Something very weird happend right now, I'll try to explain.
eg
So, my screen froze again, 1 second freeze then black screen, I unplugged my android, it worked again, frooze, I open task manager, works again. Now I'm here, it didn't crash, while I was writing this Google Chrome froze, I could use my mouse, 3 seconds after that, black screen "AMD Driver stopped to work" and now I'm here again. No crash.... weird.
Maybe that helps to categorize the problem. It's the AMD Driver that stops to work... and my PC just crashed while writing this, it saved the message though, so I am able to write it on my phone.
