My laptop is (Sony Vaio, Windows 7, x86, VPCEB2S1E, Graphics Driver ATI) and my problem is that my screen all of a sudden freezes by itself. I then press ctrl alt and delete and sometimes I have to wait up to 7 minutes before my screen moves and the blue screen comes up with options. Sometimes a little box appears in down right corner of the screen saying: "The graphic drive routine stopped answering and has been recovered - The graphic drive routine (display driver) AMD stopped answering and has been recovered". I suspect something might be wrong with my graphic card, but I am no expert in this area. I wonder if anyone can help me to solve this problem that my screen freezes all of a sudden. I'd be very grateful for a solution. Thanks /Ronja
