IF the above dont work, that there is an option you can play aroud with that might help.

right click on your desktop and go to properities, the settings, then advanced, the troubleshoot.
then move the hardware acceleration to the far left and the apply, and try minecraft, then to the right one bar if minecraft didnt work and so on. Hope it fixes your problem!

Good Luck!

I'm having the same problem. But it only started happening when I updated my Java.
Apparently the newest Java ( Java 7 Update 4 ), is messing with MineCraft, I'm trying to find a downgrade and I found that Java 6 Update 32 works with MineCraft but I need a higher Java to start my Bukkit server >.< If you don't have a server try downgrading to Java 6 Update 32 which will make MineCraft work again. Here's a link to downgrade if you want to try this:
Java 6 Update 32, 32-Bit: http://www.oldapps.com/java.php?old_java=7615
Java 6 Update 32, 64-Bit: http://www.oldapps.com/java.php?old_java=7616
If this doesn't work then I'm sorry but I don't know what to do

Its Not My video Card Players....

You need to do one of three things, or all three
1) Update VideoCards
2) Get new graphics cards (probably need a new power supply too)
3) Get a new computer (not advised)

Well instead of buying a "New" Computer I would probably perfer you to UPDATE
Your Windows OS, because not saying XP is bad, but Windows 7s are pretty good too.
If you can't afford the Window 7 Ultimate( I think that's the best one), just get Home Premium, they are all same Window 7 but with some differences.
Home Premiums are in the 110 Dollars (About)
Ultimates are in the 180Dollars (About)

If you update your computer, the WHOLE data will be deleted, so
be sure to save all the backups you need for the future.

Computers sometimes gets error because of virus and some other shits out there.

Lowest Requirements are:
Intel CPU: Pentium 4 1.6GHz
AMD CPU: Athlon XP 1600+

Nvidia GPU: GeForce 4 MX 420 (Site says MX440, but MX420 can run it)
AMD GPU: Radeon HD 3200

You should have AT LEAST 500MB of RAM, no less

The lowest OS that can handle Minecraft is
Windows XP 32 Bit

The Version of your DirectX should be 9

Your HDD, or Hard-Disk-Drive should have at least 1GB

The Recommended Requirements are:

Intel CPU: Pentium 4 3.0GHz
AMD CPU: Athlon XP 2600+

Nvidia GPU: GeForce 8600 GS
AMD GPU: Radeon HD 6320

Your RAM requirement is 1GB

The lowest OS requirement is the same: Windows XP 32 Bit

Your direct X versions should be 9

The HDD, or Hard-Disk-Drive should be at least 1GB

I am not a "Computer Genius", but a Great Minecraft Fan :]
If I am wrong, please correct me I tried my best to help him out :[ (Plus I'm only 13)

Update your video card

"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."

I Restarted My Computer And It Work But Once i Joined a Server It said
"Ran Out Of memory" And When i Reopen it it doesnt Work ._.

Update Java, be sure you're video card is in (Hard to see if it is) you will probably:

1. Need to buy a new PC

2. Need to buy new Video card(s)

3. Update Java

4. Simply try restarting you're PC!

I'm sorry if I didn't help you're case, with all love--- ~kiefaber123
