Dennis, I got lost – there so many problems described, but I didn’t manage to find the cure for mine. I read all this topic and I will follow exactly what you recommended, without updating the BIOS.
My Pro (K9C6) crashes under Android – black screen, difficult to boot after, strange charging time, etc. Since it is used mainly by my spouse (a faulty birthday present, don’t ask me how I feel now), she stays most of the time in Android OS. I promise to check and report how it handles under the Windows after the updates.
Is there any detailed topic for the Android crashing as well?
What I got from Geekbuying.com, which were nice to respond twice already, is a reply with a suggestion to try to install the latest firmware and flash:
