[Guide] How to fix most crashes in minecraft

Starcraft1535 · Oct 1, 2011

I didn't create this guide. I took it from the minecraft forums to help anyone have problems with the game.

FIX ONE

Lower Render Distance
Set your render distance one lower than it is already, this fixed all my crashes, it does not matter how good your machine is, mine can run Crysis 2 and completly maxed out settings (even with an "extreme" setting) with no lag, but this fixed my minecraft crashing. I was on Far and am now on normal.

FIX TWO

Do a clean install. (Windows)
First back up your saves.
MAKE SURE YOU CAN VEIW HIDDEN FILES (http://tinyurl.com/65dod2l)
C:\Users\<YOUR USER>\appdata\roaming\.minecraft
Copy the Saves folder to your desktop.
You may also want to back up texture packs.
Now delete everything else in the .minecraft folder.
Launch Minecraft and let it download all the files.
Now put your Saves folder back in your .minecraft folder.
You have just done a clean install and kept your saves.

If you are still having problems after this try:
Open the Minecraft client
Click on options (directly above Login)
Click on "Force Update!"
Click on "Done"
Log in to the game, and the client will re-download the game files

OTHERS

Make sure all your drivers are up to date, for keyboards and USB to GFX cards and Sound cards.

Update Java
Turn Smooth Lighting off
If you are running 64 Bit windows make sure you have 64 bit java.
To get 64 bit java open internet explorer 64bit
Go to java.com and download java from there.
If you are already on 64 bit java on a 64 bit device, try downgrading due to the fact that Minecraft is a 32 bit application / program. (Thanks, Sir Zirra (http://bit.ly/i1nApd)

Quote From Deadly Bagel

Right click the MineCraft folder and click Properties, then open the Security tab (if it's not there, you may have to disable simple file sharing. I think that's on the Advanced tab, but you might have to Google it)

If Users or All Users is not already in the list, add them. You may have to click 'Edit'.

Give them Full Control of the folder. Okay out of that and close the folder.

Open My Computer, C: drive, Program Files (the x86 version if it is there) and find the Java folder. Right click, click Properties, and follow the same steps above to add full control for all users.

Voila! My game was consistently crashing about 15 mins into every single session before. Been playing for hours now, not a single flicker.

Minecraft Black-Screen-Of-Death / Freeze on windows

(It seems impossible that no one has posted this solution, I tried search and couldn't find it anywhere so...)

I was getting the black screen/crash after playing for several minuets every time and tried most of the solution to no avail. I used this fix and it hasn't crashed since:

In the same directory as minecraft.exe, create a plain text file called minecraft.bat with the single line

java -Xmx1024M-Xms1024M-jar minecraft.exe

(either create a new shortcut, or change the "target" in the old shortcut from minecraft.exe to minecraft.bat)
Thats it; MAGIC!

tech info
P4 3GHz
2 GB RAM
NVIDA 8200AGP
2048MB pagefile
Minecraft Beta 1.3_01
(fullscreen, Graphics: fancy, Render Distance:normal, Limit Framerate: off, Smooth Lighting: on)

Quote from Boelens

You could add this: If you got any mods installed, and get a black screen upon startup or get stuck at loading, delete META-INF in your .minecraft folder.

It stopped the random crashings for me :3

Quote from Ekirhs (A.K.A Dave)

I had been seeing increasingly common hangs/crashes as well - got down to a minute or so of play at a time.

Things that seemed to help:
- Uninstall all old JRE/JDKs and their updates and install latest Java environment (had an old JDK that was causing problems). In my case I installed the JDK (Development environment) but if you don't need dev stuff, install just the JRE (Runtime Environment).
- Set up a .bat file to allow a path variable specific to the game that ruled out the various software dev stuff I have on my system. Also allows changes to the java command line options for stack size and stuff.
- And finally, set my pagefile to by managed by the system. This appears to have solved the quick death problem as my worlds memory footprint increased. I had a custom setting that didn't appear to be expanding past the starting size (Windows XP Pro 32bit). Don't remember why I set that up...

Anyway, good luck and I'm off to look for wolves. No sleep tonight.

Quote From hulk0g3s

Alright ladies and gents, I have been having a bit of a crash issue with the 64 bit version set up.
I loaded up MC, clicked yes to the new 1.5 update and riiiight after that boom error so quick I could not read it and the app closed/crashed.
Deleting the bin did not fix it. Java has been updated with the proper 64bit option. You cannot get into any settings since the game crashes before you can see the world selection screen.

What I did to fix this was use minecraft patcher 2.0.0 beta 3 .
I cannot remember where I got it, but my man Rico hooked me up with this. Once you have it and launch it you have 2 options. 1 is to patch > this worked for me. On the other hand you have option 2 unpatch. This I have not messed with, but I am sure if a an update goes badly you could use this and play like you did before until a fix would be released. Works for HD and 64bit systems.

I'm now off to my achievement hunting......hope this helps many!!!

Flame on.... ...oh shizz my house is on fire. I gotta go.

Quote From TonViper @ Crashes when loading world.

Does this happen on a specific world, or with all your worlds? If it is only one specific world, that world may be corrupt. It's possible you can save some or most of it with a program like MCEdit in that case.

If it happens with all worlds, you probably have some corrupted files in your Minecraft install folder. go to the folder %appdata%\minecraft and the contents of it, except for the saves folder to fix it.

Quote From dale.wessel

Please add this!

ATI drivers ALWAYS include an application that lets you manage your GFX settings and display settings. It is known as Catalyst Control Center and/or Vision Engine Control Center. It should be running in your taskbar by the clock. open it up to change the settings. they can be found under either Gaming or 3D Application settings. There, you change any setting you find to "Use Application Settings"

Forcing settings that minecraft does not have will cause the game to either become severely laggy or not work at all.

Quote from wacossusca34

Add this:

Try the Optifog / Optimine mod found Here. It fixes the lag spike of death found in some systems, and increases FPS a lot. It also has options to change qualities of certain textures instead of changing graphics from fast to fancy. To install the mod, follow these simple instructions:

1.) download the mod files you wish.
2.) drag them into your minecraft.jar file found in your 'bin' folder using WinRAR or 7Zip
3.) delete META INF if it exists.

Your Done! Make sure you are starting from a clean minecraft installation as well. Hope I helped.

Quote from wacossusca34

Also Add:

Can't get your error reports? do this to ALWAYS get a log of what is happening in your minecraft. This works for any OS.

1.) Download the Linux / Other version of minecraft.
2.) Create a text file named 'start.bat' (or 'start.sh' for Linux and Mac) where the download is.
3.) Type the following into that text file:
java -jar minecraft.jar
pause
4.) Save, then exit. Click the 'start.bat' to run minecraft, and try to re - produce your issue. When is crashes, a black CMD window should remain (or Terminal for Mac / Linux). In that window, if the full log of what happened. Post that if you cannot get a hold of any other error report.

Hope this helps!

Quote from Iceyfur

For those who are having trouble with the Java Fatal Error it is because you do not have up to date video card drivers.

First you need to figure out what video card you have, and then you need to update that graphics cards at their appropriate site.

http://www.nvidia.com/page/home.html
http://support.amd.c...ages/index.aspx

Those are probably one of the two sites you need to go to to update your drivers for your graphics cards.

The first one is for NVIDIA cards, and the second is for ATI Radeon cards. Again, the Java Fatal Error will go away once you update the drivers. It works, because I got about 20-30 of those errors, updated my drivers and everything works again. It also makes sense considering I didn't start having problems with Minecraft until I put in the Graphics Card, but didn't update the drivers. After updating the drivers, I'm able to play Minecraft again.

Another Guide i found:
Part 1 - General info

Problem: Where is the force update button?
Solution: here: Resized to 86% (was 862 x 514) - Click image to enlarge

Problem: I dont have this launcher. how can i get it?
Solution: click the first download link here: Minecraft.net download page

Part 2 - Connection problems

Problem: Can't connect to minecrcraft.net
Solution: The servers are either currently down, overloaded, or your internet connection was off whn trying to connect. try again a couple of times and if it doesnt work just wait.

Problem: User not premium.
Solution: you either did not buy the game (duh), but if you bought the game and this is still happening, this is probably a bug, which i do not know as much as other problems. but my advice is to restart minecraft, and try again a few times. also, check if minecraft.net knows you bought the game by going to this link: Minecraft has paid check and in the site URL insert at the username= your username.

Problem: When connecting to a server, i get this error: "server outdated!"
Solution: The server you are trying to connect to is running a different version then your client, and basicly you can not connect to it until it updates or you downgrade.

part 3 - Game errors/crashes

Problem: When i launch minecraft i get a black screen!
Solution: If you installed a mod, you probably missed one needed mod (mod loader, audio mod etc..) and now it does not work. To fix this, open the minecraft launcher, press options, and click on force upadte. then start the game, and minecraft will download a fresh copy. next install the mods correctly.

Problem: You installed the mods correctly, but you still get a crash/blackscreen.
Solution: Did you delete the META-INF folder inside minecraft.jar when installing? if not, again, force update, install the mods, and delete META-INF found inside the minecraft.jar file.

Problem: I installed X mods, deleted meta-inf, installed the must have mods, but i still get blackscreens! HELP!
Solution 1: There are mods that must be installed before others, i.e modloader+audio mod+GUI API. you MUST first install mod loader, after that audio mod, and only then GUI API, or else it wont work.
Solution 2: Some mods are not compatible with other mods. this in-compatibility may come from using the same item ID's, modding the same .class file, etc... if the X mods you installed do not work with each other, and you followed the instuctions, they are probably in-compatible. sorry, no solution here. you should point out the mod that does not work with the other one to its creator, so he can try and fix it.

Problem: I play minecraft, and when i open a chest, the game crashes!
Possible solution: If you had mods that add items to the game, this probably is the cause. you have an item in the chest, that does not exist in the game, you can not open the chest until you re-install the mod.
Easy solution: If the chest is not near wood, what I usually do, is put lava over the chest, and destroy the chest. the game will crash, but when you get back into the game, the chest and the item will be gone. WARNING! back up your world before doing this, since there is a very small chance the item will not burn. in that case, download MCedit and edit the chest+item out of the game.

Problem: I get massive lag. what can i do?
Solution 1: The simplest solution is to set your video settings to:
Code:
Graphics:Fast
Smooth lighting: OFF
3danaglyph: OFF
GUI Scale:auto
Render distance: start with normal. move down if lag continues.
Performence: MAX FPS / BALANCED
View bobbing: does not matter
Advanced openGL: OFF!!!
Solution 2: If the above does not work, close other programs running in the background.
Solution 3: If the above does not work, download optimine+optifog.
Solution 4: If the above does not work, Upgrade your PC/MAC. it can not handle the game.

Problem: I cant open my world! WHAT THE?
Solution: The world is probably corrupt. some reasons for this are:
Modded blocks
A power surge.
Minecraft crashing while playing a world
Java crashing
and others.

There is a corrupt world recovery thread here:world recovery thread.

Problem: I did everything you said, but i still get lots of lag!
Solution: If you have a mod that adds mobs to the game, generates the land differently, or changes game mechanics, it is probably the reason. the more laggy mod combinations are:
Mo' creatures + More creeps and weirdos
Industrial craft + Mo' something mods
Nuke tnt mod + any physics mods
etc...

The solution here is to get rid of some mods, which will usually help.
[IMPORTANT] Do not delete the .class files the mod adds or anything like that. force update, and re-install the mods without the laggy mod.

Minecraft Windows XP folder locations:

Problem: When launching the game i get an error! what can i do?
Solution: Force update. If does not work, upadte java @ java website

Part 4 - Server problems!

Problem: No one can connect to my server!
Solution: You need to port forward your router. You can find a tut on how to do this here:Portforward.com.
You need to port forward the following port: 25565 TCP/UDP.

Problem: I connect to my own server, and its laggy.
Solution 1: Instead of typing your own IP adress, type: 'localhost' (without the ' ').
Solution 2:Your PC may not be strong enough to support a server, client etc...

Problem: How can people connect to my server?
Solution: You must give them your external IP adress found here: IP Chicken. WARNING! do not give away your IP adress to everyone! This is a very important piece of info, and hackers may hack you! carefull!

Problem: I dont want to use port 25565! what can i do?
Solution: In the server.properties file, change server-port:25565 to anything you want. but make sure that when people connect to you, they type this: [Your IP]:[PORT] or else they wont connect.

There is a much shorter way and you guys won't believe it... just Force Update trust me it always worked for me

i have one problem with this.I cant find my minecraft folder anywhere

shaunwhite1982 · Feb 11, 2012

ahh ok. your game files are located in the %user%/appdata/roaming/.minecraft folder

brandop123 · Feb 11, 2012

ok i think i got it

Harukono · Mar 8, 2012

Optifine or Magic launcher help. Both of them together are what I use.

ChowMains · Mar 22, 2012

Force update will only change the the items and folders in the bin file

What this means is that if you happen to have a mod that runs from your "mods" folder and you force update you will still crash if the mod required modloader, modloadermp, etc.

Why? It's because the mods folder and the mods within it were not deleted by the force update, though modloader, modloadermp were because they were in the minecraft.jar, which as I said before was reset, removing the modloader, modloadermp, etc. classes, which causes you to crash on even a clean, freshly updated Minecraft game

ChowMains · Mar 22, 2012

I hope that made sense

An alternative to this is as follows: Windows 7

1GB 1024
2GB 2048
3GB 3072
4GB 4096
5GB 5120
6GB 6144
7GB 7168
8GB 8192

Start-> Control Panel -> All Control Panel Items -> Java -> Java -> View ->
Runtime parameters: -Xms512M -Xmx1024M

That way one doesn't have to create a .bat file.

I feel like most of this is outdated. What does someone with more knowledge of current causes of Minecraft crashes think?
