Two months ago I opened up my Notebook and cleaned it. I followed istructions and I remember putting everything back in place.
Immediately after I started experiencing some problems. At the begining it was only and error message, telling me "the system has encountered an error" never telling me what. I reported a lot of times and often got response suggesting it could be a GPU hang (what is it?)
Now since the last week another thing is coming up: sometimes the system freezes; i mean: the screen freezes on a Image an the only thing that seems to work is the mouse movement. The click doesn't function.
