How do I upgrade my OpenGL?

I have an Acer Veriton L480G Serial Number PSVA1E9003009002DB9600 and SNID 00900073196, but I have OpenGL1.1, and can’t play any games with it, what do I do to upgrade my OpenGL so I can play games?

You need to update the graphic card’s driver to get a newer version, according to the internet your PC has an Intel GMA X4500 card, which has an available driver with OpenGL 2.0!
