I have HIS radeon hd 7750 and I am using low profile. I have already reinstalled using Driver Fusion and cleaning up remaining drivers. I'm going to redownload the driver and reinstall again. Please suggest more solutions other than reinstalling please. Also, I don't think it is a detection problem because the amd driver auto detect actually detected which driver I should install. However, I can't find my graphics card on Device Manager. I guess the Standard VGA display is just microsoft's simple video driver when the actual graphics card hasn't been installed yet.
