Crashing

Whenever I start up my minecraft game it crashes.  It never used to do this up until around 5 months ago. I uninstalled and reinstalled the game and nothing works. I really need some help because I really enjoy playing minecraft and would love to continue playing but I cannot because it keep crashing and I also updated my drivers and nothing works I would love to hear mojang's answer because I don't know what to do. thank you for taking your time to read this.
