How can I fix Steam not opening or launching?

If you are unsure how to use this command, then follow these steps:

  1. Open the Run dialog box. You can do this by pressing the Windows key together. Alternatively, you can type in Run in Cortana on the Windows menu.
  2. Once the dialog is open, type in or copy this command steam://flushconfigfix steam
  3. Next, press enter and this dialog will appear from Steam.
  4. Press OK.

2. Enter Safe Mode

Configuring your PC’s settings to start in Safe Mode is another method you can use to troubleshoot this issue.

Safe Mode only allows vital applications to operate. So, if there are third-party programs interfering with the starting of the steam application, then Safe Mode should fix the problem.

Is Safe Mode is not working, this troubleshooting guide will help you fix the problem.

If your Steam application works in Safe Mode, then you need to look for the program that is disrupting Steam and disable it.

If you are not sure how to turn your Windows 10 computer into Safe Mode then follow these instructions:

  1. Type in System configuration into your search (Windows menu). Click on System configuration when it shows up.
  2. When the dialog opens go to the boot tab.
  3. There will be a Safe boot option located on the bottom left side of the dialog.
  4. Select Safe Boot and underneath it select Network. We will need the network to be running because the Steam client uses the internet. If you are still confused, you can look at the picture below for reference.
  5. The Safe Boot will take effect after you restart your computer.

3. Reinstall  Steam
