This may or may not be a graphic problem.
- Clear private data/cache
- Clear JAVA Cache
- Check if your video card is working properly/plugged in all the way
- Check if there is new drivers for your video card/update them.
All of you guys are wrong, if a black screen is loading, it's because of the server.
If you wait for like 25 seconds, it'll load.
The new server is really glitchy, especially the new tiles and it's physics.
not necessarily... ive gotten black screen in SP and such
I know how to fix it...
It worked for me, but it will erase all your data, worlds, texture packs.
All you have to do is go to start, run, type in %appdata% and then delete your .minecraft and java folder.
Then, go to minecraft.net and play it in browser and then download it and it should work, if not, i dont know what to tell you.  [>>-i>]
I just built a new computer with an i5-2500K processor, windows 7 home premium, and an nvidia 470 video card. I have the latest version of java, latest version of the client, and up to date video card drivers. I log on to my friends SMP server, (he generated a new world about an hour ago), and after 5-10 minutes of playing, minecraft's screen goes black and I have to force close and come back. I can restart, play for another 5-10 minutes, then it black screens again. I've tried clearing the .minecraft folder in %appdata% as suggested, but it didn't solve the problem.
EDIT: I think I figured out the problem; My computer resolution is 1920x1080, so I was manually increasing the size of the minecraft window (dragging the corner of the box). When I ran at the default game size, I had no problems. When I noticed I had been running at the small default size, and went to increase the window size after a half hour of playing, the game froze (black screened) immediately after attempting to increase the window size.
EDIT2: Guess it's still just seemingly random, had a few more black screen freezes with the default window size.
just to make sure no mods do that delete the META-INF file now update java
then reinstall the aluncher and then turn pc off and on and there its fixed
I've seen a couple places now saying to turn off the pc. NEVER just turn it off. That can corrupt the file system with modern operating systems. Always use the shutdown option to shut down if possible.
Also, selecting restart should have the same effect as shutting down and powering back up, but with much less stress on the drives. Power cycling is hard on drives.
I had the same problem with the black screen when I tried to log in. I tried everything everyone here said to do and nothing worked. Then I updated the drivers for my graphics card and voila! It worked.
Okay, so I'm usually pretty damn good at fixing software issues on my computer, but this Minecraft black screen business is driving me nuts.
About two weeks ago I started getting the black screen crash. I updated Minecraft to the most recent version, and it would still crash. Mind you, this is happening in my home area, not just when I had the draw distance as high as possible while I sprinted in one direction for 10 minutes straight. I use WinXP, use the downloaded client not the browser, and have an Nvidia 8800 GT graphics card.
I tried creating a new world, figured maybe my original world got a little jacked up. No good, crashed in the new world within 5-10 minutes. Deleted and reinstalled Minecraft. Nope. I updated my graphics card drivers. No change. Uninstalled and reinstalled Java (using YourUninstaller, a program that also checks to make sure registry keys are removed when a program is uninstalled, so I'm sure my reinstall was fresh). Still crashing.
My computer hadn't been running incredibly fast in the time since I installed my OS, so I figured, what the heck, back everything up and lay on a fresh install of XP. No way that the black screen would stay then, right? Wrong.
So now I'm both heartbroken and furious, but I do of course realize this is in Beta still, so not too mad, just annoyed that everyone else out there is having fun and I'm the sick kid stuck in the bubble watching out the window. Or maybe something less dramatic.
So I have to assume that it isn't Windows, it isn't my video driver, and it isn't my version of Minecraft. Is Java choke-slamming my video card, or vice-versa? Please help!!
TLDR; i reinstalled everything, including windows, still getting black screen. wat do?
