I upgraded vista to windows 7 - windows worked then restarted computer now I have a black screen with a flashing cursor in top left corner. I have tried recovery back to vista but didn't work. When I restart laptop I have to options F2 and F12 NO F8 to safe mode if I use CTRL ALT DEL it just restarts laptop. I believe its a graphic error from looking on internet, but I don't know how to but it right. I've connect another monitor to it but it shows the same, (worth a try). I have found new drivers that will hopefully work with windows 7, but how can I install them if I can't get safe mode? Please help!!
