The black screen apears when i'm on the browser, playing games or watching videos, and when it does, i can hear sounds for a few seconds, and every time i need to reset the computer to solve, it can take 5min or 3 hours to happen.
i've tried to do a clean driver re-install, tried to use other versions but nothing seems to work. I'm sure this is a problem with the off-board gpu, because when i switch to the on-board it works fine.
Here's my computer spec:
OS: Windows 8.1 x64
CPU: AMD athlon II quad-Core Processor 2.8GHz
Graphics Card: HD6670 1GB, Driver Version: 14.12 Omega
DirectX Version: DirectX 11
Storage: Samsung HD103SJ 1TB
I bought this pc 3 years ago, never had this problem before.
