hi there got an issue with my new dell inspiron 15R 5512 laptop. usually when I right click on my desktop I see the configure switchable graphics card on the menu so i can choose which application to run on the integrated Vcard or the Dedicated one but now It doesn't show there. Is there any software I can use to reinstall it? my laptop has the intel HD 4000 integrated as well as the Radeon HD 8730M dedicated in it... please help..
