Minecraft crashes on loading

Update your graphics drivers and try to reinstall Java.

The Intel 4 Series (and older) video cards are unable to play 1.7.4 and future versions of Minecraft. You will need to buy a new video card or computer to play new versions.

For now, you can still play 1.7.2 or older versions of the game. To change your game to a different version, start the launcher. Select Edit Profile. In the "Use Version" dropdown menu, select the game version you want. Then click Save Profile.
