I have a HP Envy 15 3021-tx. My original AMD graphic is Radeon HD 7690M but after i clean install window 7 it install amd radeon 6600m and 6700m, same graphic driver after i installed window 10. After downloading the latest catalyst, installing the catalyst at detecting display driver it just crash into black screen. So currently im using my intel hd graphics 3000. Any idea which catalyst should i install or it just meant my graphic card is spoiled ?
