How to Repair StarCraft 2 Crash on Windows 10

Since its release in 2010, StarCraft 2 has been played by millions of people and thousands of sports professionals around the world. StarCraft 2 has something unique to it: a blockbuster genre with three races, four modes, and endless gameplay options that gives you the ultimate real-time strategy experience. However, many players report that crashes in Starcraft 2 sometimes make their game unplayable.

What causes StarCraft 2 to crash on Windows 10

After studying user reports and analyzing the game on our own computers, we came to the conclusion that crashes occur for several different reasons. The reasons for crashes are as follows.

System requirements: If StarCraft system requirements are not met, crashes will occur regardless.

Background Applications: There may be background applications that conflict with the game or compete for resources. In this case, the game will crash or hang randomly.

NVIDIA sound drivers: NVIDIA drivers (especially sound drivers) have been known to cause various problems with each update. Reinstalling or disabling these drivers may help.

The game installed on an external hard drive: Even though external hard drives have a very fast read/write ratio, they still tend to cause problems, especially when the game is running. This is probably due to the large amount of data being exchanged between the RAM and the external hard drive.

Outdated game: The Blizzard app automatically tries to install all the latest updates for your game without your involvement. However, we have seen cases where this has not worked and users have experienced a crash due to an outdated version of the game.

Damaged or outdated graphics drivers: graphics drivers are the main components that transfer information between your video card and your operating system. If your graphics drivers are somehow corrupt or outdated, you will encounter many problems, including crashes.

A variable configuration file is missing: StarCraft documents have a “variables.txt” file from which all saved configurations and settings are loaded at startup. If the file is missing or corrupt, the game freezes and crashes.

Damaged game settings: Like any game, StarCraft allows you to set in-game settings. If these settings are not set correctly or if there is a system conflict, problems such as crashes can occur.

Damaged game files: This cause cannot be ignored: if the game files themselves are damaged in any way, the game will behave strangely and cause various problems.

Before continuing, make sure you are logged in as an administrator and have an active Internet connection. Also, save your progress to the cloud, as we will be manipulating the game a lot.

Here’s how to fix StarCraft 2 crashing on Windows 10

Here's how to fix StarCraft 2 crashing on Windows 10

Update your video card drivers

If you don’t have the right driver, especially for your video card, you will always have problems when you try to play the game on your PC. This is a very important fix that can’t be stressed enough. You should always make sure that all your drivers are up to date.

If your drivers are missing, corrupt, invalid, or out of date, StarCraft will crash, run slowly or not start at all within seconds of starting.

Update your drivers via the Device Manager

  1. Open the WinX/Power User menu by right-clicking on the Start button or by pressing the Windows + X logo on your keyboard.
  2. Click Device Manager in the list.
  3. Click the arrow next to Display Adapters or double-click the option itself to expand it.
  4. Right-click on the graphics device and select Update Driver.
  5. Select the option to automatically check for the latest drivers on the Internet and on your computer.
  6. Make sure that your Internet connection is turned on.
  7. Wait for the download and installation to complete, then restart your computer.

Download the video driver from the manufacturer’s website.

This is another method you can use to update your drivers. For example, if you are using HP, you can go to their website and download the latest driver software version for your graphics device. The support assistant can even find out the specifications of your product to make sure you’re downloading the correct drivers. If you use Nvidia or Radeon, visit their website to download and install the latest software.

Keep in mind, however, that you may need to know the exact specifications of your device when you visit the manufacturer’s website to make sure you’ve downloaded the correct driver. Incompatible drivers can cause malfunctions.

Install the latest game patches

StarCraft developers regularly release patches to improve gameplay and fix various bugs. Installing patches can help solve crashes and other bugs. So check if there are updates for the game and install them. Also, remember to check for updates in the Game Launcher (i.e. the Blizzard desktop app).

Disable Overclocking

Overclocking device drivers to improve performance can cause problems in some games, including StarCraft II. If you’ve used an overclocking tool, you can override the settings in it. You can also access your system’s BIOS and CMOS and reset the default settings. To do this, refer to the user manual of your particular device.

Run the analysis and repair program

It is possible that your game files are corrupt and this is the cause of this problem. You can easily fix this problem with the Blizzard Scan and Repair tool in the desktop application. It will detect problems in StarCraft and fix them automatically.

  2. Click on StarCraft II in the left pane to select it, then click “Settings.
  3. On the menu that pops up, click “Scan and Restore.
  4. Click “Start Scan.” Once the scan has started, you may see a progress bar at the bottom of the screen to see when it is complete.
  5. After that, restart your computer and try running the game again. Check to see if the problems have been fixed.

Start the game as an administrator

StarCraft 2 problems, such as lags in the game menu, can be solved by giving the game administrator privileges.

  1. On your computer, go to the directory where the game is installed and right-click on the .exe file (it should be SC2.exe).
  2. In the window that appears, click on Properties and go to the Compatibility tab.
  3. Check the option “Run this program as an administrator”, then click on Apply and Ok to save your changes.
  4. You can now check to see if the game is working well.

Reinstalling StarCraft 2

Reinstalling the game from scratch can help if problems persist after all other solutions, especially if you used the recovery tool. You should keep your Blizzard credentials handy, as you may need them to provide the game’s download code.

Perform the following steps:

  • Open the Run dialog box by typing `Run’ in the Start menu search bar or by holding down the Windows key and pressing R.
  • Type `appwiz.cpl` in the box and press `OK` or Enter. This will take you directly to the “Uninstall or change programs” section in the Control Panel, under “Programs and Features”.
  • Find StarCraft 2 in the list and click on it. Then click “Delete/Change. You can also right-click on StarCraft 2 and then select “Uninstall” from the context menu.
