Hello, I was playing Rocksmith 2014 when I get the "DRIVER IRQL NOT LESS OR EQUAL (igdkmd64.sys)" error. Surfing the net I found out that this error can be solved updating the graphic driver. I have a LENOVO ideapad p500 Touch with a intel HD Graphics 4000 and windows 8.1. I tried to update the graphic driver, using this link Centro de descargas, but i couldn't because the operating system says that the driver i have is the last one; even when It isn't.
I would like to know how to update the driver or how to solve the "DRIVER IRQL NOT LESS OR EQUAL (igdkmd64.sys)" error when I'm playing.
