Hello joe,
Thanks for paying attention.
I suspect that the issue is bound to the package temperature. I often use the CPU to 100% for several tens of seconds, because i am developing stuff. After that all 3D capable browsers and Aero itself have artifacts and severe tearing if I really used the CPU power. I verified the airflow, this laptop model is pushing it with the sound of a jet engine.

- development IDEs while compiling and such ...
- I suspect that it began with some driver version about more than a year ago. I tried to change several drivers back from Intel, tried the originals from Sony, the the one which Windows Update installs automatically (the Microsoft*Inbox probably ), latest from the announcement which is posted on this forum from January 2015. The graphics driver was uninstalled always from the device manager with checking the "Delete driver software".
- I will try in safe mode now
