Graphic card error on DELL Inspiron 3421
1 1



I installed Yosemite in my lapton Dell Inspiron 3421 for the first time (Never used a MAC). I downloaded a dmg file called "Yosemite-Zone.dmg" and installed in an usb with the tool TransMac... Everything works fine for now I installed Yosemite normally in the first boot Yosemite "OSX-Installer" start to "optimize my hackintosh" but when It finish nothing has changed.

The hackintosh works fluid but the sound and network and graphic driver does not work... I fixed the network issue ussing a TP-LINK modem but the screen and the sound does not work.

Here is an screenshot of the screen error.

How can I fix the issue of the sound and screen in my yosemite installation (I'm a noob in this as I said above)
