Overheating, due to dust that collects around fans and components, is considered one of the most common causes of computer failure . To maintain the proper functioning of the computer's cooling system, the inside of the computer should be cleaned every three months. Also, the amount of free space on your system's hard drive and the presence of malicious software (e.g. spyware) has a dramatic effect on the performance of your computer. In this article you will see instructions for properly maintaining a computer to ensure optimal performance.

Maintaining the operating system:
Install an antivirus and set it to run automatically. Windows computers often come with software when you buy them. If not, you can get one online for little or no cost.

Use Windows CleanUp to delete unnecessary files. The amount of free space remaining on your hard drive can have a dramatic effect on computer performance. Windows CleanUp automatically scans your computer's hard drive to identify and remove temporary files and other files that are no longer being used. Removing these unnecessary files increases the available free space, which improves system performance.
Download the latest updates for drivers to maintain optimal performance levels. You can find these updates on the manufacturer's website, usually at no charge.
