How to fix Minecraft Java Crashes

Big Update is Big

Hello, it’s now 2014 and this post is almost exactly 3 years old. I just want to let you know that there’s a new more updated post on The Noob Network with our top 5 tips on how to get Minecraft running better! Old post is below this line.

April 21st 2014 update: I decided to move the old page into a post format, and I included a tutorial on how to find out if your computer is running a 32 or 64 bit windows installation.

A quick note: if I do not reply to your comment, it’s not to ignore you, but simply because I do not have an answer to your question.
My original post posted May 30, 2011:

Minecraft-fatal-crash-glow_1743434I recently acquired a brand new computer with an x64 (64 bit) Processor and x64 OS and noticed that even with all the necesseties of Minecraft installed it would still crash. Almost always, Minecraft would just freeze for 5 seconds and then crash with a black screen. It’s a really common issue and the most “work around fixes” are just you changing the viewing distance to anything but far. I searched everywhere for a fix, but couldn’t get a fix for this crash. Sure the setting viewing distance to anything but far would slightly fix the problem but only by prolonging the crash by say 15-30 minutes.

I checked what version of Java was installed on my machine and it was an x86 (32 bit) version. When most install a component such as Java, some automatically think that it’s fit for their system no matter what. If you go to the java download page you’ll see the big red download button, but underneath it says “Not the right operating system? See all Java downloads here“. Go there ( and download the x64 version of Java and

I uninstalled my 32 bit version of Java and downloaded the x64 version and installed it. I have had Minecraft idling for an hour without a crash and I will update this post when I know that this fixed it.

So if you have the issue of Minecraft constantly freezing for a minute or so and then crashing here’s what you can try to do to fix it;

  1. Find out if your computer has a 32 bit or 64 bit processor in it and which of those Windows is running in.
    Almost every new computer built today is a 64 bit system, but if you are unsure because you’re using an older machine here’s how to check:

    1. Click the Start Menu and type system into the search box.
    2. Click the System icon that pops up in the menu (usually the first result).
    3. You should see this window pop up with all your system information:
      Windows 7 System
    4. Your system type is displayed under the Windows 7 logo, in the screenshot it says that machine is running a 64-bit OS.
    5. If your system is a 32 bit system, Java might not be the problem for you but something else. I would check the Minecraft Support forum and see if they have something on the subject!
  2. Everyone hates to admit it, but in the midst of things you or whoever installed Java on your machine might have overlooked that the 32 bit version of Java was installed on a 64 bit system. Go to and download the 64 bit version for your OS (Windows, Solaris or Linux)
  3. Launch Minecraft
    See if Minecraft will run on any rendering distance and play for as long as you like

Please let me know if this fixed it for you, I’ll update this post once I know for sure that it solved my problem. I’ve had Minecraft running in the background while writing this and it’s still running!

Edit: Minecraft hasn’t crashed all day month year, I’ll call this a confirmed fix!

If this helped you, please share this page with your friends just in case they run into this problem too!

Frequently Asked Questions

I decided to answer some questions of different search terms that brought people to this page.

Can I play Minecraft if my computer is 32-bit?

Yes you can, just make sure to use the right (32 bit for 32 bit computers and 64 bits for 64 bit computers) version.

  • Roger


    Can you post, or send me, the stack of crash that you were seeing before switching to 64-bit JRE? We are looking into a crash at the moment and saw your post and would to know if the crash and solution are related to what we are investigating.

    Thank you,
    Java SE Development team

    • Andreas

      Hello Roger, thank you for your comment.

      I’ve since fixed the problem and it’s no longer a problem for me personally. Installing the 64-bit Java Runtime Environment on a 64-bit OS seemed to have done the trick. I haven’t had any problems with this particular application to run since I did this (May 30th 2010).

      But if anyone else has Minecraft crashing for them, please feel free to reply to Roger’s post above with your crash message.

    • dbulm2

      hey roger, you are in luck because I had previously sent the error to mojang and they sent back an automated message with the whole thing saying that the message was recieved :D it is:

      of course that is with mods on, not sure if thcould help? i never had the error that Andreas had sorry. Ut was for a crash with a few mods that are compatible together and running a mcpatcher activated 256×256 texture pack.

    • Martins

      Hello Roger.
      I have a big problem:
      My savegame world is very large so the java crashes every 5 minutes, but worst of all-
      delay between crashes gets smaller and smaller…
      now i cant even play for 2 minutes :(
      When it crashes it says me that it had ran out of memory, however i have left pretty much space on my local disk, where is the java installed. So can you lease help me somehow fix this problem? please reply.

      • Why does it want my name?

        By memory it means RAM.

    • Wunder

      So um, i have the 32-bit for java, and it still crashes. I think it’s because i am using an old Window 7 laptop. If not then can you help me? I was thinking about getting a new comp but my budget is tight right now.

    • http://None Nolan

      Roger, i have the same issue with the new minecraft installer, which i know is independet from JRE as state on
      when i load minecraft it works fine but if i go intoa world or anything it crsshes. I am running windows 8.1 64bit dedicated 5 gigs ram to minecraft out of 16, use intel HD graphics 4600 and a Intel Core i7 Quad core at 3.20 Gighertz. any suggestions on how to fix this are appreciated.(2-28-15(5:49pm))

  • Dan

    hey,this was helpful, but how do i stop the crashing if im on a 32-bit system windows? you crashing in the post sounds exactly like what im dealing with… thanks

    • Andreas

      This is a dumb reply from me, but did you by chance uninstall and reinstall your java runtime environment? I don’t have any machines with 32 bit operating systems any longer :( wish I could be of more help.

  • Mark

    Thanks a lot dude. I really appreciate this post, it was exactly what my issue was.


    • Andreas

      Glad to be of help Mark!

  • peter

    hello, im having the exct same problem.
    i got a 32bit version of win7 on a very fast pc, and still minecraft java crashes every 5 minutes and my CPU OVERHEATS!!!!

    How can i fix this?
    install 64bit on a 32bit pc??


    • Andreas

      Hi Peter, that wouldn’t work unless you have the capability to run 64 bit applications on your machine. I wish I knew the answer for you but all my machines are 64 bit :(

  • tinyninja

    I did this and I’m still having crashes in the nether with the balck screen of death. Also now minecraft won’t even load in the browser (and I’m running a 64 bit system). Any thoughts?

  • jimi

    Fantastic thread. I was running 32bit java on me 64bit windows7. I have to have both versions installed so I can use my web browser but that no prob. U guys have saved me from a world without minecraft and for that I thank you.

  • Mads

    This didn’t help me at all :( I mean, this seems to be good advice, judging by all the others that were helped, but mine still crashes all the time.

    I’ve got both Java versions installed, but I still can’t play it in browser, nor offline. If I try to scale the window, it freezes, and in the browser, it works for about a minute or so, before Java crashes. I’ll admit my computer isn’t the best out there, but it is built for gaming, so it should be able to run a simple game as Minecraft, right?

  • MindMemento

    Hello, I hope you can help me with this. I have 3 problems with Minecraft. First, when i open minecraft, it takes 1-2 hours to it open and before it opens my computer fan starts roaming crazy and makes much noise. when my minecraft opens, i can play it 10 minutes and in crashes, or the other thing what usually happens, is that my computer shutdowns automatically. What can i do? I have…
    -Windows 7 Home Premium 64bits
    -Intel Core i3
    -2.13 GHz (Graphic Card)

    and yes i have been alot with my computer on sofas or like that where it may have sucked dust. But is there any other ways to stop the overheating/crashing/whatever it is so i could just play minecraft normally?

    PS: thank you for your assistance.

    • Andreas

      Sounds like maybe your fans are busted or there’s something whack with the cooling, Minecraft should not take 1-2 hours to open (!) and the frequencies of the crashes and the automatic shutdowns sounds like it’s definitely an overheating issue.

    • Phyremaster

      Hey, from this it sounds like your vents need to be cleaned. Just recently, my computer was repeatedly overheating. I suggest using your breath, or, if that doesn’t work, canned air to blow out the vents. Desktop PC vents are usually on the back, and laptop vents are usually on the sides and/or bottom.

      Hope this helps!

    hey, can you guys tell me what happend to my minecraft? heres the crash reprt:

    Bad video card drivers!

    Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
    This can usually be fixed by updating the video card drivers.

  • Justin

    Wow thanks so much… i cant believe such a simple fix was the cause for all my minecraft woes! i feel like an idiot lol

  • Matthew

    Hey, I have Windows 7 Home Premium 64 bit, but my minecraft works only with Java 32 bit, I uninstalled the old java (32-bit) then I installed 64 bit one, and I couldn’t open the minecraft application.
    It says that minecraft cannot find the Java Runtime, and cannot find an application of java(32-bit)
    So, I think my minecraft works only with java 32 bit, by the way I have a cracked version of minecraft, downloaded from BitTorrent.

    Please help!

    • Andreas

      Hello Matthew, it sounds to me like your system should be able to run Java 64 bit, but perhaps the fact that you’re running a pirated copy might be messing something up. I don’t have a pirated copy myself and can’t help you out. Sorry :(

  • Jelmer

    Hey, I had a problem with minecraft crashing after 5minutes-2hours, I looked into my JAVA situation, and I did have a 32-bit installed on a 64-bit system so I hope my problem is now fixed.

    However: Last time it crashed, the crash didn’t just shut down my computer(which I already considered kinda serious) but I got a 0xC000021a error on a Blue Screen and it was a bit of a pickle getting my computer to start up again.
    Now I am sort of hesitant to start Minecraft because I don’t know if I fixed the problem that was causing my BSOD. Has anyone ever experienced these kind of troubles before as a result of this Java-problem? Did this problem cause anyone else’s computers to power down to standby-mode? Is this Java-thingy known to have caused BSOD before?

    Hey guys!
    I managed to run a Minecraft server well and friends can join no problem. I wanted to increase how much ram my server uses. I looked it up and people said I needed to update to Java 64-Bit. When I tried updating my java, I updated successfully. My Minecraft server however, is no longer allowing my friends to join.

    My computer is IN FACT a Windows 8, 64-Bit computer with 16 GB Ram, so I can’t see the problem. When I downgrade back to 32-Bit Java, it works perfectly again.

    Please help? :)
