Just a few days ago i tried windows10 on the machine (more like a test run).
And strangely i encountered a similar (maybe the same) problem.
This time i noticed that i can provoke the problem by moving the laptop in some angles.
So i suspect that it might be a hardware problem (at least in part).
I just sent my Laptop to DELL for them to take a look.
Now im curious what they do about it.
Thx Kai-Heng Feng and sorry that i didnt immediately reported it here when i suspected it might be a hardware problem.
