I have dual graphics laptop.Recently i just reinstalled my OS,when i install my intel hd graphic card driver the display is working properly but then when i install my second graphic card driver and that is Ati/Amd the display just gone black.i tried a couple of things but it just won't do it.By the way,I got the drivers from the laptop's manufacturer site.
Somehow i did try installing the latest driver i got from amd site,went well at first but it became laggy and keep restarting after the window log on.I havent found any solution for this problem so please help me i will really appreaciate your kindness and also forgive me if something is wrong with my english..A really big thank you for those who's helping
