hi everybody. i have an HP 4540s with windows7 and 2 display adapters intel4000 and amd radeon 7500. every time i turn on the pc a bluescreen appears and indicates error 0x116 ati kmpag.sys. i tried everything to solve it from downloading the last drivers to uninstalling windows and putting another one.but the problem still remains. i can't play my games and have to uninsatall the amd displayer adapter in order for windows to start, or else it never passes the blue screen at the beginning. i don't know what to.HELP PLEASE!
