How to Fix & Repair a Computer for Free

ShareThis

Repairing your computer does not always require the services of a costly computer technician. Most problems on today's operating systems can be solved by using the System Restore feature you already have at your fingertips. Be sure to back up files beforehand; some features will erase data files. Refer to your user's manual for further details.

Systems Restore
Click "Start" and type "System Restore" in the "Search" box.

Press "Enter" and select "Use a different restore point."

Choose a date prior to the time your computer first began exhibiting problems.

Press "Next" to restore your computer, fixing the problem at no cost to you.

System Repair
Insert your Windows disc into the computer and restart the PC.

Press any key when prompted to boot from the installation CD.

Choose your language, keyboard layout, and currency type from the onscreen menus.

Click "Install Now" and click "Get Important Updates."

Enter your product key number, select "Accept" when presented with the license agreement, and click the "Custom Installation" button. Highlight the drive containing your current Windows installation (this is almost always "C") and press "Next" to reinstall the operating system, restoring the computer to default conditions and alleviating problems.

Startup Repair
Insert the Windows DVD into the computer.

Restart the computer. Press any key when prompted to boot from the disc.

Enter your language, keyboard, and currency options.

Click "Repair your computer."

Select the drive containing your Windows installation (this is almost always the "C" drive) and press "Next" to repair the computer.

Tips & Warnings

Choose the System Restore option if you are experiencing minor errors with your computer that only recently began to occur, such as random reboots or error messages. Choose the reinstallation option if you are experiencing major problems with your computer such as viruses or severe malware infections. Choose the Startup Repair option if your computer is unable to boot into the operating system.
Using the System Restore or Startup Repair feature will not modify your saved user files, such as text or Word files, so do not be concerned that you will lose personal data.
Using the operating system reinstallation method will definitely delete your user files on the drive, so back up important information to removable media (USB drive, SD card, CD, or DVD) beforehand if you choose this option.
