How to Repair A Computer. A computer is a complex collection of hardware and software, and problems can easily occur with computers. Knowing how to fix problems with your computer yourself can save you a lot of money on repairs and buying new hardware, and your computer will also perform well for many years. You can do a lot of maintenance effort through the operating system, and repairing your hardware is generally not as difficult as it seems.
Maintain the operating system
Remove viruses
How to Repair A Computer. Viruses are the main cause of most computer problems. By removing viruses and ensuring that your computer is virus-free, your computer’s health will be much more secure. If you don’t have an antivirus program, install it. Mac users should also install an antivirus program because Macs are already becoming targets for bigger viruses.

Delete any unwanted browser toolbars
Most toolbars can cause the browser to run slowly, and many toolbars are difficult to remove. If you can’t remove it after trying a lot of methods, you may need to reinstall your browser or install a new browser.
Remove unused programs
If you have a lot of unused programs, they will take up space, and also potentially slow down your computer because the programs might be running in the background. Check the list of programs and remove programs that are no longer in use. See this guide to learn how to remove programs in OS X.
Clean the computer startup process. Many programs, whether legitimate or not, will run themselves during the startup process. When too many programs are started when the operating system starts up, the computer’s performance can actually slow down.
Clean up hard drive space (hard disk)
For optimal efficiency, hard drives should always have at least 15% of the available space, preferably at least 25% of the space available. By having lots of free space, the operating system can move files in the installation and defragment process more smoothly.
Clean the registry (Windows)
The Windows Registry contains information for all installed programs. Often when programs are removed, they leave data in the registry. As the registry accumulates, Windows takes longer to find the required data in the registry.
Install updates
Most of the time, problems that are encountered frequently can be fixed by updating the operating system. By installing the latest version update, you can also ensure that your computer is safe from outside attacks.
Set up a data backup system
When something bad happens to a computer, the worst that can happen is data loss. By setting up a data backup system, you can protect your important files from hardware failure or virus attack. With data backups for all important things, a hardware replacement is also easier to do.
Reinstall the operating system
If you can’t solve a problem your operating system is having, it might be easier if you reinstall your operating system and start everything from scratch. With the data that has been backed up, the re-installation process can be done very easily
