--------------------------------------------------------Help?

Its issue with with wrong or missing graphic card driver, or outdated driver. identify your friends graphic card, download and install latest driver for his operating system, given it is still supported by Minecraft game itself, and your friend should be alright.

He used to be able to play minecraft, them he installed windows 8 and it stopped working, he already has the latest graphics.

well then i could say going to windows 8 was bad idea.

Oh, he merely changed his OS and replaced every driver on the system. Is that all?

Regardless of whether or not he thinks he has the latest driver, he doesn't have a driver that will work. He needs a driver with OpenGL support, these only come from the GPU vendor (not microsoft) and it is entirely possible that there is no such driver for his GPU on his shiny new OS if that GPU is obsolete and no longer fully supported.
