Update your graphics card drivers following these instructions: Updating Graphics Card Drivers.
Do not rely on automatic searches for driver updates.
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 is not recommended.
If that all won't help, please use the Mojang Support Center.
