I just wanted to make this thread to hopefully lower the amount of threads asking how to fix this issue. And remember if there is no fix here that works for you search first!
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.
Do a clean install. (Windows)
First back up your saves.
MAKE SURE YOU CAN VEIW HIDDEN FILES (http://tinyurl.com/65dod2l)
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
Make sure all your drivers are up to date, for keyboards and USB to GFX cards and Sound cards.
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)

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.
(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!
2 GB RAM
Minecraft Beta 1.3_01
(fullscreen, Graphics:fancy, Render Distance:normal, Limit Framerate:off, Smooth Lighting:on)
Use the linux version instead!
It stopped the random crashings for me :3

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.

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.
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
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.

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.

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
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!

First you need to figure out what video card you have, and then you need to update that graphics cards at their appropriate site.
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.
Try these and hopefully you shouldn't be crashing
