1. Update graphics card drivers

Minecraft fatal error can occur if the game is unable to use your dedicated graphics card or if the old video card drivers are creating conflict with your version of the game.

The simple solution here is to update the graphics card from the Device Manager (in case of Intel HD graphics). To do that, follow these steps:

  1. Type Device Manager in the search bar and open it.
  2. From the Device Manager, go to Display Adapter > Intel UHD Graphics.
  3. Right-click on Intel UHD Graphics and Update driver.
    Update Intel UHD Graphic Display Adapter Driver fatal error
  4. Select Search Automatically for updated driver software.

  5. If an update is found, download and install the driver.
  6. Restart your PC and check for any improvements.

Alternatively, you can update all your drivers automatically using tools such as TweakBit Driver Updater.

2. Disable antivirus and firewall

If you are facing Minecraft fatal error while updating the game to the newest release, your antivirus might be at fault. Antivirus and firewall usually block any suspicious connection to and from the PC. However, at times even genuine connections might get blocked for various reasons.

The simple solution here is to disable your antivirus temporarily along with the firewall. Alternatively, you can also add some programs to whitelist in your antivirus. If your antivirus is the problem, perhaps this is a good time to consider switching to a different antivirus.

Bitdefender offers great protection, and thanks to its Gaming Mode feature, it won’t interfere with any of your games.

Turn Off Firewall

  1. To disable Firewall, type Firewall in the search bar.
  2. Open Windows Defender Firewall. From the left pane, select Turn Windows Defender Firewall On/Off.

3. Update Minecraft

Developers frequently release new updates to keep their game bug free and to add new features. If you are running an older version of Minecraft, try to update the game to the latest version to see if any new fixes are available.

Minecraft constantly checks for new updates and automatically notifies the user if an update is available. However, in case you don’t have any notifications, check for new updates manually.

  1. Open Minecraft launcher.
  2. Click the arrow to the right of the play button and select Latest Release.
  3. If prompted, download and install the update.

4. Check for Java updates

Minecraft being a Java-based game requires you to install Java on your computer. At times, some technical bugs related to the game can be fixed by updating Java on your computer. Apart from fixing technical glitches, Java updates also bring performance improvements.

You can download the latest version of Java Build 12 and Build 13  from the given links.

Some users have reported the problem to have occurred after installing the latest version of Java. In such cases, downgrade to the older version where the game was working without the fatal error.

5. Upgrade your RAM

The modern laptops and PCs come with decent hardware that is fully capable of running Minecraft on medium settings. Minecraft is not very hardware demanding game and most of the people should be able to run it on integrated graphics.

However, if you have an old PC, the lack of hardware resources may cause a fatal error in Minecraft leading to a system crash. By lack of hardware resources, we mean RAM. To check the RAM usage, use the Task Manager and check the Performance stats.

If the RAM usage is at 100% all the time, you probably need to buy more RAM to fix the issue.

  • Don’t rely on Windows for graphics driver updates. Download drivers manually from Intel’s website.
  • Download OpenGL manually as Microsoft uses DirectX instead.
  • Reduce memory amount in Java to 512 MB.
