Minecraft won't start - what to do? What to do if Minecraft won't start? Why won't Minecraft 1.5 2 turn on?

It’s unpleasant when Minecraft starts to behave in a bad way – it slows down, freezes, and refuses to start. You are going to play a little, but your favorite world of cubes is not going to let you in.

What to do in such a situation? There may be several reasons why the game refuses to start. Let's figure out what to do if Minecraft won't start.

Java crash

One of the most common problems is Java not working correctly. In this case, there is little point in trying to fix everything; it is much easier to take more radical measures.

• Remove all Java components. If you can’t find the corresponding line in the list of programs and components, use one of the third-party uninstallation programs - the very popular CCleaner does an excellent job of this.
• Then you need to reboot.
• Download the latest version of Java. Remember that you need the option that is suitable for your operating system. If it is 32-bit, then the corresponding version is necessary, if it is 64-bit, the same. You can find out which version you have installed by looking in the Control Panel or by pressing the simple Win+PauseBreak key combination.
• Download the game launcher.
• Before starting, get rid of the folders located at Users\AppData\Roaming\Minecraft folder.
• Now you need to launch the launcher. Enter your registration details and play.

It is recommended not to save it to the desktop - this often helps to avoid problems during startup. Sometimes Java stubbornly refuses to be removed. In this case, you should deal with it using the utility from the Microsoft operating system - Fix it. This is a simple program that finds and fixes various types of problems.

Problems with the video card

What if everything was fine with Java, but Minecraft still resolutely refuses to start? No need to worry, it’s better to read the message it gives. If it says something about the video card driver, it's time to change it. For those who do not remember which device they have installed, we recommend that you look into the manager. When you have clarified this information, go to the equipment manufacturer’s website, download the required driver from there and update your outdated software. Typically, such actions allow you to get rid of problems with different games.

The list of servers is not displayed

Sometimes the list of servers is not shown. This happens because it is blocked by an antivirus or Windows firewall. Check the hosts file located in one of the operating system folders: system32/drivers/etc. It opens with any text editor. If at the bottom you see any lines related to Minecraft, feel free to delete them.

It’s very unpleasant when you can’t do something in Minecraft. It’s even more unpleasant when the game lags. But when Minecraft doesn’t start at all, then your head is against the wall! Therefore, in order to preserve your property, this article was written. Take pity on your property - read the manual.

So, Minecraft won't start. Why? What to do? There can be several reasons why the most annoying problem occurs. Let's consider both the reasons and possible solutions.

Problems with Java

Probably the most common Minecraft problem is related to java not working correctly. Take drastic measures:

• Remove all Java components. In the Control Panel, find the corresponding item. Alternatively, you can use a third-party program, for example, CCcleaner.
• Reboot.
• Download Java. You need to download the option that suits you. If your OS is 32-bit, install java for such a system. If the axis is 64-bit, download and install the appropriate one. To find out your version, the key combination will help you - win+pausebreak.
• Download the launcher. Unpack it (preferably not “put” it on your desktop).
• Delete folders: if you have Win 7, then this one

And if you haven’t mastered 7 yet, but are using Windows XP, then this

• Launch the launcher. Then enter your registration information. And again, try not to launch it from the Desktop. From disk “C”, from “D”, but just go around the table. If this tip doesn't help, try running the launcher without unpacking it first. In some cases, this is what helps with problems with Minecraft.

What to do? Try using the utility from the ubiquitous Microsoft - "Fix it". This program allows you to find and fix problems that prevent you from installing and uninstalling applications. It should help you too.

It's all the video processor's fault.

Java seems to be sorted out. Let's assume that everything is OK with this, but Minecraft still won't start. You have already tried 7 or 70 times, but evil fate continues to interfere. Calm down, it’s quite possible that rock has nothing to do with it. If a window pops up, as in the screenshot, then the problem lies in the video card.

Well, this “lemon” can easily be turned into a delicious “lemonade”. It is enough to update the video card drivers. If you have forgotten, or even don’t know what kind of card you have, click "win+r". A window will pop up in which you write "dxdiag". Confirm your desire to be informed by pressing “Enter”. A window will pop up again, containing a lot of information about your PC. Find the “screen” or “monitor” tab (depending on your Windows, whether you have Windows 7 or others). Find out what brand the video card is, look at what model it is. Then go to the manufacturer. Each of them, be it Radeon, Geforce, Intel or others, will require you to indicate the OS type and card model. You already know the model, but look at the operating system in the same place where you found out the details about the video processor. Knowing the technical nuances, download and install the driver.

It won't hurt you to update your drivers even when Minecraft starts up just fine, but during the game some problems related to the video appear, for example, something is not displayed correctly. Moreover, the system can convince you that no updates are needed. You send the system to the farm, and follow the good advice.

Troubles with a list of servers

It happens that Minecraft does not start because the list of servers is not shown. Or it appears, but there are problems loading. Most likely, an antivirus or firewall is blocking the connection. You can fix this problem by excluding Minecraft from the list of “enemies”. Dig around here and there, and “ask” them not to pay attention to the game.

Quite often, players ask why Minecraft does not start or produces various errors. Today we will try to find out what might be happening in this case and how to fix the problems that have arisen.

Lack of Java

The first reason why you may be having a problem is the lack of a so-called Java add-on. It is needed for proper operation of applications and graphics. Of course, in this case, the computer itself will “tell” why Minecraft won’t start, giving you the corresponding error. More precisely, a message when trying to play.

If you see a message that there is no Java, then you need to install it. Download the required component (usually they simply copy it directly from the message and search for it), then install it and restart the computer. After this the problem should go away.

True, sometimes you just need to reinstall the version of Java itself. To do this, remove the previous one and install a new one “on top”. If you receive a message that it cannot be uninstalled, use the JavaMSIFix utility.

or incorrect display

Another reason why "Minecraft" may be due to a video card failure. In this situation, the player usually experiences a “black screen” instead of playing the game. But it also happens that the toy starts, only with huge glitches - textures and objects are displayed incorrectly. To the point where it becomes simply impossible to play. So the video card is another reason why Minecraft won’t start. But how to solve it?

The first option is to reinstall the driver for the video card. Download the latest available version from the manufacturer's official website, then install it on your computer and restart your computer. Try playing Minecraft. It should work.

If, after reinstalling the drivers, Minecraft does not start, which you don’t know what to do, but you have Java installed, then most likely the problem is with your computer’s video card. Try changing it. The black screen problem will go away on its own. Just don't forget to install the drivers on your PC.

Server

Sometimes players may experience a problem where the Minecraft server does not start. In fact, it becomes impossible to play. The game seems to be starting, but nothing can be done. What to do in such a situation?

There are several options for the development of events here. The first is that your antivirus or firewall for some reason begins to block the game files. In this case, it is better to disable the antivirus program and add the game to the firewall as an exception. Restart your computer and try to start again.

The second scenario is less pleasant - a virus has decided to visit you. More precisely, Minecraft's competitors decided to replace the official servers with their own. You will see this process on the monitor during the startup attempt. Because of this substitution, Minecraft will not start. What to do? It is best to completely remove the game, check your computer for viruses, cure it and reinstall the toy on your computer. Everything will have to work.

Virus attack

Most unpleasant reason The reason why Minecraft won't start is due to viruses. These are not the ones that competitors “send”. We are talking about the simplest attack aimed at destroying your operating system. Thus, over time, your program and some games may fail. What to do?

First of all, save all the important data you have. It's better to use an external hard drive - it holds quite a lot a large number of information. After this, you should check your computer for viruses. If something is detected, do not rush to immediately delete infected files. Try to cure them first. In cases where this is not possible, send them to “quarantine” and then delete them. Once the process is complete, restart your computer. If everything went well, it will be cured, and all programs and games will start working properly again.

However, here you need to be prepared for the fact that after treatment the system may refuse to start at all. Then you will need to reinstall it. In this case, after installing all drivers, games and programs will work correctly.

There are a number useful tips, which will help you solve the problem of why Minecraft won’t start. Let's see what you can do to prevent this problem from occurring to you:

1. First, make sure your computer has enough free space. It is better to have 2-3 GB of free memory. Quite often, games do not launch only due to lack of free space.
2. Download latest version JavaScript and install it. After this, be sure to restart your computer.
3. Check your drivers for updates in a timely manner. Reinstall them if necessary.

In addition, try not to use third-party programs to play Minecraft. Use only honest methods.

Why won't Minecraft launch?

A problem with starting Minecraft may occur due to a video card failure. In this case, the user will see only a black screen in front of him or, in some cases, the image will be displayed incorrectly. There are several ways to solve the problem. Option one is to reinstall the video card drivers. You should download the version from the manufacturer’s official website, this will avoid problems with viruses.

Minecraft launcher does not start on Windows 7, 8, 10

Minecraft may not start if someone tries to take over the official game servers with their pirated copies. In this case, there is nothing left but to completely remove the game elements from the computer, check the machine for viruses, if any are found, cure the infected files and then reinstall the toy.

The launch of Minecraft may be stopped due to a so-called virus attack.

If such a problem is established, then you need to try to cure the infected computer files. After successful treatment with the file, Minecraft should start.

To avoid problems with running Minecraft, it is recommended to always leave free memory on your computer and update drivers promptly.

What to do if nothing helps?

You need to do some work on your system. We suggest doing this using two useful programs.

1. Update drivers with Driver Booster. This is really cool software that often helps. Updating old drivers to new ones is one of the key requirements for the normal functioning of games and programs on a computer.

You might think that Windows always alerts users when new updates are available. That's right, it shows alerts, but only for updates for Windows and the video card. But besides this, there are many more drivers that need to be updated regularly.

2. PC repair with Reimage Repair. Run this program to analyze your system for errors (and there will be 100% of them). You will then be asked to cure them, either individually or all at once.

Result:

Minecraft or Minecraft is one of the most popular indie games today, which has tens of thousands of loyal fans around the world. Some players who are just starting to join this new gaming space encounter problems with the game. In this article we will try to figure out why the Minecraft game does not work and how it can be fixed.

Missing or outdated version of Java on your computer

The Minecraft game is written in the Java programming language and without the corresponding software Minecraft will not run on your computer.

First, you need to find out what type of operating system is installed on your computer - 32-bit or 64-bit. Based on this, download the latest version of the program from the official java.com website and install it on your device. If you already have Java installed, just connect to the Internet and automatically update your system to the latest version.

The game is saved on the desktop

For many people, Minecraft does not start because the program launcher was placed on the desktop. We recommend initially saving it to some other folder on your computer to avoid problems later.

Problems with the video card

Another popular problem why minecraft does not work is a problem with the operation of the video card. If, while loading the game, the message “Bad video card drivers!” pops up in front of you, this means that you need to update the drivers. Try downloading from the manufacturer's official website (for example, use the nVidia or Radeon websites) and run the drivers for your video card model on your computer. Updating drivers will also be useful if the game starts but is not displayed correctly.

Server problems

If you do not see a list of servers in Minecraft, the connection to the remote server may be blocked by an antivirus or firewall. Of course, the easiest way to solve this problem is to simply turn them off for the duration of the game. But we do not advise you to do this. It's better to dig into the settings and add all files and connections related to the game to the exclusion list.

Those who are looking for an answer to the question of why the Minecraft server is not working may have some problems with the host file. In order to check the correctness of this belief, first enable the display of all hidden folders on the computer, and then open the host file in Notepad, which is located at c:\windows\system32\drtivers\etc. Check to see if there are any redundant or suspicious entries. If there is something unnecessary, feel free to delete these entries, save the changes and try to connect to the Minecraft server again.

Connecting mods

If you want to make any modifications with the standard version of the game, you must download special mod files and install them correctly on your device.

Those who have a question when playing Minecraft, why mods don’t work, most likely simply install them incorrectly. Below is detailed instructions how to do it right.

To be able to easily install and manage mods, you will need to download ModLoader, Minecraft Forge (for game version 1.6 and higher), Player API, LiteLoader.

1. Find the minecraft.jar file on your device.
2. Open it using an archiver or a special program Mod Installer.
3. Next, you will need to delete the META-INF folder.
4. Download the archive with the mod you are interested in to your device. Be extremely careful, as some mods can harm your computer and contain various viruses. Therefore, download mods only from trusted sources and from developers you know.
5. Transfer the mod files to the minecraft.jar folder.
6. If you are using a version of the game before 1.5.2, then from the archive with the mod the files from the resources folder will need to be transferred to the .minecraft folder, and from the bin/jar folder they will need to be extracted to minecraft.jar.
7. Starting with game version 1.6, Minecraft Forge is used to work with mods. To install the mod, its files will need to be unzipped into the 1.6.2-Forge9.10.0.804 folder, after which all you have to do in the launcher is select the appropriate game profile.

Despite the enormous popularity of the Minecraft game, it crashes quite often. Many users complain that they cannot launch it. In most cases, rebooting the system does not help, but you should definitely consider other options.

From our article you can find out why Minecraft won’t start.

Reasons why Minecraft won't start

There are several reasons why the game won't launch; To find out what's wrong, you'll need to go through several options. However, you will be rewarded, and soon you will be able to play your favorite game to your heart's content.

Lack of Java

In most cases, Minecraft does not start due to the lack of the Java add-on. This software is necessary for correct operation of applications and graphics. If this is indeed the case, the PC will automatically display a message on the screen containing the error and a way to fix it.

When a message appears on the screen about the absence of a Java component, you need to install it. You just need to download it by copying the name from the system message. After installing it, you should restart your PC and the problem will go away. In some cases, you may need to reinstall Java, so it is better to remove it from your computer and install it again.

Video card failure

A video card failure may be the reason why the game cannot start. If this is indeed the case, then when you launch Minecraft you will see that a “black screen” appears; you may also see textures and objects that are displayed incorrectly. To solve this problem, you need to reinstall the driver for the video card. It is best to go to the official website and download the latest version of the software. After installation, restart your PC and try starting Minecraft again. If the problem is not solved, then you need to change the video card, since for some reason it has become unusable.

Virus

Minecraft may not start due to viruses, so you should check your PC for them. To do this, you can use an antivirus program that is installed on your computer. It would also be a good idea to download various utilities and check your PC with them as well. The Doctor Web utility is excellent at searching for viruses; you can download it here - freedrweb.com. You will need to run the program, and if it finds viruses, then you need to disinfect the infected files or delete them.

"Dishonest" software

It takes a lot of time to complete the Minecraft game. But there are programs that can do this much faster. This software is not provided by the developers, it is created by the players themselves, and therefore is considered a kind of scam. Often, due to such programs, the game crashes and does not want to start, so you should remember this and not cheat, otherwise you will later have to reinstall Minecraft and start all over again.

It’s very unpleasant when you can’t do something in Minecraft. It’s even more unpleasant when the game lags. But when Minecraft doesn’t start at all, then your head is against the wall! Therefore, in order to preserve your property, this article was written. Take pity on your property - read the manual.

So, Minecraft won't start. Why? What to do? There can be several reasons why the most annoying problem occurs. Let's consider both the reasons and possible solutions.

Problems with Java

Probably the most common Minecraft problem is related to java not working correctly. Take drastic measures:

• Remove all Java components. In the Control Panel, find the corresponding item. Alternatively, you can use a third-party program, for example, CCcleaner.
• Reboot.
• Download Java. You need to download the option that suits you. If your OS is 32-bit, install java for such a system. If the axis is 64-bit, download and install the appropriate one. To find out your version, the key combination will help you - win+pausebreak.
• Download the launcher. Unpack it (preferably not “put” it on your desktop).
• Delete folders: if you have Win 7, then this one

And if you haven’t mastered 7 yet, but are using Windows XP, then this

• Launch the launcher. Then enter your registration information. And again, try not to launch it from the Desktop. From disk “C”, from “D”, but just go around the table. If this tip doesn't help, try running the launcher without unpacking it first. In some cases, this is what helps with problems with Minecraft.

What to do? Try using the utility from the ubiquitous Microsoft - "Fix it". This program allows you to find and fix problems that prevent you from installing and uninstalling applications. It should help you too.

It's all the video processor's fault.

Java seems to be sorted out. Let's assume that everything is OK with this, but Minecraft still won't start. You have already tried 7 or 70 times, but evil fate continues to interfere. Calm down, it’s quite possible that rock has nothing to do with it. If a window pops up, as in the screenshot, then the problem lies in the video card.

Well, this “lemon” can easily be turned into a delicious “lemonade”. It is enough to update the video card drivers. If you have forgotten, or even don’t know what kind of card you have, click "win+r". A window will pop up in which you write "dxdiag". Confirm your desire to be informed by pressing “Enter”. A window will pop up again, containing a lot of information about your PC. Find the “screen” or “monitor” tab (depending on your Windows, whether you have Windows 7 or others). Find out what brand the video card is, look at what model it is. Then go to the manufacturer. Each of them, be it Radeon, Geforce, Intel or others, will require you to indicate the OS type and card model. You already know the model, but look at the operating system in the same place where you found out the details about the video processor. Knowing the technical nuances, download and install the driver.

It won't hurt you to update your drivers even when Minecraft starts up just fine, but during the game some problems related to the video appear, for example, something is not displayed correctly. Moreover, the system can convince you that no updates are needed. You send the system to the farm, and follow the good advice.

Troubles with a list of servers

It happens that Minecraft does not start because the list of servers is not shown. Or it appears, but there are problems loading. Most likely, an antivirus or firewall is blocking the connection. You can fix this problem by excluding Minecraft from the list of “enemies”. Dig around here and there, and “ask” them not to pay attention to the game.
