​Computer problems:

​

​Here are a range of symptoms for common computer problems and some possible causes of these problems:

​Symptoms	​Software	​Hardware
​Computer is slow	​Malware, too many start-up items (Windows) or build-up of temporary files	​Hard drive is fragmented or starting to fail, not enough RAM or overloaded CPU
​Computer keeps restarting	​Automatic OS update problem, adware, virus, or other malware	​Graphics card, motherboard, or network card drivers
​Keyboard, mouse, printer, or other peripherals are not working properly	​Device driver issues	​Computer port issues or component issues.

​Troubleshooting:

T​roubleshooting is a term used to describe the strategies and methods that you can implement to solve computer problems.

​Basic troubleshooting:

​

Basic troubleshooting can be done by anyone without requiring specialist knowledge of computer system or administrative access to them. These simple steps can be used during basic troubleshooting:

​Problem: An application is running slowly or unresponsive

​

Cause 1: Application or computer has frozen due to errant instructions in memory.

Cause 2: Application or operating system is out of date.

​

Solution 1: Close or force quit the application, then reopen the application or restart the device. You can use Task manager (Ctrl+shift+delete)

Solution 2: Update the application or operating system.
