I've been using amd radeon hd 6700M for a long time, I noticed a while ago that the driver was inactive by itself. The laptop I used was hp pavilion dv6, I was using two video cards together ( hd 6700m - intel hd 3000). Now the amd graphics card is inactive, the intel graphics card is working, whenever I activate the amd graphics card, there is a black screen and an alarm sounds from the computer.Then I turn off the computer and start it again and suddenly the resolution changes, when I activate the amd video card inactive again, the problem is solved when I activate the intel video card. In short, this is my problem, how can I use the AMD radeon hd 6700M video card again with the intel hd 3000 as before.
