just wanna fix my macbook 2011. not even a new clean instal from pen drive works. still give me an white screen. an ssd with windows installed works on this mac, thas just increadable. i thought at first it was the video card problem and i would have to throw away the macbook but since hes working with windows the video card is being used. how could i solve this? tryied the nvram and pvram smc reset. theres is no recovery in any drive. the internet recovery i can select wifi networt, it seems he downloads the contents to reeinstalation and than the white screen shows again. (when the white screen shows the fans turns really fast as if it was doing something really havy).
