Minecraft has been crashing for about a week. I have reinstalled MC, Java, restored backups of my saves, and multiple worlds, even a new world. It seems to be related to allocated RAM for Java (the launcher no longer works if I allocate more than 1G). Cannot play the game for more than 5 minutes without a crash. No specific actions seem to cause it.

Do not use Windows Update or Device Manager - Microsoft doesn't install OpenGL, they promote DirectX.
If you know the brand and type of your graphics card, go to the links provided above and search manually for the most recent driver for your card. The automatic detection tools of the card manufacturers are not recommended.
If all that won't help, please use the Mojang Support Center.
