Minecraft Forums

Whenever I try to launch Minecraft, Java will just stop responding before the Mojang logo even appears. It does this no matter what version of the game I try to run. Even more confusing is that it only does this sometimes. I could run Minecraft fine one part of the day and a few hours later it wouldn't launch.

Here is the console from the launcher:

Why are you trying to load 1.4.7? I'd suggest you delete your .minecraft folder either way, and save your actual savegames (if you choose to)

I think 1.4.7 is the version of the launcher itself, I'm trying to run the latest snapshot.

Oh, yeah, facepalm. I kinda skimmed that. Make sure your Java version is up-to-date and update your graphics drivers. That's all I can say.

I've done both of these things and Minecraft is still unresponsive.

Hi,

Are you loading Minecraft in full-screen mode?

Please give us a debug log of when the issue happens.

Also, please read this guide and give us the memory dump when the game goes "Not Responding" (if it does this).

Minecraft will work perfectly fine if launched through Technic launcher, but I want to play the snapshots

I think I've done the debug log correctly but the console looks the same, I got a different exit code however.

Quote from AimbottingPyro

Running a lookup on that exit, code:

# for decimal -1073741819 / hex 0xc0000005:
STATUS_ACCESS_VIOLATION

It seems that the game ran into an access violation.

Can you give us the Event Log entries when the issue happens?

Also, are any "hs_err_pid*" files generated on your desktop or in your .minecraft directory?
