So, from the beginning, Games like minecraft (-_-) used to work before I upgraded to windows 8,1. I think I have the correct updated driver but I have a suspicion it was auto downloaded from windows, and as far as I know these drivers dont have opengl support. When I try using Intel Driver Upgrade Utility, it comes up with no drivers. I have a dell optiplex 380, intel pentium e5800 with intel g41 express chipset. Any help is appreciated
