Well, I did a clean installation of windows 10 then I proceeded to install the latest AMD drivers for my system, but I was unable to install the display drivers as it seems to be not compatible with windows 10, my display drivers version got stuck at 15.200.1045.1, so as a consequence I'm having the following 2 problems:
#1: In the startup process after the windows logo, my screen turns black without the mouse cursor for about 1 minute.
#2: I can't recover my laptop from sleep mode, when doing so I got a blue screen message saying:
"Your PC ran into a problem and needs to restart. We're collecting some error info, and then we'll restart for you.
If you'd like to know more, you can search online later for this error: CRITICAL PROCESS DIED"
My system info:
HP Pavilion g6-1d21dx
Windows 10 - 64bits
Factory OS: Windows 7 SP1
AMD A6-3420M APU With Radeon HD 6520G graphics
