Like every other day you fire up your PC to get started, but instead of your standard boot-up screen, you find that your PC simply won’t boot. Or, even if you didn’t face an error during your PC’s boot-up, it’s possible that you might encounter an error when running a program.

While you can’t use a tool to fix booting errors of the first sort, there exist many tools that can work when you face some file corruption or an error pop-ups while you are running your PC. So let’s dive in and check out the best tools for the job.

1. SFC

While you can always turn to third-party apps, you should first try out the in-built methods given to you down by Windows and thus save your time and effort.

The Command prompt on Windows offers many such tools and tricks. One of those tools is the SFC scan, a command line tool designed to look for and repair any corrupted or missing files from your computer. To get started with SFC, follow the steps below:

  1. Head to the Start menu search bar, type in ‘sfc’, and select the best match.
  2. Type in ‘sfc /scannow’ and hit Enter.

As soon as you put in the above commands, the tool will be launched, and from there it will start looking up any problems with your PC. If the SFC tool finds any issues, it will fix them immediately.


If the SFC fails to do the job, your next fallback option will be DSIM, a free Windows tool that will scan your hard drive for any corruption or faults. Here’s how you can get started with the DSIM:

Once you have launched the Command prompt as an administrator, type in the following command and hit Enter:

Dism /Online /Cleanup-Image /CheckHealth

Give a few seconds for the scan to complete, and DSIM will look for and fix any errors on your PC as soon as it find them. If the tool doesn’t throw up any errors or problems at you after the scan, then you need try out yet another command. Type in the following command:

Dism /Online /Cleanup-Image /ScanHealth

If this tool reports any errors to you after it’s scan, run the following command to fix them:

Dism /Online /Cleanup-Image /RestoreHealth

When the repair is completed, restart your PC quickly, and you will be back in action in no time.
