can't install win 7 64 bit on my T5400. after the procedure of installing win 7 , the screen goes blank, and starting it up in safe modues doesn't help: the system says: will continue installing it, however, nothing happens it seems. The screen remains bank. I can not hook up another monitor on it since it is dvi only (running two monitors on it). I have the feeling that it has to do with the video card or so.
