You’ve gotten a bad malware infection, or your Operating System is beyond repair. An Operating System reinstall often provides a stable & fresh environment which can be a welcoming change compared to a non functioning computer. During this process your personal files such as Documents and Photos will be backed up so they can be restored after the Reinstall. In some cases original restore disks will be obtained from the manufacturer; you will be informed of the costs and timeline before this is done. Any software you have installed will need to be reinstalled. In most cases this can be re-download in the case of the latest versions of Microsoft Office or Intuit QuickBooks, but it is recommended to find any software licenses and install disks beforehand.
You’ve built a computer on your own, or we have. We will install a fresh copy of Windows if you choose to buy Windows, or we will install a distribution of Linux to your liking. Part of this will be checking compatibility with hardware and installing any drivers needed. At the end free and/or open source software will be installed that was checked from a list, which can include LibreOffice, for creating and editing documents, spreadsheets, and other basic office files, and Thunderbird, an email application.
