In some cases, formatting your PC may be the last opportunity to removing viruses that can not be eradicated with existing antivirus programs. After reformatting, you can reinstall the operating system and have a new computer.
If your computer has Windows 7, you do not need to be a computer expert to perform this task. Just follow the steps below and wait until the installation process is complete.
Notice: Before formatting your PC, we recommend that you perform a backup of your data, since it will erase all information from the hard disk and you will not be able to recover it. You can make a backup by recording your information on a DVD, a USB or an external hard drive.
How To Reformat and Clean Install Windows 7 in your PC
Restart your PC and press the corresponding keys (F5, F8, F10, F11, F12, Del) to access the BIOS. This will depend on the motherboard model, but this information appears on the first screen when you turn on your PC. In the BIOS choose the STANDARD CMOS SETUP option, look for First Boot Device and select CD / DVD so that your PC boots from the Windows 7 DVD. Then, press the ESC key to exit the menu and F10 to exit and save the changes made in the BIOS. Confirm by selecting Yes and the computer will restart. This operation allows you to first load the installation DVD instead of the operating system installed on the hard drive when your computer restarts.
Insert the Windows 7 DVD into the DVD player and wait for it to read. The following message appears on the screen: "Press any key to boot from the CD or DVD". Press any key once and wait. After this, you will see on the screen the presentation of Windows 7 where you will have to select the language, the format of time and currency, and the language of the keyboard. Select English for the system and keyboard language. The time and currency format must be configured according to your country of residence. Then click Next and click the Install Now button. Accept the license agreement by checking the respective box and clicking Next. On the next screen, select Custom (advanced) which is the custom option to perform a clean installation of the operating system. You will see the partitions you have available from your previous operating system. Select Drive C and click Format. Do the same with the other partitions if you have them.
After formatting your entire hard drive, go to Drive C where you will install Windows 7 and click Next. In the next screen you will see that Windows 7 is being installed and you will only have to wait until the process is finished. After you have finished copying the files, installing the features and upgrades, you will be prompted for a name for the primary user and a name for the system. Then, you must write a password, enter it again and indicate a clue to help you remember it. You also have the option to leave these spaces blank if you do not want to use a password to access the operating system. In the next window, enter your Windows 7 serial number. After entering the serial number, click Next and select the recommended settings. Set the time and time zone depending on your geographic location. Finally, select a type of network (work or public home). Done, the system finished configuring, after a brief wait will see the Desktop showing you the Windows 7 welcome screen.
