I have hp pavilion dm4 with two graphics cards, amd radeon 6470M and intel HD 3000. Ever since i installed windows 10 my amd stopped responding and all the load is taken my intel. ive tried to update drivers but it says they are up to date. when i run dxdiag it only shows intel in display where it showed both intel and amd when i had windows 7. catalyst control is also not showing any graphics options and switchable graphics option is gone. ive tried all i knew but cant get it to work. Please tell me there is a way to fix it, Thanks.
