Ok so I recently did a system restore on my pc (Everything got deleted then windows 7 was reinstalled) and once it finished I got java I did all the windows updates then got minecraft again, I tried playing but after I pushed "play" an error came up after some coding. The error said: "This error is caused by a lack of up to date graphic drivers." Please help me I tried a lot of things and nothing worked.
