hi
I have DELL LATITUDE E6540 with windows 7 professionnel 64bit instaled from USB key,i have all drivers with last updates but when i start my laptop the GPU AMD don't work and after restart the GPU works normaly when you disable it from devices manager old games work normaly and new games need AMD to work, i sufer from this problem since 4 months, for more explaination you need to remember that last time the GPU worked normaly so this time will not work and you need to restart the laptop, as calculated , if you start a pair of times it will work well and if you are starting an odd number of times it does not work,
ma configuration c'est:
AMD radeon hd 8790m
intel hd 4600
8gb de ram 1600Mhz
intel core i5-4200m

merci.
