Driver Problems (Newbie question)

Hi All.
I got a small problem with my GPU 310M (512).
When I install the latest drivers for it my screen starts blinking in black on time to time.
The drivers are the right ones, I checked it a few times. I tried to reinstall the drivers 2 times
but nothing changed. I’ll be really thankful if anyone can tell me what’s the problem and how to fix it

Thanks in advance ;]
