Troubleshooting Techniques: Troubleshooting a Computer
What troubleshooting techniques should you use when troubleshooting computers? Some of them are similar to troubleshooting other hardware, but the software layer in a computer adds complexity.
First, always reboot. Software left running can get glitchy.
Next consider what software may have been added to the mix. New software sometimes breaks things.
The hardware can be to blame, too, though. Power supplies can weaken over time and spinning hard drives do eventually fail.
