Lenovo Thinkpad T410/T410i Screen Black Flicker

DISCLAIMER
Please use the method with discreet, I am not responsible for any damage caused by the method below:

Problem Description:
There's a issue of using 6Gb Ram on T410/T410i currently that results in screen

black flicker for a few seconds when using Lenovo supplied drivers v8.16.11.8955. It

normally happens on a 64bit Win7 Operating System, as far a I know the 32bit OS does

not have this issue.

The black flash/flicker usually happens when I am resizing any application window, or maximizing windows.


I check the windows event veiw, and I got the following error:
