I have a T500 with a discrete graphic card (ATI 3650) and a fresh Win 7 ultimate installed on it lately.
Some times some of the pixels in the screen change color and the interesting thing is that the move in the screen.
For example when I'm using firefox and some of the pixels change color (and they usually become green) when I scroll down or up they move with the page as if the pixels of that image have changed and another interesting thing is when this happens on the desktop background when I move another window on them they disappear.
But this never happens when I switch to the onboard Intel graphic card.
Note that I installed a fresh win7 just for this reason. I had the same problem and thought that installing a fresh windows might fix the problem. But apparently it didn't work.
Please help me...
Do I need to contact Lenovo?
Thanks in advance
