How to Fix Common Minecraft Errors in Windows 10/11

Minecraft is a great and addictive game that is highly appreciated by worldwide users, whether we are talking about portable and touch-based handsets or even desktop devices. Unfortunately, many users reported Minecraft errors under Windows 10, especially of Nvidia graphic cards and especially after updating the Windows OS.

As you can already tell, we are facing some graphic card incompatibility as the Nvidia drivers can’t properly communicate with the Windows system.

But, don’t worry as you can still play Minecraft on your Windows-based device as we are here to help you out. Of course, this is not the only Nvidia graphic card incompatibility reported by Windows 10 users as some customers also complained about some HDMI issues.

Anyway, if you want to fix the Minecraft problems and get back on track, then don’t hesitate and apply the guidelines below. This troubleshooting solution can be applied within a few minutes and can be easily completed even by a newbie so you have nothing to worry about.

How do I fix Minecraft errors in Windows 10?

1. Update Minecraft

1. First of all, on your device install the Java package. Minecraft Java edition requires at least Java version 8. You should make sure you don’t have multiple Java versions installed on Windows 10 – download Java from here. Select the Online Installation option so that you will automatically load the correct version for your system.
2. Get the Minecraft launcher. Open Minecraft and log in with your personal account.
3. Then apply the latest updates, if there are such.
4. Now, if the “bad video card drivers” alert is being displayed, just go to your Start Screen and follow the rest of the steps below.
5. Press “Wind + X” dedicated keyboard keys and run Device Manager.
6. From there head towards “Graphics Drivers” and uninstall your display drivers.
7. Then go to your manufactures official website (for example Acer, HP, Dell, and so on) – not on the Nvidia/AMD web page.
8. Download from there the drivers indicated by your manufacturer and in the end, install these drivers even in Compatibility mode for Windows 7. 
9. In the end, run Minecraft one more as you are done.

Regardless of the issue you’re currently facing, the very first thing you should have in mind when dealing with that particular problem is keeping your game updated. Because installing the latest possible version of Minecraft may solve a lot of problems.

For downloading all the outdated drivers on your PC, we suggest you use a professional driver updater tool that safely install and upgrade all the drivers you need in seconds. A dedicated tool will keep you away from any risk of malfunctions.

Good job! Now you know how to update and make Minecraft work on Windows 10.

2. Can’t load a mod in Minecraft

If you like to experiment with Minecraft mods, but can’t install your favorite mod, just change the approach.

You’ve probably been installing mods the old-fashioned way (putting files into Minecraft by yourself), which is prone to errors and issues. Instead, you should use a handy little program called Forge.

Forge basically doesn’t all the work for you. You just need to put the mod you want to install into Forge, and it will automatically implement it in the game. Saving you a lot of time and effort. You can download Forge for free from this link.

In case you need additional explaining, just watch the tutorial on how to use Forge to install Minecraft mods below:

3. Can’t play the game on LAN

1. Go to Search, type firewall, and open Windows Defender Firewall
2. Click Allow an app or feature through Windows Defender Firewall from the left pane
3. Select Minecraft/Minecraft for Windows 10 and make sure both Private and Public are checked
4. Restart your computer

If you’re still unable to play the game through LAN, make sure everything’s alright with your internet connection. In case you find out that something’s wrong, check out this article to solve the internet connection issues in Windows 10.

4. Minecraft is lagging

If you notice that your in-game performance is not great, and the game could run smoother, take these into account:

4.1 Meet the system requirements

If your computer doesn’t meet the minimum system requirements, you’re lucky to even launch the game. So, if you don’t have a computer powerful enough to play Minecraft, consider upgrading your hardware.

Minecraft system requirements:

• CPU: Intel Pentium D or AMD Athlon 64 (K8) 2.6 GHz.
• RAM: 2GB.
• GPU (Integrated): Intel HD Graphics or AMD (formerly ATI) Radeon HD Graphics with OpenGL 2.1.
• GPU (Discrete): Nvidia GeForce 9600 GT or AMD Radeon HD 2400 with OpenGL 3.1.
• HDD: At least 200MB for Game Core and Other Files.
• Java 6 Release 45.

4.2 Allocate more RAM to Minecraft

Minecraft launcher now allows you to allocate more RAM memory to the game, if you’re not satisfied with the performance. Here’s how to do that:

1. Open Minecraft Launcher
2. Go to Launch options, select your profile, and activate Advanced settings
3. Activate “JVM Arguments” and add the following command: -Xmx2048M -Xms2048M
4. Save these settings, and you’ll always start the game with 2GB of RAM. If you want to allocate more ram, simply replace 2048M with the amount of RAM you want to allocte.

4.3 Update Java

As Minecraft is powered by Java, you’ll need its latest version to run the game smoothly. You can download the latest version of Java from here.
