes leading to stiffness and pain. If a workstation is not set up properly, these steady positions can put even greater stress on your muscles and joints. Preventing computer-related muscle and joint injuries Tips to avoid muscle and joint problems include: Sit at an adjustable desk specially designed for use with computers. Have the computer monitor screen either at eye level or slightly lower.
Have your keyboard at a height that lets your elbows rest comfortably at your sides. Your forearms should be roughly parallel with the floor and level with the keyboard. Adjust your chair so that your feet rest flat on the floor, or use a footstool. Use an ergonomic chair, specially designed to help your spine hold its natural curve while sitting.
Use an ergonomic keyboard so that your hands and wrists are in a more natural position. Take frequent short breaks and go for a walk, or do stretching exercises at your desk. Stand often. Computer-related overuse injuries of the hand or arm Muscles and tendons can become painful with repetitive movements and awkward postures. Symptoms of these overuse injuries include pain, swelling, stiffness of the joints, weakness and numbness.
Preventing computer-related overuse injuries Tips to avoid overuse injuries of the hand or arm include: Have your mouse at the same height as your correctly positioned keyboard. Position the mouse as close as possible to the side of the keyboard. Use your whole arm, not just your wrist, when using the mouse. Type lightly and gently.
Mix your tasks to avoid long, uninterrupted stretches of using the computer. Remove your hands from the keyboard when not actively typing, to let your arms relax. Eyestrain from computer use Focusing your eyes at the same distance point for long periods of time causes fatigue.

Focus on your operating system first. Make sure you apply any updates that are pending. The update feature should be fairly prominent in any app, but consult the built-in help options if you get stuck.
After applying all the updates you can find, your issues might be fixed. If they are, maintain this process as a way to prevent future problems in addition to fixing existing ones.
Make sure as many of your installed applications are updating themselves automatically in the background, and you should run into fewer computer issues as a result. You might think that leaving older, unused programs on your hard drive is pretty harmless, but as more and more applications mount up, your operating system has to work harder and the files on your computer get broken up more often and spread out further as your computer tries to save them—something known as fragmentation.
As a result, the amount of free storage space can quickly become limited.
