estampador26 Posted December 2, 2014 Share Posted December 2, 2014 I did a Fresh Clean Retail Install of Mv.... But.... with internal graphics.. Intel HD3000... all work well.. except Not Aceleration... I did follow a guide in Rampage Dev Site... but still, not acceleration... So... I set PciExpress Graphics first again... the tedious EVGA NVIDIA GEFORCE GT 610 2GB DDR3.. and now... I can't Reach the Installation menu without using nv_disable=1... the same happens with the Yosemite Instalation guide here in this forum... I follow every single step but also, I can't reach Install menu without nv_disable=1... Using this flag... Im able to install everything and boot OS, and keep installing wifi, printers, etc.... but, as soon as I remove this flag... the system goes to Black Screen... in both cases... Yosemite and 10.9.... I really appreciate your help... specially those who respond to me... but... I don't now... If I use my old XFX Geforce 9800GT 512 DDR3... I don't have any problem... this card works OBB and flawless... but this card if from this machine (First Build)... I know is tedious when someone keep coming back with the same problem over and over and over... but... You guys are the expert... Link to comment Share on other sites More sharing options...
