As an indie game, Valheim did a great job in delivering a spooky yet palm-sweating gaming experience. But the game doesn’t run perfectly for everyone, and many players have been reporting a crashing or not launching issue. If you happen to be on the same boat, here’re some working fixes you can try.

Try these fixes:

You might not need to try them all. Simply work your way down until you hit the one that does the trick.

  1. Verify the integrity of game files
  2. Run Valheim as an administrator
  3. Update your graphics driver
  4. Install all Windows updates
  5. Check for corrupted system files 
  6. Perform a clean boot
  7. Disable in-game overlays
  8. Set valheim.exe to high priority

Fix 1: Verify the integrity of game files

One common cause of game crashes is corrupted or missing game files. You can run a scan in Steam to make sure there isn’t an integrity issue with your files.

In case you don’t know how, here’re the steps to follow:

  1. Open your Steam client and go to your LIBRARY.
  2. In the menu to your left, right-click Valheim and select Properties.
  3. Select LOCAL FILES from the left menu, then click Verify integrity of game files and wait for the checking to complete.

Once done, start Valheim and check if it crashes again.

If this fix doesn’t do the trick for you, take a look at the next one below.

Fix 2: Run Valheim as an administrator

According to some Vikings, the constant crashing could suggest a permission issue with the launcher. You can try to run Valheim as an administrator and see if it’s really the case.

Here’s a quick guide for that:

  1. Open your Steam client and go to your LIBRARY.
  2. In the left menu, right-click Valheim and move the cursor to Manage. Select Browse local files.
  3. In the pop-up window, right-click Valheim and select Run as administrator and test the gameplay.
  4. If the crash stops, you can continue to configure Valheim to always run in the administrator mode. Otherwise jump to the next solution.
  5. Right-click Valheim and select Properties.
  6. Navigate to the Compatibility tab. In the Settings section, check to box next to Run this program as an administrator. Then click OK.

Fix 3: Update your graphics driver

In most cases, the culprit to the crashing issue is a broken or outdated graphics driver. Hardware manufacturers resolve compatibility issues with new games by releasing new drivers. So you should definitely make sure your drivers are up to date before attempting anything more complicated.

You can update your graphics driver manually, by visiting the GPU manufacturer’s website, finding the latest correct installer and installing step by step. But if you don’t have the time or patience to update manually, you can do that automatically with Driver Easy.

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.
    (This requires the Pro version – you’ll be prompted to upgrade when you click Update All. If you don’t want to pay for the Pro version, you can still download and install all the drivers you need with the free version; you just have to download them one at a time, and manually install them, the normal Windows way.)
The Pro version of Driver Easy comes with full technical support. If you need assistance, please contact Driver Easy’s support team at

After updating your graphics driver, restart your PC and check if Valheim crashes again.

If the latest drivers didn’t give you luck, simply continue to the next solution.

Fix 4: Install all Windows updates

Besides drivers, it’s also important to keep your system up to date. In other words, you should make sure your PC gets all the patches and features updates. You can check for updates manually using these steps:

  1. On your keyboard, press the Windows logo key and I at the same time to open Windows Settings. Then click Update & Security.
  2. Click Check for updates. Windows will start searching for available updates. If there are any, Windows will automatically download and install the updates.
To make sure you get all the updates, repeat these steps until it prompts “You’re up to date” when you click Check for updates again.

After updating your system, do a reboot and check if there’s any improvement in Valheim.

If this method doesn’t help, you can move on to the next one.

Fix 5: Check for corrupted system files 

After couple of patches, Valheim should be stable enough for most of the players. Given we all use our computers differently, it’s likely the issue is one your end. To check if it’s a system issue, you can run a system scan with Fortect.

Fortect is a professional Windows repair tool that can scan your system’s overall status, diagnose your system configuration, identify faulty system files, and repair them automatically. It gives you entirely fresh system components with just one click, so you don’t have to reinstall Windows and all your programs.

  1. Download and install Fortect.
  2. Open Fortect. It will run a free scan of your PC and give you a detailed report of your PC status.
  3. Once finished, you’ll see a report showing all the issues. To fix all the issues automatically, click Start Repair (You’ll need to purchase the full version. It comes with a 60-day Money-Back Guarantee so you can refund anytime if Fortect doesn’t fix your problem).

Restart your computer to see if Valheim crashes again. If it does, you can try the next fix below.

Fix 6: Perform a clean boot

Feedback shows that Valheim would crash over software conflicts, which could be eliminated by uninstalling certain offending programs. So you can try to do a clean boot before locating the culprit. In doing so, Windows is started with a minimal set of drivers and startup programs.

  1. On your keyboard, press Win+R (the Windows logo key and the r key) at the same time to invoke the Run box. Type or paste msconfig and click OK.
  2. In the pop-up window, navigate to the Services tab and check the box next to Hide all Microsoft services.
  3. Uncheck all the services EXCEPT those belong to your hardware manufacturers, such as RealtekAMDNVIDIA, Logitech and Intel. Then click OK to apply the changes.
  4. On your keyboard, press CtrlShift and Esc at the same time to open Task Manager, then navigate to the Startup tab.
  5. One at a time, select any programs you suspect might be interfering, and click Disable.
  6. Restart your PC.

Now you can launch Valheim and check if the issue persists. If everything works fine, repeat the steps above but only disable half of the services and programs.

Fix 7: Disable in-game overlays

In-game overlay is a handy feature that allows you to interact with Discord and make purchases during gameplay. But in Valheim, some players found that the overlays might be hindering the game performance. So if you’re using overlays in Steam, Discord and NVIDIA GeForce Experience, try turning it off and see how things go.

Here’s an example of how to disable overlay in Steam:

  1. Open your Steam client and click Steam on the top left corner. Select Settings.
  2. Navigate to the In-Game tab, uncheck these boxes to disable the overlay feature. Click OK to save the changes.

After disabling all the overlays, you can return to Valheim and check if it crashes again.

If this trick doesn’t help you, simply try the next one.

Fix 8: Set valheim.exe to high priority

Some aficionados discovered that giving Valheim high priority could boost the performance and reduce crashes. You can give this a shot without installing third-party programs.

Here’s how:

  1. On your keyboard, press Ctrl+Shift+Esc at the same time to open Task Manager. Navigate to the Details tab.
  2. Right-click valheim.exe. In the context menu, expand Set priority and select High.

Now you can restart Valheim to see if there’s any improvement.
