Hello everyone, my friend gave me his old PC Aspire X3950 with Geforce 315. I upgraded windows 7 to 8.1 and everything it's ok! When i insert my R7 250x from my main PC everything worked fine as well (without Ati Catalyst Manager). So i unistalled Nvidia drivers to install AMD's and then BAM!
When i boot PC my monitor show me that windows are loading normally and before reach the point to insert my code just black screen and i only see the mouse's pointer that i move! Those machines are more weird than womens.... :)
Any option?
*I try my other disk with windows 7 and r7 worked fine but i want 8.1 :)
